How to Pass a Drug Test for Marijuana

how to pass a drug test for marijuana

Stop smoking. Right now! If you are reading this article then there’s a good chance you have a drug test coming up. The best thing you can do to pass a drug test is put as much time as possible between a smoke session and your test. I know that’s not what you want to hear, but it’s truly the best advice I could give you.

This post is sponsored by Check out their site for extra information about passing drug tests. 

If you’re looking for something specific you can use the links below to jump ahead to a specific section, however; I certainly recommend reading this article in it’s entirety (I know it’s long, but it’s worth it).

Please be aware of all laws concerning the tampering of drug tests. The following article is for informational purposes only. 

If you know you are going to be tested regularly (military, probation, etc.) then you may want to consider not smoking for a while. The stress of never knowing if a random screening is coming may not be worth it. Of course, this is a personal choice that you’ll have to make for yourself – I’m certainly not here to judge.  You may be using it medically, and don’t have the option to quit smoking all together. All I can say is I sincerely feel for you. A system that creates a criminal out of the ill goes against everything that should be moral.

[Tweet “A system that creates a criminal out of the ill goes against everything that should be moral.”]

On the other hand, more often than not, you don’t have a ton of notice. If you don’t have enough time to let your body naturally detox then you’ll need to find an alternative method to pass the test. That’s what this article is all about.

The information presented in this article is a combination of personal experiences, experiences of friends, and a bunch of research. I tried to compile as much knowledge as I could, but frankly I need a little help. If you’ve tried any of these methods or if you know something that isn’t covered in the article let me know in the comment section at the bottom of the article. The more relevant details the better (e.g. height, weight, smoking habits, method used). This article becomes much more useful once people share their personal stories and advice. As always, feel free to put a fake name and email address when prompted.  

There is no 100% guarantee that any one method would work for everyone. No matter which method you choose there is always a possibility of failure. 


Urine Screening

Urine is by far the most common method used to test for marijuana use. Unfortunately, marijuana can be detected in urine longer than many of the other testing methods.

How Long Can THC Be Detected in Urine?

This is a very complicated topic. For this reason, I wrote an entire article dedicated to how long weed stays in your system. Please refer to that article for more information.


Types of Urine Tests

There are two primary ways that urine is tested for marijuana. Unfortunately, neither one of them is multiple choice. Each one has it’s own set of pros and cons. They are both briefly explained below. 


This method for urine screening uses test strips that are basically identical to the ones that you can buy over the counter or online. The test strips are briefly dipped into the urine sample. A different chemical reaction happens depending on if THC is present or not. Typically, 2 lines on the strip means negative, and 1 line means positive.

The test strips not only check for THC, but they may also test for creatinine, nitrite, pH ,oxidant, specific gravity, glutaraldehyde, or possibly others. If you drink too much water (discussed later) these additional elements won’t be present, and the test may be considered inconclusive or you may simply fail. Also, if you replace your urine (also discussed later) it must contain these properties.

This is the most common method of screening urine for THC. They are not 100% accurate and rarely can produce a false positive. If you dispute the results (usually a lost cause) you’ll most likely be tested using a GC-MS test, which is discussed next. 

If you have any experience disputing a positive result please let everyone know in the comments. 

Gas Chromatography – Mass Spectrometry (GC-MS)

This test is more in depth than the immunoassay test. It’s also more expensive which is why it is used less often. If your first test is positive then they can do a GC-MS test to rule out the possibility of a false negative.

For this test, your sample is run through a big fancy machine which gives a much wider range of data. This can be a problem if you’re using synthetic urine (discussed below). They are able to test for additional proteins and all types of other stuff. This isn’t to say a GC-MS test can’t be beat, but it is more difficult to fool. 

In short, you do not want your sample to go to this test. If you test positive on a GC-MS test then you have pretty much a zero chance of fighting it. 

How To Beat a Urine Screening for Marijuana

The Golden Rule: Never use the first or last part of your urine stream for a sample. Only let your midstream enter the cup as it carries lower levels of toxins.

[Tweet “Midstream Only #pisstest #goldenrule”]

If you plan to use any of the methods below (except replacing) I recommend getting some THC test kits so you can check the results at home. The test strips are basically the same as the immunoassay test, so they make for a pretty reliable comparison. 


All-natural is certainly the way to go if you have some time. None of these are super quick, but they will help speed up the process a bit. The exact amount of time is going to be different from person to person.


This only helps if you have more than 72 hours before your test. Do as little exercise as possible once you’re less than 3 days away. Here’s why: THC is absorbed into fat cells. Lots of exercise will burn off the fat and release the THC. The more fat you can burn the better off you’ll be. Once you’re 72 hours away you want want your body to stop burning/releasing fat. 


The diet works similar to exercise. If you are more than 72 hours away from taking a test then you should eat very lean meals with lots of fiber. Once you get to the 72 hour mark switch to a high fat diet with lots of red meat. Your body will start saving the fat cells and help keep less THC from entering your kidneys. 


A diuretic is anything that makes you urinate more. It does not actually clean your body or detox you of any THC. Diuretics do; however, help flush out your bladder which lowers the amount of THC in a sample. There are diuretic pills, but a lot of them are prescription. Of course, there’s plenty of diuretic solutions available online, but that’s not really sticking to the idea of passing naturally. Here’s a list of common diuretics you can find at your local grocery store:

  • Caffeinated drinks such as tea and coffee
  • Cranberry juice
  • Citrus fruits and drinks
  • Lettuce and Spinach
  • Garlic
  • Palo Azul (discussed later)

There isn’t much more you can do to naturally speed up the detox process. If you have several weeks you can buy a few home testing kits to know if your efforts are paying off quickly enough.

From here, I’m going to talk more about flushing/diluting with water. I don’t consider this method natural, because it requires you to take several supplements in order to achieve the best results. Drinking water does; however, increase your likelihood of passing, so it’s worth taking a look at. 

Diluting Your Urine By Drinking Water

Drinking excessive amounts of water essentially flushes out your system and dilutes the toxins in your urine. Do not confuse this with actually being THC free. It’s merely the illusion of being THC-free. The concept is simple. Start drinking lots of water starting the morning of your drug screening. You should aim to urinate 3 – 5 times before the test. Continue  to drink lots of water until the test is complete.  (Make sure you don’t go overboard. You can actually die from drinking too much water – for real. It also puts a considerable amount of strain on your kidneys. )

The problem with flushing your system with water is that it also lowers the amount of other substances that occur naturally in urine, such as creatine. The color will be clear which is a dead give away that technicians are trained to look for. If you pee clear then there is a good chance that your sample won’t even make it to the testing process. For this method to stand a chance, you’re going to have to take a supplement(s). It helps to start taking the supplements a few days before testing if possible. Always read the labels on supplements and don’t overdo the dosage. 

  • B12 – This will add a yellow color to your urine, which will keep lab technicians from becoming suspicious of the sample. This is the most important supplement in this list. It can be purchased at pretty much any pharmacy or health for store. You can also purchase it online
  • Creatine – Urine tests will check for the presence of creatine. If you dilute then there will not be much creatine in your body. Taking a creatine supplement will help raise the amount of creatine in your body. Creatine does come with considerable health risks. I advise reading this article and speaking to your doctor before you decide if taking creatine is right for you. 
  • Multivitamin – A good multivitamin will help replenish vitamins and minerals found naturally in your body. 

Some people claim to pass urine screenings using only the B12. The creatine and multivitamins may not be completely necessary, but I tend to ere on the side of caution. 

Labs are constantly evolving, and testing for additional elements. Specific gravity and PH level are just a few things that labs test for specifically to authenticate the sample. A GC-MS screening has the capability to check for a whole array of proteins, vitamins, and other bodily stuff. The water + supplements method is better than nothing, but it’s certainly not guaranteed. If you have time, use home test strips to test the effectiveness beforehand. 


The effectiveness of niacin has been very hotly debated. There are a lot of people who swear by it. I have used niacin and did in fact pass a drug test. I did have 10 days without smoking and had done the dilution method as well so it’s difficult to know if the niacin contributed or not. It helps if you have a few days notice to start taking the niacin in small doses. 

If you take excessive amounts of niacin at one time you’ll get a burning sensation and turn bright red. You may also develop hives. I recommend taking 250mg or less a day. Everyone reacts differently so start slow.

There are people who have claimed to have taken high doses and passed tests in a short amount of time. Given the health risks, this is not something I would personally recommend, but sometimes desperate times call for desperate measures. You should be fine to take up to 1000mg a day as long as it’s not over an extended amount of time. This also assumes you don’t have any pre existing conditions that might react to the niacin. If you take that much then prepare to be uncomfortable for a few hours. You’ll also look terrible so it’s nice if you don’t have to go in public when taking higher doses of niacin. 

If taking large doses you may want to leave some time between the screening and your last niacin ‘flush’. You want to make sure you’re not blood red when you go to take the drug screening. It’s definitely a cause for suspicion. 

I do believe that niacin helps to some degree, but I’m still trying to gather more evidence to determine how reliable it is. If you’ve tried using niacin on a drug test it would be super helpful if you could tell everyone a little bit about it in the comments. 

I think niacin is best done in small doses over a few days to a week. I also wouldn’t rely solely on niacin. Instead, I would use it in addition to some of the other methods discussed in this article. 


Do not drink bleach. Yes, you can find people in forums claiming to have drank a cap full of bleach and passes a test on short notice, but I don’t care. Have you ever read the warning label on a bottle of bleach? It probably doesn’t work anyway. Just don’t drink bleach – ever. That’s all I’ve got to say about that.

Detox drinks

Let me start by saying that the word detox is a pretty misconceiving term. These drinks are not detoxing or cleaning your body of anything. In essence, the detox drinks are doing the same thing as diluting with water and supplements. Any ‘detox’ remedy will also instruct you to drink lots of water, and the ingredients are a variety of vitamins and supplements used to make your urine appear undiluted to the test. 

As always, the more time you put between smoking and the test the better off you’ll be. 

Do detox drinks work? My answer is yes – in some cases. I have personally used a detox drink to pass a drug test. I was smoking heavily, but I had three days notice and quit smoking. I followed the instructions exactly, and passed a pre-occupation test at a lab. I do believe that I would have gotten the same results using the dilution and supplements method.

Detox drinks are also super overpriced, but they can be convenient compared to buying a bunch of different supplements. This is the detox drink I used to pass a drug test. There is absolutely no guarantee that it will also work for you. If you’ve used a detox drink let everyone know in the comments. We can compare which drinks gave better results. 


This method is different than all the rest. The other methods were ways to make your own urine passable. This method negates using your own urine all together. Instead, you can ‘smuggle’ in clean urine, and never have to worry about how much THC is actually in your system. This method certainly comes with it’s own risks. It works best when you are taking a screen where you are not being directly watched. This is often the case for pre-employment lab screenings. On the other hand, probation or military screening are often performed with someone watching you. If you are being watch during the test then it can get very tricky, but it is possible. If you are unsure if someone will be watching you then I suggest using one of the previous methods as a backup just in case.

Real vs. Synthetic Urine

If you’re going to replace your urine then you’re going to need a proper sample. There are two ways you can go about getting a sample that is THC-free. You can 1) get a sample from a friend or family member who doesn’t smoke weed (or do any other drugs for that matter), or you can 2) purchase a synthetic urine. Each method has it’s own pros and cons which are discussed below. 

Real urine is great because it’s pretty much guaranteed to have all the right creatine levels, specific gravity, and proteins. Use a plastic container to collect the urine. You will need at least 3 ounces to take the test. If a sample is left unrefrigerated it will only remain good for 6-8 hours. This is fine if you are collecting the sample right before the test. If you are collecting the urine sample earlier then you’ll need to refrigerate or freeze the urine. In the refrigerator, the sample will last around a month. A frozen sample can be used for 6 months – 1 year. I recommend using the freshest sample you can get. From here, you’ll need to know how to keep the sample at the proper temperature (discussed below). 

Synthetic urine is created in a lab instead of in a human. Synthetic urine can remain usable for 1-2 years unrefrigerated. This is a pretty good solution if you don’t know exactly when you’re getting drug tested or you don’t know anyone who is THC-free and cool with you borrowing some piss. Synthetics are also helpful because the come with the necessary equipment to ensure proper temperature (discussed below). Make sure you check the expiration date on the box. I would not buy synthetic urine that does not have an expiration date. The main risk is if a lab begins to test for a specific protein that hasn’t been added to the lab sample. I have used synthetic urine for several drug screenings and it’s always worked perfectly. There are several synthetic urine manufacturers, but I’ve used QuickFix and XStream. If you’ve used another brand of synthetic urine let everyone know in the comments how the screening went. 

Concealing & Maintaining Proper Replacement Urine Temperature

If you’re not being watched then the easiest way to get caught replacing a sample is if it’s not the correct temperature. The perfect temp is 98.7 degrees, but it’s okay if it’s a little over or under (under is better than over). Between 92-100 degrees is generally okay. 

Synthetic urine typically comes with a bottle that has a temperature gauge on the side. This thermometer is super helpful when making sure your temp is just right. If you’re not using a synthetic then forehead thermometers work great. I like to use hand warmers (the kind you take camping) to warm up the sample. Just attach the hand warmer to the outside of your bottle with a rubber band, and keep an eye on your temperature gauge.  

I use athletic tape to secure it to my leg. It’s a lot nicer than ripping a bunch of duct tape off your leg, and you can find it at any pharmacy. You’re going to want to secure it to the inside of your leg as close to your crotch as possible. Wear thick and loose fitting pants. Jeans are perfect. Here’s my procedure: 1) Use hand warmer to heat synthetic urine to 100 degrees. 2) Use the hand warmer to warm the part of my leg that the bottle is touching. 3) Remove the hand warmer, and strap the bottle of urine to my leg in a parking lot near (not at) the testing facility. 4) Sit around and wait forever in the lobby. This is why I heat it up to 100 degrees. It typically drops a few degrees by the time my name is called. 5) I empty my pockets into a bin as instructed by technician. 6) I walk into lab bathroom and close the door behind me. 7) I remove the sample, check the temperature, and simply pour it in the cup. If it’s too hot, you can cool it off by blowing on the sample. If it’s too cold though – your pretty screwed. 8) Strap the bottle back to your leg and you’re good to go. 

If you’re a girl, then you have an extra option. If you use a cylindrical plastic container then it can be inserted vaginally. This will keep the sample at body temp really well. Make sure the container has time to warm up. You can use a hand warmer and thermometer to get it to the right temp if you don’t want to insert it until right before you go in. Otherwise, you’ll want to insert the sample at least an hour before taking the test to make sure it’s body temp.

If you’re being watched then everything changes. You’ll have to practice and be extremely careful to look natural. I’ve never been in this situation so I can’t say for sure how intense it is. I do have a buddy who got caught. He was being watched, but was able to pull of squirting synthetic out of a bottle. Unfortunately, he forgot to close the lid before releasing at the end so it made a sucking sound as the air rushed back in. Needless to say he failed the screening. 

For guys, you can buy a whizzinator. It’s basically a fake penis that you strap on so it looks like the replacement urine is actually coming from a real penis. It’s super weird and pretty expensive, but I know more than one person who uses it on a regular basis without incident. If you don’t have the money for an actual whizzinator then you can go the cheaper route by purchasing a urinal strap kit and making your own. 

If you know another way to conceal replacement urine let us all know in the comments. 

Urine Additives

There are lots of companies out there creating additives that claim to make your urine clean. The idea is that you pour a chemical into your dirty sample and it’s made clean. I absolutely do not recommend ever using this approach. Most tests check for additives, and you will fail the test. If you’re going to smuggle in something then bring a clean sample instead of a chemical to add to a dirty sample. 

Palo azul tea

This one seems to be a little newer to the game, but has been picking up speed pretty quickly. In short, Palo Azul is a root that grows in Mexico and Texas. You take about a half an ounce and boil it into 1-1.5 gallons of tea. You drink the tea 24 hours before the test and magically you pass. I’ve never tried using Palo Azul so I started to do some research, and here’s what I found. 

There are a lot of internet reviews about this stuff. Some are good, and some are bad. The problem is that a lot of the reviews appear to be coming from the sites who are selling Palo Azul. They are written very awkward (sounds like a sales  pitch), and always contain links to buy the product. I’m can’t say for sure how many of the reviews are genuine, but I would be my bottom dollar that a large majority are fake.

I also find a lot of reviews that say they tried the tea and still failed the test. With this in mind, I would not trust Palo Azul tea alone, but it may not be a bad idea to use this along with some of the other methods.  It’s a great diuretic which is helpful but certainly no magic spell. If you have used Palo Azul let me know if it worked in the comments. To avoid more noise in the area, I will not allow comments that contain links. This is purely an attempt at getting unbiased information from people who are not involved in the Palo Azul industry. 

Blood Testing

Blood tests measures active THC which is quite different from the THC that is screened in a urine test. THC will show up in your bloodstream for anywhere from a couple hours to several days depending on your level of use. In extreme cases, it may be traceable for up to a week, but that would be unusual. This method is often used in association with DUIs and car accidents. Lab technicians can analyze the level of THC and predict whether or not someone was high at the time of accident. This is not perfect though and puts regular users at risk for appearing intoxicated when they weren’t.

If you have a few days then you should be fine. If you have to take a blood test on short notice then I don’t know of anything you can really do short of a complete blood transfusion. Exercise may circulate the blood and help, but this is purely a thought – I have no proof whatsoever that this is the case. If anyone knows ways to detox your blood faster please let everyone know in the comments.

Saliva Swab

Saliva swabs are most commonly used by employers because they can administer them on the spot. They can also watch you perform the screening unlike urine tests. THC can be detected by an oral swab for anywhere from a few hours to a day. If you’re being tested at work, and you haven’t smoked that day then you’re probably fine. Of course, make sure to brush your teeth and use mouthwash. This stuff wont work miracles if  you smoke right before the test, but they can help reduce toxins to some extent. Drop a comment if you know any quick fixes to pass a saliva test for marijuana.

Hair Follicle Test

This method had come under a lot of scrutiny. Hair tests are highly biased against african americans as toxins are more easily detected in coarse, dark hair. THC can be detected in hair for years if it doesn’t get cut. The THC gets embedded in the hair and remains there usually until that portion of the hair is cut. Also, it takes a week or two for your hair containing the drug to grow above the scalp to be cut. So, hair follicle drug tests have a much longer lag time before THC detection. This means, if you only smoked once, it won’t show up on a hair test for a few days up to a few weeks. 

This test is most often used when someone is trying to establish whether or not you’ve been smoking habitually over the last few months. They are more expensive than other types of tests so this makes them less popular.

Don’t think shaving your head will get you off the hook. Technicians can take hair from pretty much any part of your body. I guess you could shave your entire body and try to pass yourself off as a competition swimmer, but I bet you want to keep your eyebrows.

Given the bias of the test I don’t think they should ever be used, but unfortunately they are still used sometimes. There are several hair shampoos that claim to ‘detox your hair’. I have read soooo many reports of these shampoos not working that I’m not even going to link to them. If anyone has experience with these shampoos or another method for hair please let everyone know in the comments.


I’m going to drop a bomb on your right here at the end. THERE IS NO SUCH THING AS A RAPID DETOX. It simply doesn’t exist. It’s just not how the human body works. That doesn’t mean that you can’t fool a drug test. Just keep in mind that’s what your doing – fooling, not detoxing. I always recommend buying some THC test kits to check your levels yourself before going to take a test. 

This is by no means the end all – be all guide to drug testing, but I do intend for it to eventually become a definitive guide. In order to make that happen I really need help from you. If you have any experience or information to add please let me know in the comments. Feel free to use a fake name and email address when you leave a comment.

    • me me says:

      thankyou firstoff, I can defiantly tell ur right on. I have been drug testing for years, being on suboxone. of course smoking pot is usually out of the question but have past a several times with notice to be able to smoke first. a week minimum before a test. I only smoke a bowl on ever so rarely at least 3wks in between sitting. I have been gaining weight over the past 2 yrs I am 33y.o.a. 5’7″ and 220lbs….. I smoked and ended up having a fluke test an hour later. my question is, is it possible that it did not metabolize yet? oh and fell free to ask any questions.

      • Mary Jane says:

        Hmmm, this is a really interesting scenario. If you were clean before that one smoke then I could imagine the THC not making it through your system, but To be completely honest I have no idea. This is a new one for me. Please let us know how it turns out. I would like to add something about this to the article. Thanks for sharing, and best of luck!

        • Amber says:

          Hey, I’m a 22 year old woman, 5’3 about 165 pounds. I used to smoke all types of bud (mostly regg), however, I was clean for two months up until last week and yesterday. When I did smoke those 2 times it was of exotic and it was a small joint. I was wondering if I should worry about it being/staying in my system? I’ve been taking niacin 500mg 2 times a day while drinking water regularly. How long till my urine is clean again?

          • Mary Jane says:

            I can never say for sure since everyone is different. The best thing to do is go to your local pharmacy (or amazon) and grab some home test kits. They’re relatively cheap considering the peace of mind they provide. Cheers.

          • Emmitt says:

            somthing about niassi. it cleans your bloodstream if there’s no thc in your bloodstream then you can not fail. right? I take 500mg about 24hours befor the test & drink lots of watter. by lots I mean enough to make your p clear. then 10-6 hours before the test take 500mg agin. in that 10-6 hours between taking it the second time and your test drink at least “5 letters of watter. it’s worked for me for years. just bont expect it to make you pass for anything but thc. also all of my tests have been lab test.

        • Booyah says:

          Does detox tea and exercise help reduce Thc in body?

      • RazorRay says:

        Since fat cells are what stores the evidence of pot smoking , I think as THC metabolites and not as actual THC itself (in the urine this is so to my knowledge) , (metabolites being the product of how we metabolize THC) , Even though there is an agreed upon time limit for those fat cells to be burned up as calories and release those metabolites sending them eventually into your urinary tract , it is without doubt possible though unusual to be coming up clean well past detection times simply because one has only then burned those fat cells , those that may still remain in other areas of fat in your body. Heard stories of folks failing U.A.s for THC when they claimed to have completely abstained , up to months , some saying years. This is because , vaguely , their bodys have only just gotten around to metabolizing some long stored THC fat cells. Usually this may happen to individuals with very high bodyfat levels. On probation and parole , these people if objecting strenuously and denying guilt , sometimes the dept/P and P , PO officer may allow for a repeat test , (maby a nanocount or some such phrase , I forget) , which is supposed to verify the validity or not of the positive , as nanogram count will drop off a certain rate , or a blood test , etc,… can verify your innocence. All that is a little vague I know , but I am fairly certain of this truth. Easily verified with a little research.

          I do not smoke, but my husband smokes everyday in the room while i sleep, and i have a hair follicle test in about a week. Wondering If you know would i test positive even though i myself have not smoked in years.

    • Anthony says:

      Hi. I figure dropping a line this way should be easiest thing I can do at the moment. Anyway, here’s my deal. I was a heavy smoker, smoked a 1-2 bowls each night. Stopped smoking on March 17th. Began working out and changing diet habits to help work THC-COOH out of my system in hopes of passing a test. On April 1 (in the middle of doing 40 mins Insanity in the morning, 8 mile bike ride with resistance after work in the evening) I went to family doctor to have full urinalysis and GC/MS confirmation run so that I could see where my levels were at.

      I tested at 19 ng/mL on April 1st. I continued working out twice a day and eating right up until Friday, April 8. These last three days I’ve been sedentary as I’ve read online that helps. My workout routine stayed the same through April 7. The cutoff for my drug screen today is 50 ng/mL. Should I be worried at all about my THC-COOH levels fluctuating that much that I could test over 50 later today? I know everyone is different but obviously I feel like I should easily continue to trend downward in that time since Friday, Apr. 1 if I had already tested at 19 ng/mL with a urinalysis showing my pH and s.g. are all in perfectly normal range.

      I’ve never been overweight (unless people count those BMI ranges to be an indicator of health, which, they surely aren’t in my opinion) and have always been an active person so just increasing that amount of activity as much as I did, I feel like it has to benefit me and that I was doing everything I could in the right way to help me pass this. I don’t know if THC-COOH levels can fluctuate from something like 19 all the way to 50 or higher. Being the worry wart I am, even though it was lab confirmed GC/MS through a Quest Diagnostics that my doctor ran, I just feel like it won’t work out for me for some reason.

      • Mary Jane says:

        Try to relax 🙂 best of luck

        • Mr. Mr. says:

          Had 20 days to not smoke. Took literally 15 home test, 3 different brands. Passed all 15. Tested at labcorp, came back dilluted. Took 2nd test, definitely yellow. Prior to stopping, smoked maximum a pinch 4-5 nights per week. Thoughts?

          • Mary Jane says:

            Hey Mr. Mr.
            Coming back diluted can mean more than just color. The tests also look for creatine levels, as well as, others. It’s hard to say, but I’m certainly rooting for you. Best of luck!

        • Olive says:

          Anthony’s comment on 4/11/16 sounds pretty similar to my situation which I have been shocked by. I’m small, not much body, have a fast metabolism and do about 3-5 miles/day worth of walking with my job (but it doesn’t include sweating). I’ve been a daily smoker of 1-3 bowls a day for years and is pretty potent for what we can get in my state(not CO or anything lol) I slowed down about 6 weeks out from suspected UDS, smoking a hit or two every few days. I’ve been completely abstinent for 14 days with increasing water intake to about 1.5 L a day, lowering fatty content in diet, etc. I’ve gotten 2 different brands of home drug tests. 1 with a 50ng/mL and one with a 20ng/mL. I took a few of the 50ng/mL tests 3-5 days after last use to check validity and had 3 positives(as suspected). On day 14 I decided to test another one, thinking to further validate it. However, it was negative! So I tested 2 more of those which also showed negative results. Even the 20ng cut off tested negative as well!!! Like I said, in shock. Also used known positive urine of someone else to do 1 of the 50ng results with correct results! Wow. Am I really below 50ng and 20ng/mL after 2 weeks!!? Any comments regarding this?

      I’m applying for a job and they drug test I smoke about 2-3 bowls a night to help me sleep
      I assume I’ll have a drug test end of next week sometime so 5-9 days
      I bought 500mg niacin and 6 gallons of water and 8 liters of cranberry juice
      Do you think I have a chance at passing?

      Well i tested my own self. Last time i smoked was July 27. i have been drinking only water and when i get the urge to smoke i drink water. Ive only been drinking water and taking B-complex once a day since then. Today which makes 10 days i bought an over the counter strip urine drug test and guess what it tested positive. I have another 22 days to come up clean. My solution is to test myself every 10 days until i come up negative and continue to drink water. Previously i had to take the same drug test for work and stayed smoke free for 30 days and only drank water, tested on the 33rd day and passed the labs drug test. Now that im out of work because of a medical treatment i have more time to consume water. I was guessing that it was pure luck that i passed but hey i passed. This time around im a bit more nervous because of the medication i was prescribed which was zyprexa for bi-polar. I dont recommend discontinuing any prescribed meds but because ive read that zyprexa may also show up as positive on a drug test and I really need to get back to work im staying away from the meds during this time. I will definetly comment at this site in another 10 days and let you guys know my results. Wish me luck

      Hi! I took at DT before & passed w golden seal & cayanne for 3 days. Worked out a ton, drank a bunch of h20 & took 4 aspirin the day of.

      I have a test again in abt 5 days & it will have been abt 10 days since I took a few puffs. I smoke maybe a few rips to a bowl abt twice a week but sometimes none at all! I’m using the same method but also bought synthetic this time. Do you think I’ll pass? I’m 5’4″, 120 lbs & work out daily. Abt 19% body fat & female. Prob is, Ive smoked more this time than last time. Do you think I should do the synthetic or use my own? Thanks!

      Sorry! Forgot to add that I took a drug store test & it came back double negative in about 2 mins. First response one. I’m still concerned though!


    • J says:

      Found out that I had a drug test in less than 24 hours. Much like the rest of you, I researched like crazy trying to figure out a way to pass. Here is what I did.
      1. morning of test at 6:00 AM. I mixed one packet of Sure Jell with one gallon of water and began drinking.
      2. Along with drinking the Sure Jell mix, I used Purity Labs USB, which is a bottle of 10 pills you take with a lot of water.
      3. Finished the gallon of water by 0700, had urinated twice by this point.
      4. Drank maybe another quarter gallon of water while driving to work, and when I got there. Urinated a third time at work.
      5. Took the test at approximately 8:30. Gave a mid stream sample.
      6. Got a phone call today telling me I failed

      My test was sent to a lab. I wish either I had taken a chance with synthetic, or I wish that I had not fallen in love with MJ years ago. Might be different for others, but that is my outcome. Just ruined a 13 year career. Good luck and best wishes all.

    • Anon says:

      So I smoked last night, and a few nights before i smoked quite a bit, plus i took two hits of dabs. How long naturally should it stay in my system? I’m 6 foot 170. Almost no fat. Any tips? I have a job interview (with drug test) this next week but i am broke. are there any home remedies i could try?

    • Richely says:

      Hey, I had a swab drug test today; Monday morning and I smoked on Thursday night. I’ve brushed my teeth 2-3 times a day, drank an excessive amount of water and rinsed my mouth with mouth wash right before taking the drug test. I’m praying that I’ve passed it. Keep ya updated!

    You said you passed a test using niacin… 10 days before. How would rate your usage? Low medium or heavy? Thanks.

    • Mary Jane says:

      Heavy. Like, too heavy. I broke out in hives like crazy. I think I was taking something like 1000mg every couple of hours. I did this for a few days. It was a terrible experience, but it did seem to help. I guess I’m still on the fence with niacin. I wouldn’t trust niacin alone. I hope this helps. 🙂

        Your marijuana usage is heavy? Sorry, for the confusion.

        I havent smoked for 23 days. was only having a couple of cones each night to relax. I was taking Golden Seal three times a day for a week, and am now on a Detox Kit from my local smoke shop. I’m still testing positive! I have been sweating profusely from exercise before each shower, and following all instructions, but I can’t seem to get a negative test result. If I am negative after this week-long detox kit, how many days should I wait to do the drug test? I dont want them to know that I have been detoxing. the last tablets of the detox are Vit B complex and Creatine.

    • Mary Jane says:

      I still have mixed feelings about niacin. It doesn’t hurt, but I wouldn’t trust it by itself. I wrote a bit more on the subject of niacin in the article. I would definitely love to hear from some more people who have used it before deciding how good it is.

              • Charles Farley says:

                Niacin supposedly causes the body to flush toxins through the liver…the net result is the THC ends up lining the bladder.
                my understanding, and the method I’ve used in the past is to add Soy Lecithin capsules into the mix…what this is supposed to do is provide a fatty acid for the THC to bind to (similar in concept to prepping butter or vegetable oils when cooking with weed). so the theory is the niacin flushes the system, and the soy lecithin provides the fatty acids for the THC to bind to so you can pee it out of your system while drinking a ton of water.

                I’ve done this before combined with a “detox” masking agent with less 48 hours notice before a new hire drug screen more than once with out issue.
                I’m 6’4″ weigh about 185lbs, and tend to smoke 1-2 pinches per day every day for years.

  • BrownieSundae says:

    I am currently doing niacin, eating clean, lots of water and tea. Hope it works I’ll be testing myself before I go and substituting if not. I’ve used two containers for this either breast milk storage bags because they are triple sealed and have a pout spout and lay flat against your leg or a travel size mouth wash bottle I like the bottle better because it doesn’t crinkle I get nervous someone might hear the bag . I always wear spanx to help with the temperature and if you have seat warmers in your car that helps get you a little hotter down there than usual. I keep it in between my legs no need to hold it inside of you. I’ve passed over 5 times substituting never had a temperature issue.

    • Mary Jane says:

      Great information. Thanks for sharing. It seems you do the right thing to prepare and test yourself beforehand. I like the spanx idea. Best of luck on your upcoming test.

    Oh and also i took a dollar store test sunday night and passed it, and after the test i cut it off and finished at home with another dollar store test and passed that as well. And i broke the red tape over the bottle with my sample in it while no one was looking lol, i think that means they cant even test it idk, this is a military battalion piss test so i think it goes to the lab!

    • Big D says:

      Did it work? No one ever writes back and tells what happened….sad

    • LISTENUP says:

      I’ve been scrolling through and enjoying these comments. I highly recommend more of you spend the money on home drug test. 20$ is completely worth not losing a job or getting a job etc. I’ve tried many a methods and the dilution is the best. I currently am a firm believer of the surejell/Certo. Certo is liquid and much easier to stomach than the powder. 320z Gatorade and the whole packet. Drink it whole immediately. The Gatorade just makes it easier to drink. Follow it with more water until you have to pee. Get in maybe 2-3 pees before you put it in a cup and always go midstream. So my deal is I went about 45 days of heavy use. Went cold turkey and on day 12 of no smoking I took a home test without doing anything and failed (of course). 2hrs later I took another one after the surejell and low and behold I passed. Not like barely it was a distinct clear negative.(2 red lines) so if you’ve made it this far on my long comment I’ll address the remark about the red tape if your military. Military drug testing is all about chain of custody. When you are done providing the sample and you red tape it, initial it then place it back in the box you are no longer responsible. So if you manage to break the tape without anyone noticing and get it in the box, When that sample is pulled and inspected they will see that it has been tampered with and it will not be tested. There is no investigation on who and how it was tampered because they deal with 1,000s of samples and frankly it’s not there job. You just dodged a bullet, I’ve done this a few times. Also a common misconception with military testing is that they test for anything other than a drug. THEY DONT!! I’ve placed water in a bottle before just to see what happened and nothing happened. Military testing is meant as a deterrent, and to potentially catch heavy abusers of any drug. We’d all be foolish to think that 100% of the military is drug free and furthermore that people don’t find ways to get past drug test. Lastly the best way is to not use at all. Good luck

  • Anonomous (Thank you Mary says:

    I have to thank this site because it was very instrumental in giving “real” recommendations on how to pass a test. I used them, I hadn’t smoked in 30 days but I took a store bought test from CVS and failed on day 30 !! , I was sooo nervous the test was the in 4 days ! The problem was I used my first urination of the day !! After reading Mary Jane’s Diary, i found out that you NEVER use the first and should try to pee 4 or 5 times before the test. Armed with that information I ran to the store bought a gallon of water and pure cranberry juice and began to hydrate. knowing I had a couple of days I drank a gallon every day, but on the night before the test, I only drank 2 liters and took 3 B12 pills. I drank coffee that morning and pee’d 4 times, When it was time I took the middle stream not the first pee, and 2 days later passed with flying colors !! Thank God ! I was soooo relieved. Thank you Mary Jane ! You provide and invaluable service !!

    • Mary Jane says:

      That’s awesome! I’m so glad the article was helpful. Also, that you so much for coming back and sharing your experience – first hand accounts are invaluable! Cheers 🙂

  • Lucy says:

    Niacin works…i am a medical assistant and went for a job at a clinic…they did urine testing. I stopped smoking two or three days prior to the test and started popping 250mgs Niacin tablets (about 3 or 4 a day one or two during the day and before bed).Between the niacin and LOTS of water…i passed. Drink cranberry juice a few hours before the test to help with the color…or i hear B12 does the trick too. I also used the slow release niacin before…but you have to do that over the period of a week or so. Taking a hot bath or shower will help open the pores and release toxins…hope it helps

    • Mary Jane says:

      Thanks for the input! How much discomfort did you experience from that dosage of Niacin? Again, thank you so much for sharing 🙂

      • Anonymous says:

        I took niacins before and I was a heavy smoker, like 5blunts a day of kush. I only took them the day of and I took like 1500 mg and I was hot n red n itchy. I passed but my friend didn’t pass it just lowered levels. We was getting tested everyday for drug court. I started Taking certo and I passed with that to. I drank it in a 20ounce bottle cranberry n that another bottle of cranberry and it worked but one time I took it with just one bottle and it didn’t work but I was a heavy user. I suggest u do several methods, palo tea, a couple niacins n certo just to be safe and u should be good! Good luck

    Hi please help!

    I’m a very infrequent smoker. I only smoke a bit when I’m with friends every now and then.

    I had smoked Thanksgiving night and had a unexpected lab blood test done on me at work!

    I didn’t smoke for about 5 & 1/2 days

    Again I don’t smoke every single day, I’m 6’1 around 220pounds

  • Ashley says:

    I’ve used niacin when I was younger. I was a heavy smoker and was smoking up until the day before the drug test. I took niacin within a few hours of the drug test. No one told me that you’d burn like crazy so my dumb ass was on the phone with poison control lmao! But yeah, I passed with just taking the niacin that one time and not even flushing my system with water.

  • Norri says:

    Hi there. I’ve been clean for 22 days, before that I probably smoked about 1-2 bowls of good stuff a day. I’m 26, female, 5’5″ & 123 lbs with a pretty fast metabolism. I had a test/screen last that will be going to a lab (the place uses quest and labcorp, so I don’t know which it’ll be). I’ve passed two First Check tests with a decent line both times, Tuesday & last Saturday. I bought certo and gatorade, and drank that along with a half gallon of water about 3 hours before my test-my pee was clear. I always eat a ton of fruit and veggies, can’t remember the last time I had fast food or anything like that. Oh and I’ve been taking metamucil 3x a day for a week as well as tablespoons of raw applecider vinegar regularly (I know vinegar doesn’t do squat, but I drink ACS regularly no matter what so I thought I’d share). I ate some asparagus and carrots and drank a monster to help color my urine and also took a multivitamin, it ended up being light yellow for the test. Any thoughts on how this is going to go down for me?Obviously I’m stressing hard like everyone else that scours the Internet for answers. Thanks in advance

  • Spock's Brain says:

    I have a test coming up in roughly 3 and a half weeks. I stopped smoking 30 days out. I’m excercising and trying to keep fats out of my diet. So I’m taking all the proper steps. Couple questions.

    Does sweating in a sauna have an effect on flushing it out of your system?

    And secondly, with niacin, is this something that you use a few days before the test or is it something that you use to aid in helping flush the metabolites out of your system?

    Got a 12 pack home test on the way from amazon, so I’m going to be using to see my progress, as seeing results with dilution.

    • Olive says:

      Mary Jane, I need help and your opinion sounds like the help I need! Okay, so I am a 93 lb female that does not work out but I do walk 3-5 miles daily at work. I drink mostly water, but do not gt the daily recommended amount. I have been a daily smoker (about a gram of kush a day) for years. I have 46 days until a suspected urine drug test. I do plan to increase water intake a whole lot and addniacin to my regimen and sweat lol
      Already take b12. Do you think I have enough time to completely detox? I have test to check along the way and also will probably take clean piss but I don’t know if they will watch me or not (it’s for school). We all know that we don’t want our relationship with Mary jane to end. Also, Do you think I could possibly go a wee bit longer if I greatly decrease consumption? (Like a hit/day or every other day) THANK YOU for all the info u have already given

      • Mary Jane says:

        If you know you have a drug test then I would quit smoking right now and wouldn’t push it. I know it’s tough, but it’ll be worth it in the end. I have an article about tolerance breaks that may be helpful. Best of luck.

  • Spock's Brain says:

    Also one more thing. What is the proper amount of cratene to take when you’re using it to suppliment for dilution? I see dosages of the b12 always stated, but nothing on the amount of creatine.

  • Spock's Brain says:

    Another thing I thought about to consider is when working out, lifting weights is good to combine with cardio, as lifting burns fat for days after you do it as it repairs the muscles. But another thing to keep in mind with this is I plan on stopping the lifting about a week prior to the test instead of 72 hours, because of this very idea. The whole goal is to add fat in those last 72 hours, and if you’re lifting up until that point, it will cause your body to burn fat through those last 72 hours. Just something to keep in mind.

  • Ray says:

    Great read!

    Wondering if waiting around in the waiting room before the actual test will affect the dilution. How long after the last urination will it stay clean? Ive heard if people waiting 1 hr to 2 hrs

  • Desperate Stoner says:

    I have a pre-employment test for a new job coming up in approximately 10 days. Prior to that I had smoked a few times, a bowl or two, prior to and after work which is a physically demanding job so I am sweating and moving around. I also intend of working out and exercising over the holidays, but my concern is whether or not I will be able to successfully dillute if I abstain for the next 10 days.

    My worries about trying replacement is that I am getting a physical and drug test so I don’t know if I’ll have to strip down or not.

    I’m 6’1 and about 220 pounds (Average body build, not overly fat, but do have some pudge). Think there is any hope?

  • Spock's Brain says:

    Just an update. I tested negative with dilution after 10 days. I’m still testing positive at 15 days without the dilution. Would like to not rely on dilution as much as possible, but at least at this point I know I’m testing negative with it. So that’s a good thing.

  • Spock's Brain says:

    I have a question. I think I’m now slightly passing without dilution. I’m getting two lines, but line indicating negative is very faint. Is that still considered a pass even if it’s a faint line indicating I passed?

    Got a drug test Monday first time I smoked was 15 days ago did a 7day detox lots and Loto of water and cran juice and took 3 at home drug test 20 bucks a peace and passed all 3 with a faint line do I need to be worried and I do not work out

  • Lee says:

    Thanks. Great article! About the only thing I can add is Golden Seal and Dandelion are good blood detoxifiers. And Milk Thistle is a good liver detoxifer. I can’t say they will help pass a drug test but they can’t hurt.

  • Lee says:

    Let me add the best way around employment drug screening is to get the laws changed. This is a privacy issue that is protected under the 4th Amendment. Employers have NO right delving into your personal life! This is becoming more of an issue in states that have legalized mj. In fact, there is a case right now in the Colorado Supreme Court challenging this issue. If it is successful other states will be taking notice. Also, there is a new breathalyzer in development that will test current THC levels in the body. This new test wiil be cheaper and more readily available and reliabe for ememployers to enforce their drug policies. With this test there will be no need for lengthy and expensive detoxes. Just don’t smoke before you go for the test.

    Yo, I have to take a drug test before I can get my driver’s license. I weigh 85kg at 1.90m, and have a really low amount of body fat and an ass whooping metabolism. I don’t exercise much but I’m a pretty active dude. I’ve been smoking heavily for 3 years now, on average about 4 grams a day, 20% thc. The week before new year’s eve I was only smoking oil, after new years eve I stopped for a week, smoked a blunt the sunday before last and then stopped again. Would I pass if I took the test next week? Or should I wait it out? I want to pass the test on my 1st try, if I fail shit’s going down. However it’s best for me to get my license asap. Niacin is sadly not readily availible. I mainly drink milk, orange juice and tea and my diet ist mainly asian, as in indian, chinese, vietnamese, korean. I’ve also heard that drinking about 2 liters of milk a day helps :’D Not sure how much I should believe in that.

    I’m 5’5 and 250 ish pounds. I have a pre employment drug test in about 6 weeks from the day I stopped. I stopped drinking sodas and eating fats. I’ve been drinking at least 4-5 (going to try for more like 7-8) water bottles daily and I started running yesterday- I ran about half a mile yesterday and will continue building up to a mile in the next few days. I’ve been eating more healthy and balanced meals.

    I’m only worried as I am very chubby!! Anyways please give me any extra advice or tips, and do you personally think I’ll be okay in 6 weeks?

    • Hope says:

      I also forgot to mention that I smoked small amounts throughout the day and night, daily for about 2 months, so I wasn’t a very heavy user, I probably smoked like 5 grams or so the last 3 weeks that I actually smoked. Thanks !

    • Mary Jane says:

      Six weeks should be plenty of time. My best advice is to stop by your local pharmacy and pick up a test kit. Try it out a week before your test.

    I have. Urine test coming up in a week and 2 days. I’m a heavy smoker( eighth a day) but I quit two days ago.

  • Pancho Villa says:

    Hello Mary Jane and drug test passing community. It would be very helpful if someone reading this that can relate replied.

    I smoked the last 3 days, like 3 to 7 drags from a joint a day. I had been 3 1/2 months without smoking. So there is my first question. Does the 3 1/2 months put me in a benefitial position? Like the guys who had never smoked ( since I was completely clean before smoking?)

    I have random drug tests performed, so I dont know when its my turn, but I will have at least 7 to 10 days. I would be awesome if you made like a section of help and tips for guys who are having random tests, since the are non in the internet.

    I will be trying the dilution method, and doing exercise almost every day of the week. I have fast metabolism and Im slim as well. I will also buy the home kit for testing. What more could you recomend??

    Thanks Mary Jane

  • Pancho Villa says:

    Also does it matter if I drink lots of water and the stuff you recomended 20 before the test or is it just important a few days before the test?

    I’m a really heavy smoker. I have a drug test coming next week I don’t know the exact date it could be Monday. I bought some niacin 250mg and will start drinking plenty of water (4-5bottles) Do you think it will help if so how much should I start with? I’m around 5’2 240lbs.

      Niacin has shown to be somewhat helpful, but don’t depend on it alone. Use the recommended dose on the bottle of niacin you bought. I would pick up a test kit and check yourself at home before going in for the test.

    heyy , i have stopped smoking ten days ago and i ate lots of garlic two days before the test , my test was today will i pass the test plz reply as fast as u can :s

  • Kris says:

    Hey Mary Jane,

    I just recently took a random drug test and I fear it may come back with a positive result. Over the past week I have been drinking Liter water bottles, some exercise, and eating healthy. I am about 230lbs.

    I went an took an at home drug test today and it came back positive STILL. I have about 24-48 hrs at least before the possibility of them retesting me. If they retest me it will most likely be monitored. What are my options? Advice?

  • Anonymous says:

    I’ve used palo azul…and I still do the problem is people just do it wrong you have to drink 1-2 gallons depending on your weight and twice as much water. This is the method I used to get into the military 8 years ago and I use it for probation now, I’ve never failed a drug test but I do recommend exercising as well. Supposedly the tea will keep you clean permanently, however I always end up smoking after my tests lol I hope this is helpful for you guys

  • Andrew FAKE NAME Scott says:

    I have a Drug Test Tomorrow, and looking for advice. I’ll try and be as clear as possible as most of these forms lack some details, and some people may benefit from the added story line.
    I have to take a Express 12 panel test with a 50 ng/ml cut-off apparently, its pass or fail with no lab screening. I quit heavy usage about 29 days ago (2 to 4 bong hits of somewhat good weed a day, not kush), but have taken 4/5 bong hits total in between as I got a cold and needed some relief. My last hit was a small bowl mixed with cigar 5 days ago. I’m 5’9″ and 150 pounds with a bmi of 22, I’m fairly active, and would consider myself to be above average for fitness. About 14 days ago I started to drink about 8-10 16oz glasses of water and pee at least 10 times daily. This deff flushed my system as I felt tried and drained of nutrients with in the 3rd day. As well i’ve been using about 1000mg of Niacin daily followed with zinc supplements, as I read a article about zinc combining with the metabolites. I also have been taking a stress related multivitamin that is high in B12 vitamins. I don’t work that much in the winter, but I do at home push ups and crunchies. My test is at 3pm so I plan on using the dilution method and drink coffee and water before as well as pee at least 5 times. In Canada you can’t just buy test strips at a drug store you have to order them online, I live in a bit of a isolated area so getting one would of taken nearly a week so I didn’t bother. I was wondering what kinda chances I have to pass, by reading forms it seems that some people can pass in 3 days others 3 months.


      So a no go on the test for me today, Surehire test procedures are strict and I failed, even at 50 ng/ml. I tried using a detox called (xxtra clean) because I was freaking out, followed the instructions to a T, empty stomach, 2 hours before, chugged the bottle then drank 20 more oz of water at a reasonable rate, 3 pees before hand etc. I guess I was just too much of a daily user to pass. I was told that there are some places that only do drug tests and that they rely on repeat business so they tend to pass more people even though they shouldn’t. The place I was sent to only does a few of them as they are regularly a physio therapy clinic they have no reason to alter the results (contracted out by Surehire when needed as I live in a remote area). My work is giving me another chance next week and that will put me in the 10 to 11 day range from my last puff, since my stomach dropped and I threw up on the way home, I’m hoping this is enough time as it will put me over the 30 day mark for regular usage but i’ll still be under the 21 days the Doc at the client told me about last use. Also good luck subbing for surehire tests, the guy stays in the bathroom, you get a stall but if you were fumbling with anything he would know.
      To end, I’m going to say that Niacin is probably more of a myth from my experience, as I was flush red every day for 5 days, the zinc crap I bought didn’t seem to help but gave me a metaly taste in my mouth?, the detox stuff is as thought only a expense dilution method.
      I’m going to try the working out method now till then but I’m really feeling pretty down. To all those that can pass in 48 hours I’m truly envious.
      Hope this Helps someone, I will report back if I pass my next attempt with similar detail.

      • Mary Jane says:

        Thank you so much for providing an update. I’m sorry to hear you failed the test, but that’s great that your job is giving you a second chance. Best of luck, always.

  • Bonesy says:

    let me preface my story with the fact i am on random color calls for probation. had a dirty ua on january 3rd, just couldnt dilute it enough. was a heavy, heavy user. ten days later after going from all day to once a day my color was called and i gave another positive diluted sample. fast forward to february, i have finally got past my heavy use and heavy thc stored in my non existent fat cells and i finally gave a baseline clean ua. like a jackass i celebrated with a bowl, i am still weaning and weaning from a g to half a g, im down to a god damn pinch a day. fucking ridiculously weak at this quitting and not going to prison. even with the risks i still suck at quitting… well tommorow is the last day of color calling for the week and then a weekend of further exercising and guaranteeing i can be clean for the upcoming week.

    weigh about 120 lb, 6ft 3. male, low activity – work a corporate desk job 10hrs a day.

    im going to buy a jug of some cranberry juice and a few gallons of water. ill find out at 5am if they will call my color and will have to report between 8am-12pm.

    think i should buy a detox drink in addition to the dilution i am trying?

  • Trying to Pass says:

    I need to pass a test in 2 weeks exactly I’m a heavy smoker like one day I’ll smoke 4 blunts and one day I’ll smoke two but it’s a every day thing I’m 5’7 and I weigh 155 I work running around a deli/bakery at least 5-6 days and have 2 kids ages 2 and 1 they both walk and run so I’m constantly on the move with them I don’t have best eating habits due to stress but I drink water on a regular I have niacin pills please tell me instruction on the best results please and thank u

  • That Dude says:

    To the point:
    I am 6’2 190 lb male. last time I smoked was friday february 12th at night. I have a probation UA tomorrow February 16th in the late morning. I believe it is called a 4 panel test. immediate results. Prior to smoking friday I smoked two days before that. overall i have significantly cut down my smoking.

    I purchased a bottle of Advanced Detox Solutions Ultimate Cleanser drink. I will drink the detox 3 hours 2.5-3 hours before my test tomorrow. along with heavy water drinking tonight and tomorrow morning, anything else I can do?

    Should I stop worrying so much if I follow the directions or should I be worried?

    I truly do appreciate this forum due to all the crap sites out there with nothing but ads and trollers .

    Thank you MJ Diary!

    • Mary Jane says:

      Make sure you follow the instructions on the ‘detox’ exactly. If you can grab a home kit, it’s nice to test yourself before going in. Best of luck. Let us know how it turned out and which drink you used.

  • kushgirl says:

    I have to take a blood test either Thursday or Monday im extremely nervous because ive been a heavy weed smoker for about 6yrs im 5’3 and 100 pounds can u offer me any advice

    • Mary Jane says:

      My only advice is to make sure you stop smoking now. There really isn’t any quick tricks for blood. The good news is that THC doesn’t stay in your bloodstream for nearly as long as it does in your urine. I don’t know if exercise necessarily helps, but I doubt it would hurt to get your blood circulating. Let us know how it turns out. We’re rooting for ya!

  • John Doe says:

    Hey Mary Jane, Awesome website. Definitely one of the best on the subject I have seen! Thanks. I work in construction and have to take urine tests about 3 or 4 times a year. (Fuckin fascist cunts!). I always use the replace method which works really well if its just for employment. I don’t generally have anyone I can get clean urine from because most people I know and work with smoke. I have always been weary of synthetic urine for obvious reasons but I just wanted to let you know that there is an alternative, it’s called powdered urine. PU100 to be specific. Real urine that has been made into powdered form. Just add water and your good to go. However I do want to make it clear as you have said that getting your temps right is crucial. I had a friend who got popped recently because the hand warming pad it comes with was no good and only lasted an hour instead of the six it was supposed to. His urine was to cold and he got straight busted. Shame too. He was a good guy, great worker, smart, never high at work. So be warned, buy extra hand warming pads. Keep up the great work.

  • Mr Nice High says:

    Great info MJ..I have an interview coming up..if I am offered the job I will then have to take a urine test but I’m not sure when yet..I haven’t smoked since last Friday so between then and my interview will be 11 days..I’ve been drinking about 96 oz of water per day and been peeing frequently..especially in the middle of the night..I’m leaning towards purchasing niacin but also thinking about purchasing synthetic urine in fear that my urine may not be clean yet..which route do you think would be best?

    • Cheryl schmied says:

      How does swishing listerine in ur .south. before a test help.w passing and w all the water I’m drinking to.rid the thc should I add turmeric a few days before the test as to the urine won’t look so clear and diluted? Just a thought.also I bought a masking drink but 2 days before my test started taking 2 b 12 and a multi vitamin a day lots of cranberry juice , sucking alot of water. It’s been 22 days since I last smoked. I did buy a thc drug test. Any other suggestions . I’m afraid of niacin reaction . If I have a reaction, don’t want them to think anything’s up. Can’t get any cretenon. I’m 5’5″ 190. Should I take the detox masking drink asit’s called. I remember mid stream a d should I drive k cranberry.and water morning of too. P)essentially help. I must pass this test.

  • Brinden says:

    I’m a male 6ft 215 pounds prolly 15% body fat. I was clean for 2 months, then smoked 1-3 hits a day for about a week of potent. I have a test in a week and have quit, started the diuretics and will take a detox kit the day of ,along with the dilution method for the full 7 days leading up to the test. The test is at a lab for hospital job. What’s your confidence level?

  • Nicole says:

    Okay so reading through the comments I’m kinda of confused. I last smoked January 29th.before that, I didn’t smoke since October. Before that, I didn’t smoke since April. And before that, I didn’t smoke since November. So I’m a very infrequent smoker (and when I do smoke it’s maybe 4-5 hits at most). I leave for MEPs in 2 weeks and I’ve been drinking a lot of water and cranberry juice but I’m confused at how working out can higher the THC levels? I’m confused… Should I be exercising more or less? And what are my chances of passing? Thanks

    • Mary Jane says:

      I would say that as long as you don’t smoke any more you should be fine (of course, no guarantees). You should be exercising up until 72 hours before the test. Once you’re within 3 days of the test stop exercising. The idea is that exercise releases THC from your fat cells. You want to get rid of as much as possible, while still trying to maintaining the lowest level possible at test time. I hope this helps.

  • Linzy Louden says:

    Hello! I have a blood test coming up Thursday morning and today is Tuesday. I haven’t smoked since Sunday night, but I did smoke about 8-11 bowl packs between Friday-Sunday, and I didn’t smoke for about 5 days before Friday. I bought one of those detox drink things I was going to take today but I’m still not sure if it would still be in my blood or not. I just want to know opinions if you think I will pass or not?

    • Mary Jane says:

      The detox drink won’t do anything for a blood test. The good news is that THC doesn’t stay in your blood stream nearly as long as your urine. There is a decent chance that you’ll pass, but I can’t give any guarantees. As far as I know, there are no tricks for passing a blood test. Let us know how it turns out. Best of luck!

    I previously failed a drug test for probation on 1.28.16. I smoked everyday from 1.28.16 to 2.15.16. I have a court date on the 29th at 8:30. I spoke to the pharmacist at cvs, the recommended niacin. I have been working on since Tuesday. Burning 400-600 calories. Is there anyway to pass the drug test? I am not trying to go to jail. I’m frightened.

    Also, I’m a female 5’3 172, slow metabolism. But I have been sweating like crazy. I can’t use the synthetic method.

  • Sedric W says:

    Good way to pass Siliva test is wash your mouth out with Hydrogen Peroxide right before test. It will make ur mouth a little dry but I’ve used this several times, I smoked on the way to the interview and used this technique right before I walked in the door and got the job

  • rpjr59 says:

    Im a truck driver subject to random test Im 6’3-315 bs had not smoked in about a year or so but at xmas i gave in and smoked a 1/4 over a 2 months time I have been dry for 9 days now,I drink a lot of water on a daily basis. I can pass a over the counter test but can i pass a lab test.

    • Mary Jane says:

      The over the counter tests are the same ones that are used by most labs so you should be fine. Just make sure you don’t over dilute your urine with water. You have to have the right levels of creatine and such. Best of luck.

  • Heavy smoker with pending test says:

    Hey MaryJanes Diary…Great site and thank you for all of the info. Sorry for the novel level of a post but thought the more info the better for everyone reading. Here is my situation and any input would be appreciated.

    I stopped smoking on the evening of 3/2/16. I was smoking about 1-2 grams of high grade THC bud and 1-2 hits of hash oils everyday for the past 6 years with a 1 week break in Dec 2015 and then back at it until 3/2/16. Upcoming UA for a position with a company that mainly does projects for the gov’t so I am kind of concerned about having an observed UA take place even though it is for employment. I am 6’2″ 160 lbs with low body fat, I live an active lifestyle with 4-5 workouts a week and eat healthy with maybe 1-2 high fat meals a week.

    Since stopping on 3/2/16 I am trying to do everything I can to avoid attempting the substitution method with maybe being observed on the test. I have been doing 2 workouts a day (1 hr of hot yoga in the morning and 30 min lift / 30 min sauna session at night). Each day at a minimum I drink 16oz cranberry juice, 16oz coffee, 24oz water w/ 1oz of lemon juice, 16oz green tea, 16oz dandelion detox tea (2 tea bags), 20oz water with scoop of no fat protein powder for post lifting workout, 80oz of standard water, and 12-24oz of craft beer. Some days I will drink more but this a minimum list of my consumption. I have cut out fatty foods and eating basically vegetarian/vegan until 3 days out and will start eating fatty foods as you mentioned in a prior post. I am picking up Niacin today and adding that to

    I have take home kits and to no ones surprise I failed this morning. Not sure when the exact date of test will be but I know I will have a 72 hr window to schedule the UA and will stop Niacin and switch my diet/exercising routine at that point. My best estimate for the date of the test will be during the week of 3/14 – 3/18 unless I get lucky and it is during the following week.

    I am planning on doing the dilution method on the day of the UA and plan on testing myself at home with this method when I know that I am 72 hrs out from the UA. Is that a good idea? What should I add/subtract from my current plan to increase my odds of passing?

    Thank you for your input

  • CollegeGrad says:

    I recently accepted a job and have no idea when my pre screen test is. I stopped smoking 12 days ago but wasn’t a heavy user. Only problem was I did a dab (higher THC).

    I took a 5 day detox supplement by rescue detox, have been working out and chugging water. Big issue is, I now fear that the 5 day detox is not a permanent solution.

    I could have a week or a month before my test. I’m curious of the best thing to take (niacin, cranberry, tea, etc) to accelerate the NATURAL process.

    And if I burn my system out with niacin now, will I still pee clean 2 weeks later?

    Thank you

    • Mary Jane says:

      You can go ahead and start using the niacin. Make sure not to use to much at one time. It really will burn you like crazy. Make sure to look over my sections on when to work out and also dieting. Get you some test strips just to be sure. Best of luck!

  • Big D says:

    It seems every drug test you buy online or in the store for THC always shows a very faint line on the second line….The directions say if it is a faint line it is negative but do you know of any that show a good dark line when negative? Having a faint line makes me think it is positive, whay do they always show a faint line on THC but a dark line on all others? seems like someone could make a test that is either a dark line or no line….

    • Mary Jane says:

      THC tests work on a scale. Basically, you can technically have a very small amount in your system and still be considered negative. Don’t worry. A faint line is every bit as negative as a super dark line.

    • Tiny Tim says:

      I get really nervous about this too…. but have personally spoken with a few different home test manufacturers and they all say the same thing… any line, no matter how dark/faint/wide/thin/etc etc is still considered a negative (pass). It must have something to do with how the metabolites interact with the test strip, because it seems to be a fairly frequent question.

      They also mentioned to take a picture of the test strip after the 5 minutes is up. If you snap a picture and can see the line in the photo you are good…. something to do with your eyes playing tricks on you, especially if the line is very faint.

  • Kitten says:

    So, I don’t personally smoke, however my roommate does. We live in a small house. He usually tries not blow his smoke anywhere near me. Considering I leave in 25 days give or take for basic training. I will get tested at MEPS before going to the base. He doesn’t smoke to heavily while Im there and tries to ventilated the air in the house better when I am. I don’t know if I can fail from simply having secondhand smoke….? I also have been wanting to smoke on last time before leaving. I haven’t smoked since 2012… Im 5’3″ 115lbs.. I don’t want to get baked just like 2 hits that’s always been enough for me. I exercise a little bit and drink plenty of fluids all the time.. I took the niacin once and ended up not having to get a test but I can vouchee for the redness and burning I took them the morning before I was supposed to have my test.. did not know it would do that and it started burning and I was red from head to toe while getting a tattoo.. so embarrassing.
    Any suggestions or comments about the second hand smoke because I’ve heard that alone can make you test positive and heard it wont?

    • Mary Jane says:

      You’re going to be fine. If you want some peace of mind just go pick up a test kit at a pharmacy and check it out. Best of luck in your training. Safe journeys my friend!

  • Anonymous says:

    HELP! I haven’t smoked in 8 weeks and 2 days. I consume mostly water when at work(40 hours a week), drink beer on a daily basis, and work out 3 times a week. I am on probation and have a piss test in 10 days. I’ve taken 2 at-home dip tests and somehow am still showing a positive for THC. I weigh 150 lbs and my metabolism is pretty high. I was a heavy smoker previously but, have avoided all contact with it since being on papers. Don’t understand and curious if anyone has tips(other than the obvious ones stated) or a similar story to share. Really getting stressed from this.

  • Tiny Tim says:

    Just wanted to share some personal experience with everyone. Previously I have used QuickFix 6.1 synthetic urine and passed two pre-access (unsupervised) tests, but the last time I tried to use it, I was failed before the sample was even tested. The tester took the sample from me, swirled it, smelled it, and with a huge grin flushed it. She mentioned that urine that colour typically had a smell, and this had none, so I was going to have to re-test. I’m thinking that I made too much noise and was screwed before I even walked out of the bathroom. The key to subbing is practice, practice, PRACTICE! You can use plain water at home to ensure the temperature stays within range and that you can get the stashed sample into the cup without making a bunch of noise. Personally, I would try and find a clean donor or use powdered urine because both will have the same characteristics of your own urine. The synthetic stuff is lab-created and doesn’t produce the same smell or colour as normal urine, and doesn’t foam as much as it should when it is poured.

    • Mary Jane says:

      Thanks for the info. What a weird technician to smell your urine. Like, who does that?

    • Rambler says:

      Tiny Tim, I had an exact carbon copy of that experience in the northern Denver area: the swirling, smelling, dumping, devilish grin, retest, and horrible consequences. Not trying to bum anyone out, just trying to be constructive. It’s no big deal if you know the environment you’ll be testing, but I think the sound gave me away too. Used to be my go to and I’m not super gunshy on synthetic urine.

  • Tiny Tim says:

    As for the dilution method, you need to give yourself as much time as possible and don’t rely on the “detox” drinks. The only reason people claim they work is because of the amount of water you need to drink with them. Again, the key is to practice at home prior to your test.

    -Use sports drinks and/or energy drinks to dilute your urine. They will increase the specific gravity of the sample and give it back some yellow colour… glowing neon urine from too many vitamins is bad! As long as you aren’t pissing straight, clear water, you should be within the SG range.

    -Start loading up on creatine monohydrate in the days before the test and don’t just rely on eating red meat. You’d have to eat pound after pound of raw meat for it to make enough of a difference. There is no upper limit for creatinine (the metabolite of creatine) in urine, but anything under 20 mg/dL is considered dilute.

    – Don’t worry too much about the pH of your urine. This is usually tested to see if the sample has been tampered with after the fact. The pH range is pretty high, so as long as it comes from your body, you should be fine.

    – Instead of just using the dipstick tests, try and find something called an iCup or NxCheck test cups. They can be found online and are the same basic test they use in any pre-screen or express test. The dipstick tests are easily fooled by drinking a whole bunch of water, but that doesn’t mean your sample with pass the adulteration tests (pH, SG, creatinine, adulterants). The cups have these adulterant tests built in, so you can be much more certain if your dilution method will pass a lab test.

  • donni says:

    I had to pass my employment drug test about 6 months ago, and I passed even though I smoked weed like a week before i found out. Here’s what I did to pass: (1) drink plenty of water and (2) take the Dr Max Powers 15 Days Cleanse (I only took it for 6 days) and I passed the Labcorp drug tests. All clean!

    • Lakin says:

      I am extremely curious are you a heavy user or just occasional? Did you work out at all? Also sorry kinda personal question but how much do you weigh, do you have a high metabolism? Whats your diet like? I am thinking about trying the Dr Max Powers since it worked so well for you. Need feedback soon! thanks!

  • Gary says:

    I need someone’s help. I have a drug test this upcoming Thursday. Last Friday 3.11.16 I smoke .5 of exotic/loud. Didn’t smoke the whole week until thursday 3.17.16 I smoked about .7 of exotic/loud. For some reason I always have a low tolerance. So when I smoke I take 2-4 hits. And I’m curious about if me having a low tolerance would help detox faster if I stick to working out and eating foods that boost metabolism and burns fat

    • Mary Jane says:

      Smoking less would certainly help you detox faster. Make sure you stop working out 72 hours before the test. Consider using the replacement method – it’s my favorite.

      • Dont matter says:

        Best way to pass regular PRE employment urine test or urine test period.
        Detox dont work is all money making for them, fake urine is risky and expensive.
        No matter how much you try to stay sober, drink water or wuteva, exercise and sweat depending on the person body and metabolism THC sticks to your fat cells and urine like super glue even if you are skinny you have to be sober for many months so dont waste your time.

        I have pass 12 times already over the years with no problem I gotten so good I even smoke the same day of test to laugh at the system lol.

        Just use a friend or family member clean urine, different gender, pregnant or not dont matter they are only testing for the presence of drugs, the urine needs to be human no animals please, is always better if the person drives with you find and stop at a bathroom somewhere near the test site to pee in a empty clean 5 Hour energy bottle needs to be completely fill. If your friend is a girl have her peen in a clean paper coffee cup so she could have better Aim and then pour it inside the 5 hour energy drink.

        Next attach 1 hand warmer with rubberband not 2 hand warmer since sample might get to hot. Put in a baby sock or small sock so the hand warmer doesn’t burn your balls or vagina cus it will hurt.
        Use really tight boxers or underwear and put it in the space between your legs. If the person cant drive with you, you have 2 to 3 hours the most before the piss is not good anymore. For this case use 2 hand warmers the key is too keep the pee warm regardless having it between your legs helps to keep it warm also.

        By law in any state NO one will go to the bathroom with you or touch you there normally sometimes they check the shoes and pockets but that’s it. as soon as u get in the bathroom put the pee in the cup fast and gentle and then put it back between your legs and then Pee on the toilet dont EVER flush cus they will ask to do it again also make sure the pee you borrow is yellow not clear I always tell my friends to drink coffee before. Make sure the 5 hour energy is tight and not spilling. Walk normal and with confidence they check if the person looks or sounds nervous.

        Also if you have a physical at the same time they make you pee first most times and there always a chance you have alone time when the nurse leaves and then the real doctor comes in that your moment to throw away all evidence in the trash.

        Hopefully in the future weed is completely federal legal and taken out the 5 panel test cus is some bullshit to lose a job or career over smoking some innocent relaxing weed, weed doesn’t make me a hazard at any job even when am high.
        well not to dam high of course lol for all other drugs no excuses them shits are dangerous and fuck up your mind and body.

        Hope this helps cus drug test suck i been there lol
        remember this is only for
        pre-placement urine drug test Only.
        For saliva or blood or hair or military or federal or probation where they watch you pee you are fucked Good luck!

  • Gary says:

    And I forgot to mention that where I go to get drug tested doesn’t send the cup to a lab or testing facility. The cups they use tells you on the spot in a few minutes. With that being said would a lab or testing facility do more tests on you’re urine?

    • Mary Jane says:

      Most labs are going to use the same strips that you would get in a home test, which is why I recommend picking one up to test yourself. However, it is possible that the lab could order a GC-MS test which is outlined above. Best of luck. Let us know how it turns out.

  • Nick says:

    Mary Jane,

    First and foremost, the website you run is great. I really appreciate the information you are giving and how you respond to everyone’s questions and concerns. That being said, I have a 5 panel urine drug test coming up in 3 weeks (give or take a day or 2). I am going to try and push it out another week so I am closer to 4 weeks. I would categorize myself as a daily user (1 – 2 bowls a night before bed, occasional blunt on the weekend). I am VERY active… weight lifting + cardio 5 days a week, 3 – 4 mile jog 2 days a week (Total of 7 active days a week). My diet is VERY clean… nothing but lean meat, vegetables, fruits, throughout the week. Also, I drink nothing but water and coffee, with 1 – 2 alcoholic beverages on the weekend. My body stats are 5 foot 8, 165 pounds, 9% body fat (Not trying to sound dooshy by posting that, but I just want you to have as much info as possible).

    My Question: Do you think I will pass my drug test in 3 weeks if I continue my current regimen? If not, what do you recommend? Obviously, I am not smoking right now, and will be clean exactly 3 weeks when the drug test comes up.

    Thank you!

    • Nick says:

      Also, I have been working out/ dieting like this for a couple of years now, so I think my metabolism is running on all cylinders.

    • Mary Jane says:

      Overall your regimen sounds pretty good. Make sure to switch to fatty foods and stop exercising 3 days before the test. Also, definitely pick up a home test kit at your local pharmacy (or online since you have a little bit of time.) If it is possible to push it back a week then added more time is always beneficial. Best of luck. Let us know how it all turns out.

      • Nick says:

        I got my test pushed back 1 week, which will give me exactly 4 weeks from my last toke session. I went ahead and took 2 home tests as well and will take 2 more before the test. I took the 1st test after 10 days of being clean and passed it. The second test I took earlier this morning and passed it, and it was my second pee of the day with only 1 bottle of water in my system. The test I am using states that it uses the 50 ng/ml cutoff, which is the same as the test I will be taking in a couple of weeks. Do you think I will be in the clear once the official test is conducted in a couple of weeks? As stated in my earlier post, I drink nothing but water, workout + cardio 6 – 7 days a week, and eat VERY healthy. Also, how accurate is the take home test when compared the the test the clinics use?


  • David says:

    Have not smoked anything for 4 weeks (and don’t plan to smoke anymore) how do I get my system clean. Or help it get clean enough to get a job.

  • Lrl31 says:

    I just used xtream and my test was not supervised. It was sent to a lab 2 days ago. I have never used synthetic urine before and can’t find many reviews on xtream. Just looking for reassurance.

    • Mary Jane says:

      I’ve personally used xtream and it all came out just fine. Of course, there are never any guarantees in life, but I don’t think you should have any problem as long as your temperature was correct.

  • concerned smoker says:

    i have a piss test to take by 9:00 am on sun mar 27. i had stopped smoking monday march 21 and that night i took a citro (spell check) but little jello box with a gatorade. then took another one tuesday mid day. around 3 i took a at home drug test and didn’t pass.

    Sadly i smoked wednesday night only 1 blunt.

    Today (Thursdsay) I have not smoked anything and took 2 niacin pills (500mg) and am drink water. i was going to go and buy another “citro” and continue drinking large amounts of water and take 2 more pills later this evening and repeat the same thing tomorrow.

    Question: should i even go through all that to see if possible i pass the at home drug test or just go and buy a replacement.

    My drug test is for my job
    I am 190 5’8 dont really have any body fat at all
    But could really use some help.
    Although part of me says just go get hte replacement and go take the test today

    • Mary Jane says:

      It is possible to pass via dilution, however, given how recently you smoked you’re probably better off using the replacement method. I normally do both. I buy synthetic, but I also try to get my natural urine as clean as possible. The replacement is first choice, but it gives me a backup in case I can’t use the synthetic for some reason.

  • kk says:

    I have been on probation for about 8 months. I haven’t smoked or drank any liquor during that time frame. However, on march 4th i had a meeting with my probation officer about an early release from probation. With that said, during the meeting he said he had taken me off drug test because i have finished everything i was suppose to (community service, therapy, etc). He also said that he will send my early release papers to the courts to have them signed by my judge. Anyway, I made a bad choice after my meeting and went and bought some HIGH level thc wax because i didn’t think i would be tested anymore. I smoked everyday for about 20 days. On march 22, i got a call from my probation officer and he asked me to come in to take one last drug test on April 4th before he sends my paperwork to the judge to sign. I will be around 12-13 days clean on april 4th. I am taking niacin, all natural cranberry juice with added fiber, a 7 day dextox pill from walgreens, green tea triple fat buring pills. Not only that but i also started the process with a 2 day fast. I will be buying home testing strips. However, i will mostly likely have to dilute my sample i think. Nevertheless, i will let you know how the test goes.

    It frustrates me that my probation officer used a immoral tactic of lying to try to get me to slip up. Things like this make me anxious for the second coming of the savior. With that said, what goes around will surely come back around to my probation officer.

    I am trying not to stress but rather, only believe. I will pass this test but will post an update once its all said and done.

    thanks you for this article.

    • Mary Jane says:

      That’s such bullshit that he told you were done with testing, and is now giving you a test. You did everything right and got screwed over for it. With that said, it looks like you’re doing a good job with your plan. Please do let us know how it turns out. Thanks for sharing and best of luck always!

  • Bman says:

    Thanks for this thread! Here’s my current situation:

    I may or may not have a preempoyment drug test so I’m currently detoxing. My second interview is April 4 so I may have to take the test sometime after that if offered the position. Not sure exactly when but I’d wager I will have atleast 2 weeks of no MJ use under my belt.

    I would consider myself a heavy user (between 1 and 4 blunts a day for months prior of mid grade bud). I’m currently 5 days clean (last smoked March 24).

    I’m currently working out daily, both cardio and weights. Trying to drop a few lbs. (I’m currently down 5lbs and weigh 231 lbs) Taking soluble fiber daily, a multivitamin that has 50 mg niacin with lots of other stuff, as well as 400mg acetyl L-carnitine. Which claims to aid in detox/ and boost motabolism.

    3 days prior to any test I will stop working out and eat a higher level of fats to stop the release of thc metabolites into my urine. Day of any test I plan to dilute with water and take a large dose of fiber and b vitamins to color my urine yellow.

    I will test myself at home before any test to make sure, but I’d like to avoid substitution if possible. I just don’t trust synthetic urine or my ability to give a sample at proper temp.

    So do I stand a fighting chance? Should I also try a detox drink before any test? Any advice is much appreciated and I thank you for your work and time on this, most stressful subject lol

    • Mary Jane says:

      It sounds like you’re doing most of what you should be doing. You could buy a detox drink, but the dilution method with suppliments works well too. Since it’s for a job you may want to consider also getting some synthetic urine. When possible, the replace method is best, but you’ll also have your own urine as a backup in case you can use it. Best of luck. Let us know how it turns out.

  • bman says:

    Thanks for your quick response.

    Is synthetic urine really worth it? Do you recommend a specific brand?

    I’m just concerned how I would transport it and make sure its at the proper temp. What kind of container would work best? Ive heard a condom, but I’m already sweating thinking of it rupturing and looking like I pissed my pants in the testing facility lobby.

    Unrelated but even just my 5 days clean so far with working out has really improved how I feel. When I worked out while using daily I pretty much felt like a sloth and labored through what ever it is I was doing. It may be strictly mental, but I feel much more explosive. So there is a silver lining for those that are doing a detox like me. I love weed more than most so if I can do it there is hope for all of us lol

    Thanks again for your time!

    • Mary Jane says:

      I’ve used sysnthetic on 3 different occasions and it’s worked out for me every time. Of course, I can’t ever guarantee anything 100%. Don’t use a condom. Whatever synthetic you use should come with a bottle. I use medical tape to attach it to my inner thigh. The two brands I’ve used are x-stream, and quickfix.

      Glad to hear you’re feeling good. A little t-break can do any smoker a bit of good.

  • Cee says:

    I haven’t smoked in about 10 days, I’m an occasional smoker, I’m around 100lbs and 5ft. I jog every other day and having been drinking around like 3 liters of water a day. I have a test tomorrow around noon; what are my chances of passing? Have you passed just doing the dilution method alone? I don’t really have the time to get a replacement. Most smoke shops close by the time I leave work today, but I could check.

    • Mary Jane says:

      It is possible to pass using just dilution. Make sure you’re taking the suppliements outlined in the article. Also, I HIGHLY recommend picking up a home test kit at your local pharmacy. Best of luck.

  • Ryan says:

    So I took a drug test the other day and it was one that had to sent to the lab and it was a 5 panel. It had been 13 days since I last smoked and I was smoking pretty regularly on a daily basis but only for a month before that I was clean for a month. In the 13 days I was working and sweating a lot and also taking my vitamins everyday and diet pills. On the day of the test I drank HerbalClean 36 something like that and drank a lot of water. Just seeing your guys opinion if you think I may be in the clear. I also used the midstream technique. It’s been 2 days and still no word from the lab. What do you think?

    • Mary Jane says:

      Sometimes these labs can take a while. Also, depending on why you took the test your likely not to personally receive the results. If it’s for a job then they are likely going to send the results directly to your employer. I think you have a good shot, but who knows. The important thing is not to let yourself worry – nothing good can come from worry.

      • Ryan says:

        Well I took the test Saturday so not including Saturday or Sunday today would be the fourth day. The lab is medtox. Anyone dealt with them? Know how long it takes?

  • fr says:

    I only smoked 4 times out the month the last time I smoked was on the 19th been taking niacin everyday and multivitamin everyday drink water and gatorade go on walks and pushups will i pass on my test on the 4th I will have exactly 15 days with no weed I’m an occasional smoker I’ve never smoked day after day

    • Mary Jane says:

      Have you tried taking a home test? It’s the best way to know if you’re clean or not. You can pick them up at pharmacies in most countries. Best of luck.

  • Juicy says:

    Can you drink Palo Azul while pregnant to clean your system?

  • Ryan says:

    Has anyone dealt with medtox labs? Do you know how long it takes to get results from a 5 panel DOT drug test?

    • Mary Jane says:

      I haven’t but hopefully someone else will chime in. If not, please come by and let us know when you get the test back. Thanks, and best of luck.

  • Vali says:

    Has anyone taken the utest at home tests (20ng) and passed and then passed at the lab? I’ve taken two of those and a first complete from the pharmacy and all passed yesterday and today. I smoked on the 18th and 19th of this month and before that it had been a year. I have my test tomorrow. Should I still focus on dilution ? I’m just nervous Because of the home test accuracy. Thanks!

    • Mary Jane says:

      I have passed a home test then passed a lab test. Most lab tests use the same technology as the strips at the store. Of course nothing is ever guaranteed. It’s not a bad idea to use dilution, but make sure not to overdo it. You need color, but you also need the proper creatine level. Best of luck.

  • Grandmaesterfunk says:

    I stopped smoking a little over 3 weeks ago, drinking plenty of water and i had passed my at home drug screen with a nice clear dark line. I was a moderate smoker, 2-4 times a week. What are my chances of being in the clear for my pre employment test tomorrow?

  • Makaveli says:

    I have drug test on the 14th of this month. Im not super heavy smoker butsmoke like everyday, share 2 blunts with like 2 of my friends. I haven’t smoked in like 2 days and I plan on goin to sauna this week and taking fat burners with cranberry juice and gallon of water everyday. I’m 5’8 about 135 lbs. I also plan on buying cheap home drug tests too check my progress end of week. I also know when taking urine test to use your middle iTunes stream since has less toxins. I know everybody is different but am I likely to pass the test?

  • Anonymous says:

    Palo azul does work! You must drink it the day of and you must drink a whole gallon! I typically start drinking it a couple of hours before the test. And make sure you pee a few times after drinking and before your test. If your pee is clear you are clean! It is temporary. I have used this method for probation and for doctors visits. It really does work, it’s all about boiling it correctly and timing it right.

  • Pondo Sinatra says:

    Mary Jane,

    Thank you for creating this blog and taking the time to respond to posts. It has been most helpful. I am a daily smoker, 5’11” 220 lbs. I have abstained for exactly 1 week and during that time have been eating healthy, mostly salads. I drank lots of water during the day at work, came home and tested positive using test strips from Amazon. Urine was clear. I then drank a half gallon of Palo Azul tea, waited a couple hours and tested again and had a faint line showing negative. Urine was still clear. This gave me hope. I may have a drug screen coming up in about a week so I will be testing myself again several times to be sure but so far, it looks like this stuff may be legit. I will follow up after a few more tests.

    • Mary Jane says:

      Even if it’s a faint line then it counts. One thing you want to watch is how clear it is. If you pee clear during a test then the technician may mark it as untestable and you’ll have to retake the test. Looking forward to your follow up. Best of luck!

  • bman says:

    Hey again, I wanted to update you on my situation. I have not had to take a DT yet but my recruiter informed me one is coming as it looks like I may get the position. I was a fairly heavy user, 2 or 3 blunts a day, but after 12 days of no ganj, working out, hydrating, drinking a detox tea twice a day, and taking a multivitamin I am currently passing my at home drug tests! (I’ve also dropped 7 lbs from 235 to 228). I did purchase quick fix synthetic as an insurance policy but now I’m thinking I’ll just give them the real thing. At the point of any test I will have atleast 15+ days of abstinence. Does that sound kosher to you?

    • Mary Jane says:

      Congrats on the potential new position. You deserve it! Overall, it sounds like you should be good to go. Make sure you take a practice test right before you leave for the test, and make sure the color looks good- not clear. Best of luck, and please keep us updated.

  • Pondo Sinatra says:

    I’m not worried about it being clear. I’m taking B complex vitamins for that but but I am concerned about it looking bright yellow. I’ve heard of taking milk thistle to make it look more natural along with the B vitamins. Anything you or others can recommend to give it a more natural look?

  • Gvegas252 says:

    Hey MJ, I’m 5’10 225…I have 30 days to get clean I smoke on average 8th to a quarter a week…4 days clean so far lots for cardio and sauna and water..I have a Football/Military background so far I have lost about 7-10 pounds since I stopped 4-5 days ago…no sweets no fast food mainly salad and tuna..and I don’t eat ANYTHING after 7:00 pm…will I be good to go day 30!? Lol oh I have smoked the past few months but not daily maybe 3 to 4 days out of the week…

    • Mary Jane says:

      Everyone is different, however, most users are clean after 30 days. Given the fact you don’t smoke daily and you work out I would guess you would be fine. Remember that is just a guess – grab some home test kits at your local pharmacy. Best of luck.

  • Nettles says:

    I have used Palo azul tea and it worked. I take weekly drug tests for my job. I passed my first test in just 3-4 days of not smoking. I was in a car accident and was smoking daily while I was out of work. I cut down to 1-3 puffs a day for 2 weeks then the last few days only 1 puff. I ordered the tea followed the directions. The 2 days before the test I drank a gallon a day and nothing else. The day of the test I took b12 and drank 3liters of water to the point I was pissing every 20-30 min. I had smoked about 3 days before the test and I passed. Since then I have smoked 1-2 puffs here and there (knowing I had 3 days till my next test) and passed 7 times now. Each time I drank 1 brew of Palo azul the day b4, each time and drank lots of water with b12 the day if the test. It’s relatively cheap and works if you do it properly. Good luck.

  • LIsa says:

    Whenever I have to quit for a job I test myself quite often with a dollar store drug test for marijuana. Not sure how accurate those are yet because after plenty of torture I’ve been mouth swab tested twice. Not so lucky this time. So I thought I would add something that I find interesting. I get a much darker negative line when I flush with water first, drink gatorade and then eat microwave popcorn. I stumbled on it as a fluke one day when the negative line was significantly darker. I attributed it to the popcorn and tried it again. Sure enough it seems to mess with the results. Give it a try and let me know what you find out. P.S. Act 2 or 3 buttered popcorn.

  • Warner says:

    Hey MJ, I just got a job offer which will eventually require a drug test, most likely within 2 weeks since that’s when I will start. I’m a 5’6 135 pounds male fairly skinny and I smoke very rarely, maybe once every 3 or so months. I took a few hits (maybe 5- probably equivalent to a gram, wasn’t super potent) from one of those cigarette looking vaporizers 12 days ago. I’m obviously going to try to delay the drug test as much as possible but worst case scenario would be sometime next week, bringing the total days since smoking to 15-20. I’m planning on getting some home drug test kits but should I be okay?

    • Mary Jane says:

      You should also increase your exercise and eat lean meals up until 3 days before the test. Everyone is different, but you should be okay. Consider purchasing some synthetic urine as a backup plan. Best of luck.

  • Makaveli says:

    Hey, Just wanted to let you know my drug test is tomorrow Thursday morning and I just finished testing myself with a home drug test. The results came out negative with two lines! I feel very relieved! I used a $1 drug test should I trust the results?

  • Maybe screwed? says:

    I have a drug test coming up a week from today on April 21st. I stopped smoking on April 2nd. Since January i’ve smoked typically every other day but only a little bit, a total of about 5 grams in 4 months. I am 5’9″ and 240 lbs. I lift weights 3 times a week but don’t do much cardio. I am on the chubbier side. I have about a week to prepare for this test, what should I do to make sure i pass? I’ve ordered drug tests and will be checking myself soon. How likely is it that it’ll be out of my system before the test? It already feels a little late but should I start doing cardio/sauna now or is it too late?

    • Mary Jane says:

      Start doing cardio and eating very lean. When the test is 3 days away stop working out and eat a bunch of fatty food like cheeseburgers. Start practicing the dilution method outlined above. You want it to test negative, but you also need to have proper color. Depending on the circumstances you may be able to use the replace method as well. Best of luck.

      • Am I good? says:

        I purchased test strips on Amazon and I tested myself on Sunday and I tested negative. Today, I tested myself again, just to see if that was a fluke and it was negative again, however, the line was very faint. Should I be worried still, or should I be good to go if my drug test is at the end of this week?

    • Lynda says:

      I just came across this article and I have found very valuable information. I’d like to add some of my experiences if of someone would find them helpful. I’m 32 Now and haven’t taken a drug test in years, but have been an active smoker since the age of 14. I have used the dilution and niacin method 3 times and have passed all 3 times. Since this was years ago……i was in my early to mid 20s , height 5’3, weight between 120-135. Since testing is typically in short notice, I would stop smoking a few days before and chug 2-3 gallons of water the day before and the morning of. I would also take niacin. I dont remember how much, but enough to turn beat red and itchy for up to 45 minutes. I definitely recommend this method.

  • ace says:

    hey, so theres a good chance i have a piss test for court on the 4.20.16. thinking i was gonna go to court sometime in june, i thought i had a couple more weeks to toke up before just naturally cleansing. with no surprise court was scheduled on the 20th because thats my luck. my last day smoking was 3.31.16. so today is 14 days smoke free. i am currently using the niacin, water method. so if i take a test the 20th ill let you all know the results in my experience. but i also want to recommend eating lots of tuna fish. because in the beginning of feburaury i had a surprise piss test and smoked several days straight not knowing. but i was also on a tuna fish kick for some reason, so a week later i got a call saying i passed the test totally expecting to fail. i know the tuna sounds weird but im gonna eat alot of that a few days before court lol

  • Peter says:


    I took like 3-4 hits of a joint (marijuana and tobacco). I have never done drugs before. I have a drugtest (urine) that will be 5 weeks after the intake. Will I pass? The screening is at 25ng. I do have a little extra fat on my body and I don’t workout really much.

    Thank you!

    • Mary Jane says:

      5 weeks should be enough time. Grab some test strips to be sure. Also, go through the article above and see which methods work for you. Best of luck.

  • Greenman says:

    First of all, love your work MJ – very informative and your responses to comments are really reassuring. I’d normally be too paranoid to post a comment but I feel I should, to give others as much information as possible to assist their own situation.

    My story: I’ve been a medium to heavy smoker for 10+ years, now I smoke an average of 4g/week potent ganja, sometimes less, rarely more. I started working at sea about 8 years ago – we suffer an EMIT (strip panel) type test every 2 years along with a medical, but are also subject to random testing at any point between joining and leaving a vessel. This had me worried at first and I considered stopping altogether but after thinking about it I thought “Fuck those guys, NOBODY is telling me what I can and can’t put in my body”. So I made a conscious decision to continue to smoke because I enjoy it and take steps to mitigate against the dreaded piss test.

    I’m 185cm, 85kg and low body fat. I keep reasonably active and cycle about 12km every other day, as well as semi regular bodyweight exercises. I’ve passed every single piss test no problem using the dilution method supplemented with Zydot Euro Blend. This particular drink has worked for me – I’ve used it on the day of the (morning) test after smoking 2-3 joints the previous night and passed with no prior dilution – although after reading your blog it would seem that all of the required vitamins can be bought off the shelf for way cheaper and do the same job! It sounds like the general consensus from the comments is that dilution works; but I also like your idea of having a synthetic on hand for emergencies.

    I usually have 3 – 7 days notice before going to work so my method nowadays is first of all to stop smoking immediately and begin diluting. Pack a Zydot in my bag just in case. Extremely rare that a test will be given on day 1 of a job so I continue my routine and fingers crossed that I won’t have to pee in a cup during my trip – thankfully I’ve never had to at random, but I like to err on the side of caution and assume I will be. Especially after hearing a crew were tested recently and the tech said they were all being sealed up and going straight to the lab for GC/MS – no grounds for it, just trying to catch people out I guess.

    Bottom line from me is: Drug testing employees is bullshit, even more so in the case of weed which in my opinion is a relatively benign drug but stays in your system for a (pot-entially) long ass time. Any information that can help people to pass and feel confident in their piss is a good thing and I applaud your stellar efforts at helping to educate and reassure people – keep up the good work and those of you stressing out, follow the advice given in the blog, take whichever measures you can to protect yourself and please try not to worry!

    Any questions, feel free to ask and I’ll respond as soon as I can!

  • Dmart says:

    Hello, I have a piss test this Friday (today is Wednesday) I haven’t smoked since Sunday night. I’m 6ft 170lbs, active lifestyle and low body fat. I’ve been tested in the past (5 times ) and have used the “detox” drinks every time and passed. Followed the instructions on the bottle and everything worked out. I’ve been drinking lots of water and 3L of cran juice, along with healthy greens and supplements daily. Always nervous to piss but I’ve passed before with as little notice as 5 days. This time il be using “high voltage detox”, and plan to get the strips. I will message back and let everyone know how it goes! Great blog thanks eh!

  • Matt says:

    posting some results. and expected test soon. I recently left a job, 4/13. im 6ft 200lbs, some extra body fat. up untill 4/13 i would say im a fairly heavy smoker. Close to a gram of Loud a day on average.

    After leaving that job i have been cutting WAY back. Hitting the bowl once or twice at most, usually. i had a slip up one or two days since, smoking more, but mainly its been Very light, up untill 4/20, i hit the usual small amount that morning. and have stopped totally now.

    On 4/20 i went in for 2 interviews, both required drug tests seemed to be EMIT panels. I passed both without any issues with the Substitution Method, will post my method, which does not particularly work if you are being observed, ive rarely ever been watched though only for walmart..

    Materials- Clean urine,Cargo pants, Condom, Hand or toe warmers, and preferably small scissors or nail clippers and some silent thermometer.

    I brought a beeping digital thermometor to check pee temp in the car outside. was a little over 100 outside in my car. with a silent one you can check exact temps inside the bathroom. I press directly in through the reservoir tip to the middle of the condom. as long as you dont tie your condom off with loads of pressure theres no danger of puncture/bursting

    Wear your cargo pants, they will not make you empty your cargo pockets. Head to your local walmart and score you a pack of Trojans and a pack of handwarmers.

    Your Clean Pee goes into the condom which you will tie off to close up.
    Open up your handwarmer pack to activate your hand warmer.
    Once its hot, it goes into your cargo pocket. followed by your clean pee condom, Which i usually soak in hot water to bring up to around 100 base temp, then dry thoroughly.

    Your scissors/nail clippers are for opening your condom’s tip, clip the reservoir tip for easy dumping. You can stash it in your other cargo pocket, or your boot. Or u can easily attach the clippers onto the top of your underwear.

    I start one of the jobs monday, and i believe i will have one more piss test. i will be using this method once again, as it hasnt let me down so far. I also do not know if it will be an observed test, so i am prepping for that as well. 2 days into niacin regiment 1k mg first day 1500 so far today. drinking loads of fluids, moving around more than usual. I may do a tea cleanse to boot, if i need to. Plan to test myself Sunday night with just the niacin/flush and dilution. also taking multivitamin to build up color and other dilution clues they key onto.

    as for the niacin flushing, it doesnt bother me nearly as bad as the itching i get. the flushing stops after about 30-45 min, the itching doesnt really stop at all. anyone know how to counter the itch? benadryl maybe, think i will try it.. and i will update when applicable

  • Ryan says:

    I was wondering if I could get some advice or feedback on my upcoming drug test. Basically, I have an upcoming drug test in 10 days with a cutoff threshold of 150 ng/ml *Olympic style testing. I’m 25 years old, weigh 145 pounds, have a fast metabolism. I smoke twice a day *half a G of KB per sitting* During the day I would wake n bake, head to school, work out and smoke before bed. This was my everyday routine. I am planning on not smoking for the next 10 days and continue my workout routine. Unfortunately, since I will be at a tournament I can not stop working out previous to my drug test. I am planning on using the diluting method. What’s the probability of me passing this test? I am a professional athlete that works out as much as I smoke. Very low body fat and crazy fast metabolism. Thank You.

    • Ryan says:

      Also, substitution is not an option!

      Unfortunately, there is no way for me to say if you will pass or not – everybody is different. Go to your local pharmacy and pick up some test kits. Do everything the same way you would for the day of the test and check the results. Best of luck!

  • Bman says:

    Had the big UA pre-employment test yesterday after 34 days of no use. Passed a home test before and after so I believe I’m good… Was told 2 days for results, do you think its safe to celebrate this weekend?

  • Stash says:

    So, I just typed out this long ass comment and right before I hit send and my phone died. so I’m going to do it again through voice text but it does not capitalize so Grammar Nazis please leave me alone. here’s the deal I’m 50 years old about 178 pounds and 5 8. I work as a caterer so I’m very active and I’m always sweating my ass off at work. I’ve been on probation for almost 11 months and I’ll be off in June. I quit smoking before I was put on probation so I had no problems passing the first drug test she administered in the third month of probation. She had never asked before but she said that she always gets the urinalysis from anybody who request a travel permit. Also I should add in the beginning she had me answer all these questions about drug use and alcohol use to determine if I needed to take a drug and alcohol class even though my offense was not drug-related. I lied my ass off and made it sound as if I hated drugs of any kind even marijuana because my mother was a heavy user and my son was actually in prison for marijuana use. I guess I said the right things they didn’t have to take that test. I continue to stay clean until she allowed me to do some mail in appointments for three months. so I decided to celebrate the holidays by blazing up regularly for about one month. That gave me 2 months to get my system clean. the next time I went to probation I needed a travel permit again. She didn’t ask me to test that I asked her if she needed one because I really needed to pee(plus I knew I would pass because it had been 2 months) and she said yeah sure go ahead. well the line for THC barely showed up and it took longer then it did the first time. she said she would consider it a pass but asked if I smoke cigarettes. I told her yes I really want to quit though. Then she asked me if I ever smoke electronic cigarettes. I told her I don’t smoke them regularly but sometimes when I’m at work I’ll take a hit or two off of some of my friends because we are not allowed to take smoke breaks. She told me to be careful of that because some people smoke marijuana out of them and there could be residue left behind that would cause me to fail. she then gave me another 3 months but mail-in appointments. I had only smoked about two weeks this time so I would have, 10 weeks to clean up. but now I have to go in on Monday because she needs to refer me 2 my community service since I still have hours to complete. I smoked last Sunday which gives me about 7 to 8 day period of time since I smoked last. I found out about it this morning so I bought some B12 and begin taking that. I also bought a detox called protox. I follow the instructions exactly just to see if it worked. I drink 3 glasses of water over 1 hour period of time and then consumed the protox. I waited 15 minutes and refilled the protox bottle with water and drink that. About 30 minutes later Pee Fest 2016 began. it hit me like a ton of bricks and I suddenly ran to the bathroom to pee. I didn’t think I was going to make it. after that I went to the bathroom every 10 to 20 minutes. On the 3rd round I tested my urine and it was a fail. I tested again the next time I had to go it was a fail. on the next time after that there was a very faint line. (barely a pass) then I tested the following time and there was no line. So I barely was able to pass once. I don’t think the dilution method would work for me because I have to pee so frequently. I did buy a stronger version of the protox to use that day. the amount of protox is double what I drink before. I was barely able to consume the smaller amount without feeling like I was going to vomit. so I don’t know if I would be able to keep the larger bottle down. I would like to add that this time around I have been eating pretty healthy for the last 3 weeks. very high fiber and very low fat. I probably weigh less but I don’t have a scale so I can’t say by how much. I just read that I should consume a high-fat diet for the 3 days beforehand so I ordered a big pizza and just ate 3 pieces. I have a friend that’ swears Palo Azul. also there is no way for me to avoid exercise and sweating because I have to cater Friday Saturday and Sunday. That is I’m going to mean 12 to 15 hours a day each day I’m sweating my ass off.again the test is on Monday if she asked me to take it. She probably won’t but still I want to be safe. Does anyone have any suggestions ? also I would like to say all the potheads need to get out and vote to get this legalized. This is so annoying. I am about to leave the state and move where it is legal. Ugh. Sorry for the long post.

  • Samantha says:

    So I smoked this past Saturday for the first time in over a year. I just got a call about a job and if I get it I’m going to have a test. I only took a few hits off a bowl over the course of about 5 or 6 hours, and the weed was pretty strong. I feel really dumb that I even smoked and more so that I’m having to go google this and ask some random people this question. I just wanted to have some fun and celebrate graduating college. My friend gave me a bottle of synthetic urine but I’m scared to death to try and use it. I go meet with the manager Thursday so I probably won’t have to take a test until next week or so if I’m hired. I’ll go get some of those tests, but what do you guys think? You think I’ll be okay?

    • Mary Jane says:

      It’s hard to say, but it is possible since you only smoked a little. In addition to what you mentioned, you could start practicing the dilution method. Synthetic is super scary at first. Luckily, it’s for a job so it’s unlikely you’ll be watched. Once you go in the bathroom, you have the whole place to yourself to make the switch. Best of luck. Let us know how it works out in the end. Cheers!

  • abel says:

    the best way to pass is to use this stuff called CertoClear, get it anywhere online. It worked for me 2x before

  • Luke says:

    I stopped smoking Easter weekend in prep for maby getting a job that would require a test, I hadn’t really done much in terms of trying to get it out of my system, just regular exercise and I drink between 4-8 litre’s of water a day as I currently work in the sun for 8 hours a day. I have now found out I’ll be tested in 2 weeks time so I got a home drug kit and tested myself and I’m still testing positive, ( barely but still positive) what would you recommend to help speed it up ? And also I’m shocked it staying in my system this long as I am a slim build 65kg(143 pounds) 5 10

    • Mary Jane says:

      Keep drinking water, working out, and eating lean meals. Keep testing yourself. If you’re still positive a few days before the test I would practice the dilution method and consider the replacement method. Best of luck!

  • TDub says:

    I have successfully flush my system using water. I self tested my urine and it’s clean. Now my question is this…… if my urine is now clean my saliva also?

  • Greg says:

    I am a very infrequent smoker. Before last night I had not touched weed in over a year and only smoked maybe 5 times in my life. Had only 2 hits from a batty or whatever last night but it messed me up pretty good. Urine test is in 3 days. Like my odds of passing or not so much?

  • Shniff says:

    Great info on here, thanks so much. What container do you recommend with the substitution method? I’m thinking it shouldn’t be bulky to tape to inner thigh?

  • Mason says:

    I have used the niacin and water method for 8 years I have successfully passed 6 drug tests with it. I buy Nature’s Bounty 500mg Niacin FLUSH FREE (that part is very important so you don’t turn into a lobster). Each time I stop smoking the day before the test and start with 4 niacin and drink roughly 2 gallons of water. The day of the test I start with 4 niacin and drink a gallon of water and pee as much as possible before the test. I take and additional 2 niacin about an hour before the test. I realize that niacin is dangerous however the most adverse effect I’ve ever had is a headache. I am a heavy smoker and this method has not failed me yet.

  • Bobby says:

    Does visine work?

  • Dean says:

    I stopped smoking Thursday which was 4 days ago after finding out I’ll be drug tested at some point soon. I get high easy so smoke maybe a joint a day for the past 3 years. I’m 5’4ft and weigh 60kg so a small woman. I’ve 7 days to get actual clean for a urine test, already stopped for 4 but done no method to clean this out! Your article was so helpful. I plan on exercising like mad and niacin. Is niacin a dilute or will it actually clean me out? Any help is so appreciated! Going to cardio and water/ naicin for the time being with a good diet. Hard to judge how long it will be in me since I smoke little but for a long period.

    • Mary Jane says:

      Glad the article helped. Niacin is a chemical flush – it doesn’t dilute. I always recommend picking up some home test strips if you can. Best of luck!

  • K12 says:

    I smoked a gram of dro with a friend two weeks ago, I may have consumed half or less of that gram but it was good good. I drink lots of water cranberry juice lemon unsweet tea and my job is construction so I sweat alot but I weigh 220 and about 5″10. Will I pass in 15 days from that smoke session? Im very infrequent user as well been years since last toke??? Need answer fast thank you so much

    • Mary Jane says:

      Unfortunately, there is not way for me to tell you if you’ll be clean. Everyone is different. The best I can tell you is to pick up some home test kits to test yourself before going in. Best of luck!

  • Hawk Fan says:

    I bought Quick fix 6.1 from their web site and you mention many times to verify the expectation date on the package. I can’t seem to find a expiration date on the package. Should I call and verify the expectation date with the batch number?

    • Mary Jane says:

      Yes, I would send them a quick email or call about the batch number. I feel like they used to print the expiration date right on the box, but I could be mixing it up with another brand. It would be great if you could let use know the batch number and expiration when you hear back from them. Cheers!

  • Home says:

    So, here I am; hoping to pass an ecup test for a really important job. I should have stopped smoking sooner but it’s only been 3 days. In 3 more days I’ll be taking the test. This isn’t my first rodeo but I still can’t shake the nervousness or fright of failing out. About 10 years ago I passed my first and only pre employment pee test using the niacine meathod on short notice. Since the. Ive been a constant smoker and hope that i xan pull it off again. This is was I did: stop smoking immediately, everyday take several niacin pills (I was comfortable taking around 1500-2000 mgs a day, I don’t advise this for everyone because it isn’t healthy, just take what is comfortable and be sure it’s more than the recommended dosage for results), 1 gal of pure cranberry juice, 2 gallons of water. NO FATTY FOODS. I repeat NO FATTY FOODS. Otherwise you may fail. No strenuous exercising the day of or the day before the test. The day of the test, take 2 niacin as soon as you wake up and down a diuretic drink like coffee or green tea. This is important: do not eat before the test. Drink a large amout of water and take 2 to 3 B12 viatimins. Be sure to pee at least 4 to 5 times before taking the test.for safe measure take 2 more niacin know the way out the door to the lab. When you pee use the mid stream. This is the meathod I am currently using because I know it worked before. There are never garuntees but with a little prayer and perseverance it should work again.

  • harley says:


    I used to smoke 2 to 3 puffs daily for 4 months, then they test me as a pre employment without notice, I used the dilute method and it was inconclusive (they did not tell me). Then I did not smoke for 19 days and then smoke 1 puff every day for 5 days, then I stop for 6 days, I took a CVS drug test with my concentrated urine and it turned negative, but the line was really faint. Then I continued 4 days more without smoking but then I smoked 3 separated days. I came back and they re test me, I only drank a lot of water but the specimen showed low creatinine so they want to test me again. I re took a CVS drug test a week ago and was negative again with a slight line. Its been 8 days without smoking and I have to re test this wednesday but they told me not to take water before the test…I am pretty concerned, they send it to a lab and comes back in 2 days but I dont know if they use yhe 50 ng cut off.

  • ADLR says:

    ok I have a random drug test that I am suppose to take tomorrow so if you could respond quick that would be awesome. I haven’t smoked in almost 2 years but I smoked this last weekend on Saturday I took a couple hits but since sunday I have been drinking lots of water and apple cider vinegar and drinking coffee. will I be able to pass my UA test tomorrow ? Its been like 3 days since I smoked and my pee is clear.

  • ADLR says:

    Also I took this test that is called and IDenta Marijuana/Hashish Identification test, I peed on it and did everything the instructions said to do and no color came up with means there was not indication of marijuana but I’m not sure if this test works on urine or not.

    • Mary Jane says:

      No, it’s not the same thing at all. Go to your local pharmacy and pick up a test kit specifically for urine. Best of luck.

      • ADLR says:

        Even if I haven’t smoked in like two years and only hit like 2 to 3 times do you think I will fail still? that’s all I want to know. I’m really nervous. I know I shouldn’t have smoked and I slipped but I really need to pass this test.

  • Jason says:

    Dilution is really iffy in my experience. I just failed a drug test I had to take for work, however they didn’t fire me luckily. I’ve used it and passed before, but have also failed. This last time I actually hadn’t smoked in about 2 weeks and I really diluted my urine, I was peeing clear for 2 days. The only thing I was worried about was it coming back as too diluted but I got the phone call saying I tested positive for marijuana. I also failed one for a pre-employment screening about 10 years ago, that time I don’t know what went wrong. I had less clean time, only about a week, but the problem was that it took way too long for me to start peeing clear. I’d started hydrating the day before, and didn’t have to take a test until 4pm the next day. I woke up early and was hydrating all day but even though I peed probably 10 times that day I was still peeing yellow by the time I went in for the test. It wan’t until late that night that it started coming out clear. I haven’t tried any of the drinks since the 90’s, maybe they’ve gotten better since. One time it was so nasty that I threw it up and another time I used it as directed and still failed. I have a friend who swears by them even after he lost his job for coming up dirty after using one. As the old saying (that none of us like to hear) goes, abstinence is the only guaranteed way to pass. Funny story, one time I went abstinent for 2 months in order to get the job I currently have, and when I went in for the test it was just one of those dumb oral/saliva tests that you can pretty much pass just as long as you’re not high when you take it. At most 3-4 days is all you need. Sadly they stopped using those and went to urine tests.

  • Sleazyb says:

    Ive used quick fix 6.1 to get my current job. It went through lab corp. It worked. I was so happy i sent them a thank u card lol.neway i stopped puffing for a year. Im on vacation now so i smoked 1\8 of sour d. I got a bottle of quick fix waiting because i know it works. Ive never been randomed tho and its possible i could be. I suggest to practice so your not fumbling around in the stall. My question is can u mix a lil diluted urine with QFix to give it a little foam and odor. Qfix has no foam at all. Ive used it and passed but i would like to make it a bit more realistic . i love this forum great job MJ

    • Mary Jane says:

      I wouldn’t suggest mixing any real urine with the quick fix. I know what you mean about the foam, but I don’t think it’s a big deal like the color is. Best of luck, and thanks for checking out my blog 🙂

  • jayzon e says:

    i always passed on niacin as a truck driver/equipment operator. i simply take 1200-1500mg of regular niacin the day before and drink plenty of water pee several times and thats it.never take more than that or you will end up in hospital and take several years to recover like i did but i still use niacin for drug test cause i know it works.1200-1500mg the day before&plenty of water.

  • Sean says:

    Hey great site,

    I’m a nervous wreck because I have a test for the job of my dreams. I smoked about 1g every day for 4 years, I am 5,9 weigh 145 lbs pretty slim and would say a faster than average metabolism.
    I stopped on the 2nd of April until a week ago when I had one joint. My test is on the 15th of July so it would of been like 105 days since stopping apart from that 1joint. Will I be okay??

    Your help is greatly appreciated, it’s good to read an honest article and listen to good people, I swear some sites that say it takes longer than 2 and a half months are just representatives from drug test kit sites.

  • Tom says:

    I have 1 month and a half before my drug test found out today. I will stop as of tonight.
    Will being around smokers have an affect or should I just completely avoid being near people who are smoking. Really annoying though as all of my buddy’s smoke haha

  • lastsmoked-Juy 27 2016 says:

    This forum is so helpful makes me feel more confident in testing myself in another 10 days

  • Roch says:

    Thanks for the comprehensive article and responses back, MJ – I feel like that rarely happens anymore on most blog sites.

    Anyway, my deal: female, 5’4″, fluctuate between 155-160 lbs. I would call myself a moderate user; I don’t smoke that often (maybe 2-3 times a month), but I usually end up smoking at least 2, sometimes 3, bowls in a sitting.

    Last lit up on the 4th, and did 3 bowls. I’ve been job searching, had an interview today and basically cinched the job. It’s for a healthcare position and they specifically said they test for nicotine, but I’m erring on the side of caution and assuming it’s that and regularly tested drugs too. I’m also assuming that, if I get the call back, I’ll be tested within 2 weeks, if not next week.

    Right now I’ve been drinking water, Gatorade and pineapple juice, and upping my fruit and veggie intake. I rarely eat meat, and even then it’s seafood. I drink Monster like twice a week, no other soft/energy drinks. I exercise, but it’s not insane, balls-to-the-wall cardio; and I take a multivitamin every day that has both B12 and niacin. Current plan is to stick to that, while upping my fluid intake as much as safely possible and exercising like a motherfucker. Do I have a reasonable shot at passing or nah?

    • Mary Jane says:

      There’s always a shot. I always say the best way to know is to pick up some test strips at a pharmacy, or you have time to get em on amazon. Best of luck. Let us know how it turns out.

  • Ameeka says:

    So I’m 18 years old, i weigh 217 and i am 5’4. I’ve been smoking marijuana for the past year on and off. The past 2-3 months i’ve probably smoked every day sometimes more than one g a day. Im applying for a job as a receptionist at a clinic and i know they will drug test. I’m not sure how long i have to get clean right now it is just scheduled phone calls that i’ve had. They called me today and told me they would be getting back to me mid next week to update me on where we are. I usually work out once a day if not 3-4 times a week. I drink a lot of water and i don’t eat a lot i have a really bad eating schedule and sometimes only eat once a day. I’m guessing i have about 2 weeks minimum to get clean for the drug test. Are there any tips you guys can give me? I’m going to quit smoking because i know thats the best option since i have a bit of time but im not sure what to do other than workout and drink a lot of water. Please help me out any advice is appreciated.

  • A Pot Smoker says:

    I have to take a pre-employment test next week. Stopped smoking 9 days ago. I’ve been experimenting with dilution methods at home but cannot pass a 50ng cut off test. I’ve done A LOT of reading about all of this over the past two weeks and here is what I have found to work and be the least detectable method. Buy a bottle of zinc supplements at the store. Smuggle one pill into the test. Pee in the cup and dip that pill into the urine. I’ve done this three times and inserted a test strip into the sample pre zinc dip and post zinc dip (so the same sample is being tested both ways). The sample pre-zinc is testing positive. The sample post zinc is testing negative. I can’t say whether this will work for me for sure (haven’t tried it yet) but it’s the plan I am going with. Good luck!

  • Snafu u says:

    Smoked ever night for a while, most recently all O.pen. Got a last minute notice for a test. Been clean 10 days. Got a very faint second line on a home test today. Test will be sometime this week, going to go the Niacin route. Any good in adding Asprin to my intake prior to the test?

    • Mary Jane says:

      I’ve never heard of using asperin so I can’t really say for sure. The good news is a faint line is still a line meaning your test kit was negative. Best of luck!

  • Stevie says:

    Hey this is the best article I’ve found, I’m a bit nervous I should be fine just wanted your opinion. I have an average metabolism and am 23 yrs old, I weigh 150 lbs. smoked about a q a week I have been clean 1 month and 20 days, have a drug test in the next week sometime. Do you reckon I will pass. I would of bought a test but in Australia I cannot find them anywhere. Thanks for your help

    • Mary Jane says:

      That sucks that test kits hard to find in Australia. Perhaps you could find one online that can ship within a week. Aside from that, 1 month and 20 is typically more than enough time for your body to naturally detox. Of course, I can’t say for sure since everyone is different, but I have a good feeling about your case. Best of luck!

  • Kristine says:

    Hey, so I’m a 5’2 female weighting around 125 lbs. Really nervous because I have a urine test coming up in a week and half. I smoke 3 times since January 2016 and the last time I smoked was late May (about five puffs). I’ve also started working out for the past two weeks with pilates (but its not high intensity cardio). I will also be buying a home kit (arriving this Friday) and posting my result here but I wanted to hear some opinions. Really nervous!

    • Mary Jane says:

      The test kit is always the best way, but given the fact that it’s been about a month and half I have a good feeling. Go ahead and grab that kit from your local pharmacy just to help clear your nerves. Stress can really wreck a person so put yourself at ease. Best of luck 🙂

      • Kristine says:

        The urine test is a non-DOT standard 10 panel test. I’ve been testing myself every single morning and been testing negative so hopefully all will be good and I’ll pass! Thank you for being supportive. 🙂

  • Jon says:

    Hey there,
    I smoked about 2gs a day for 5-6 years. I haven’t smoked in 90 days what do you think my chances are of passing. 160lbs 5,10. I have read that some People have tested positive for up to 120 days. Do you think I should dilute? Also can b12s be detected and will cause a void?

    Thanks so much

    • Mary Jane says:

      Typically 90 days is more than enough time, but everyone is different so there’s no guarantee. Run down to your local pharmacy and pick up a test kit so you’ll know if you should be diluting or not. Cheers!

  • John says:

    I have an upcoming drug test on the 19th. That would be the ten day mark of not smoking. I smoked twice one to two hits. I am of very small build with little body fat. Sweat quite a bit at work now in a high heat environment and drink plenty of water. Been taking niacin flush free for a few days and also did at home test that came back negative but don’t know how well to trust them. Any opinions?

    • Mary Jane says:

      Those test strips are the same thing that a lab uses – unless they use a GC-MS test (describes in greater detail in the article above). In the end, nothing is 100%, but I trust those tests pretty well. Most have a 99% accuracy rate. If you’re still nervous, you can take 2 or 3 tests. The likelihood of all of them producing false positives would be rare. Best of luck!

  • John says:

    I’m a chunky 29-year-old who smoked for the first and only time on June 3rd and got as high as a kite. I don’t have a drug test coming up but will be on the job hunt pretty soon. It’s been more than a month, but again, I’m 5’8″ and like 235 pounds, so I haven’t been in a big rush to apply. I’m too lazy to exercise or try any of those other methods and am essentially waiting it out–all my friends think I’m being too fussy and can pass already. Am I good to go for a urine test in say, a week or two (this would be nearly two months since I smoked)?

    • Mary Jane says:

      My best advice is to pick up a test kit at your local pharmacy. They’re not too expensive and it’ll let you know if you’re good to go or not. Cheers!

  • Not me says:

    I have a simple question. Have a drug test coming up next week. I just smoked today lol i know. My question is i read ur article and a portion says if you know anyone with clean piss you can ask them for some. What about my wife??? Can i use female urine to pass my drug test??? Thanks in advance and a great forum for help.

    • Mary Jane says:

      I would avoid using the opposite sex. It can’t be detected by the typical strips, however, if it gets sent off to the lab they could possibly test for hormones. It’s unlikely, but there is a little bit of risk there. best of luck

    • NurseyFly says:

      The only gender-specific hormone that’s tested for is the Pregnancy Hormone & is regularly tested across genders, both to confirm an unknown pregnancy in females & spot substitution in male specimens.
      So, Recap:
      If you’re a Female, you can substitute either gender’s urine!
      If you’re a Male, you can substitute male urine & female urine-
      From any female who has NO CHANCE of being currently pregnant-
      OR who Recently miscarried, aborted, or given birth
      {& possibly even while breast-feeding}
      otherwise it’s FINE

    I am 27, 151 lbs, and work out doing heavy lifting about 3 hours for 3 to 4 days a week. I run 6 miles a week and have been drinking 1 gallon of water as well as 1 gallon of Gatorade everyday. I am a heavy smoker and usually dab. I stopped smoking 11 days ago, and will be having a urine and blood test in 11 days.If I keep this up, will I test negative? I’m really worried I won’t! Please let me know!


  • DumDum says:

    I’m a heavy user (3-4x’s/day) for about 6yrs now, I used UltraKlean and failed miserably needless to say I lost the job. Now, I’ve been smoke free for almost 2 weeks. My problem is that now I will be tested for a new job, but this time it’s a blood test. I have been drinking lots of water with Cholorphyll, I don’t exercise, but I weight 100 lbs and have a very fast metabolism. How much longer should I wait it out for my blood test to come back clean. This is beyond stressful, please help me:)
    Thank You MJ,

  • Michelle says:

    Is there a specific kind of niacin 250ml that need to by?

  • Michael says:

    Hey great info. Here’s my personal scoop:

    I’m 30 years old (which I’ve read didn’t bode as well for passing as quickly), 5’10 and 185 lbs. I’ve always been an athlete and still exercise 5-6 times a week or play sports at minimum an hour when I do. I’ve been drinking tons of water, partially because I want to flush but also because I literally need it due to the frequent activity and the end result is I’ve been pissing crystal clear for two weeks now. Plus where I live in Cali it’s hot as balls so I’ve been sweating a ton when I’ve been active. Back in the day this level of activity would have got me absolutely shredded but now it just kinda maintains my said weight since the metabolism isn’t what it used to be. I’m fit for my age but definitely store a little around the belly. I’ve been clean for 26 days, and I have the option of putting it off for possibly up to a week max. Test is scheduled for tomorrow, but pending a home kit result today I may postpone. It’s for a term life insurance policy, so it isn’t absolutely essential but I’m afraid it’ll effect my driving insurance rates since they’re linked through the same company. Generally I was smoking snapper bowls from the bong 5-7X a day with mid-grade weed. Definitely not top shelf or medicinal quality. Other factors about my health would be that I’ve in the last week used C4 50X which is a pre-workout supplement to help train for some upcoming athletic events, but it has an upside too from what I’m reading due to the niacin within it (I’m almost worried that even though it’s over the counter from GNC it may trigger a test failure for resembling something closer to an amphetamine) which as you stated has mixed reviews. The other concern is that side I’ve been so hydrated and my body is acclimating to that intake (I have insatiable thirst and pee like a race horse lately) that I’m worried I’ll pee too diluted/clear and fail. Will B12 do the trick or should I not hydrate as much the day of? Thanks for the help!

    • Mary Jane says:

      If you have the option to postpone then I always encourage you to do so. The b12 should do the trick, however, it’s best to test it beforehand. The test kit you mentioned is going to be your best indication. Best of luck!

      • Michael says:

        Alright, so the home kit test said negative. I think. BARELY. The faintest of faint lines appeared, almost to the extent I’m afraid someone with awful eye sight wouldn’t see it. My lady had to reallyyy focus, but she caught it. I was hoping to test under the conditions I am hoping to when I undergo the real deal- with diluting, using B12, etc. Issue was even after B12 I was still peeing really clear, enough to where I think it would warrant a retest/failure. So I waited about 3 hours with no liquid intake to ensure it was more yellow, which it was but obviously not with the optimal dilution. Also drank two Red Bulls prior to the 3 hour liquid-fast. I was only able to postpone a few more days- 36 hours from now to be precise. What can I do to make it look more natural with dilution- I’m wondering if particular food intake or more B12 would help? Also, any suggestions on exercise- I’m wondering if intense cardio or sauna tomorrow would be beneficial since it seems I’ve almost knocked it out of my system (judging by the faint line), or if that would release the detectable metabolites back in to my system and screw me. Guidance in the home stretch needed, thanks!

        • Mary Jane says:

          Stop working out once you’re within 72 hours of the test. THC is held in your fat so you want to stop releasing it before the test. If you’re still peeing clear I would try taking a bit more b12. If that doesn’t help then you may be over diluting. Best of luck!

  • Finger cuffs says:

    Female 5’8″, 225, do 45 min on elliptical 4-5 days a week. Smoked 3-5 small bowls of decent daily for 7 mos. Last was 7/15 and for that last month, it was less than 3-5, more like 1-2. I have a pre-employment screen 8/4. I’ve taken two Dollar Tree tests and I had faint double lines on both. Regardless, I am completely freaked out. Drinking lots of water. Thoughts?

  • j smoke says:

    Hi, I am a heavy smoker. I smoke about 4 blunts daily and some one hits out my little pipe. I was on probation and getting watched . Passed with a little bottle i got from the camping section at walmart . Put tin foil over it and put it up in me. I put it inside my panties until i walked in and then i inserted it like a tampon. I wore a long shirt and when i was holding the cup i poked a hole thru the tin foil with my finger and the rest is history. 🙂 I got a little pee on my hand but you got to do what you got to do. I am here to share my info but i also need help. I am going back to court and i suspect they will drug test me. Since i will be in court, I do not trust faking it because I feel the temp will be hard to maintain for that long. I want to know which method will work the best for me. My drug test is in 12 days. I am 110 lbs, 5’1 and like i said a pretty heavy smoker . with the help of my friends I have narrowed it down to the herbal clean qcaps and drink and the sure gel method because that is how they have passed theirs. i need help choosing which one if not both that i should do and i will also be pairing it with working everyday. I am willing to do anything , because i refuse to go back to jail. please help me.

  • Stuff man says:

    HI I’m a pretty light smoker. I usually smoke a bowl weekend’s and occasionally during the week. Recently I got a new job and had the initial screening and 4 weeks later it came back as neg. Dilute. I used a product called terminator gold 60 and followed the instructionI think I had to much water and from what the guy at the head shop told me there is a step I needed to skip. Needless to say the hr manager came to me after 4 weeks telling me about the result and I would have to retake the test. This was 8/19. I smoked camping the previous weekend 8/13&8 8/15 probably a bowl or less both days. The last time I smoke was 8/24 and only like 2 hits of some good stuff.
    After I found out I got some test kits, a cleansing pill kit, started drinking tons of water, no alcohol, eating clean, and drinking creatine protein drinksin like a health shake. I’m also going to the gym andsweating in the sauna for as long as i can stand. I havelso been taking vitamins and niacin. So far I have tried a test kit every morning for the past 3 day and all came up negative. I know the test will be going through a lab.

    I’m 5`9″, 176lbs, active, medium metabolism. I’m doing my best to post pone this next test but I’m sure my time is running out. I have read the info above and other places. I’m wondering if I will be good and if trequired is anything more I can do? I’ve been stressing like crazy. I don’t consider my seleven a moderate smoker. Thanks for any help I can get.

  • Stuff man says:

    Just to add I mainly smoke on weekends and usually only a few hits. I also have a vaporizer. Usually I’ll pack a bit and be good.

  • Runner187 says:

    I found out a few days ago I would need to do a pre-employment test. I smoked once on the 16th. One tiny girl sized dab and went to bed. Didn’t even eat that night because I was exhausted from work. I smoked a few times ten days before over the weekend but mostly I have been clean since July 1st. I have been sweating and doing a juice cleanse to burn some fat (don’t have much to burn, just those stubborn spots). I’m 5′ 1″ and 120 lbs at my heaviest. I went for a good sweaty run this morning and passed a home test this afternoon. What are the chances that I could still test positive for my test if it happens this week? My pee is by no means clear, it definitely has yellow color to it so I don’t think I over diluted…idk, just paranoid. I’m totally done with pot after this. Not worth the stress.

  • Lola says:

    Hey there,

    So out of nowhere my boss made me fill out some address information and asked me if i was good for a drug test. I said yes however i had a tiny bit a pot brownie the nite before the test. I usually smoke the oil. But i havent had enough lately about a week or 2 i barely had something to smoke. I workout about 45 min. To an hour everyday. I am fit or have less body fat. Drink a lot of water eat just salads mostly. Been vegan for a while now and i stay away from everything not natural or processed. Before i went to the clinic i drank as much water i could drink. But it was a very short notice i didnt even know i would be tested for work this is very upsetting. Cuz I literally just started working there. So what do you think would i be positive with it?
    Thank you so much.

    • Mary Jane says:

      Hard to say. You could go pick up a home test kit. If it’s positive now then it was probably positive then, however, the water dilution could certainly have swayed the test.

  • Fake name joey says:

    Hi I smoked on Friday and I have to take the test this Wednesday for a job. I bought multivitamins and b12 I still need to get creatin but should I get niacin too I’ve been drinking a lot of water since Saturday so much I threw up haha. What would you recommend use the dilution method with the niacin or it a lone and could you please give me some steps I need this job

    • Mary Jane says:

      You can do dilution and niacin at the same time, but please be careful with the niacin. Take small doses according to the directions on the package, because that stuff can mess you up – same with the creatine.

  • Desperate says:

    So here’s my situation: I’m a heavy smoker (multiple times per day, every day; I personally go through roughly an ounce a month) who just received a job offer of a lifetime. I need a secret clearance which will, of course, include a drug test. My last puff was Monday morning; it’s now Sunday. I’m about 6’0″, 150 lbs. and I’ve always had a fast metabolism, but I’m very out of shape for my size/body type. Other than spending a few hours on the beach 2 days ago, I haven’t done very much sweating, though I’m thinking about going to a sauna in the next day or two. A friend of mine suggested an ionic detox foot bath, which I will probably try as well.

    Another friend who had to beat a drug test not too long ago stands by Qcarbo 13, though I’ve read mixed reviews online. He also smokes considerably less than me. He suggested cranberry juice and aloe juice too, which I’ve been drinking in moderate amounts, and will continue to consume leading up to the test. I heard about the diuretics thing a while ago and someone suggested Midol, so I’ve been taking that as well as a Super Cleanse dietary product by Nature’s Secret that I saw at Whole Foods ( in addition to drinking plenty of water.

    I’m on the fence between sneaking in someone’s else urine and trying to pass on my own. I obtained some clean urine from another dude I know on Thursday. (I tested it myself; it’s clean.) It’s currently sitting in my frig, but I’m worried about how long it will be good to use. One of my roommates also doesn’t smoke, so I could get probably get a fresher sample if worse comes to worst. Another friend of mine, who helped get me the job and works for the company that offered me the job, snuck in some 5-day-old urine (unfrigerated) that wasn’t his, and he ended up getting hired. He gave me the same container he used and has been coaching me through the process. After reading the article and a good portion of the comments section, I’m thinking I might be able to get by on my own with the water + B-12 + creatine + niacin + soy lecithin concoction, along with vitamins and more cranberry juice. But I’m a worrier, so taking a drug test on a 7-10 day break after years of daily marijuana use gives me some concerns.

    Mary Jane (and anyone else that would like to provide input), what would you suggest?

  • Damn says:

    I have Quick and Clean synthetic out of Tempe Az. I have a ya for pre employment in Oregon. Anyone heard of this brand?

  • Joe says:

    My friend passed a test at concentra in VA sent to quest diagnostics using clear choice sub solution on aug 25. was asked to empty pockets but checked no further. Practice with your Temps he was closer to 95 then 100 and was freaking out. The sheet says check if between 90 and 100 but the wrong tech may have made him go again can’t say for sure tho.He didn’t take the heating powder in with him just used to heat it before the test luckily he dosent think the tech even really look at it. He bought the leg strap clear choice sells but did not feel comfortable using it after practicing. Made a small bag using a sock. Used some string and looped it around his pants button so it hung right in front of his crotch and was super accessible. pulled the whole thing off before he even finished actually pissing in in the toilet. This may of been why the tech had no suspicion that something might be up and barely looked at the sample. If he tried to add more heating powder in the bathroom it would of taken substantially longer and probably caused more scrutiny of the sample. His advice practice practice practice and more practice. Practice keeping your Temps and get an idea of how much it will change over how long, just use some water in the supplied container. The leg strap seemed to keep temp better. Practice the delivery of the sample in to a cup as quickly and quietly as possible. Practice wearing your transport system so to not look awkward when walking or siting. In the future he will probably practice with hand warmers to keep the sample at temp, and only use the heating powder if temp is substantially off right before delivery. I hope this helps somebody. Drug tests suck

  • Tictac says:

    I was a heavy user of medical cannabis, I’ve used cannabis for several years, I’m 130lbs 5’9″ and haven’t used for 2 weeks, I have a urine test at work on September 20th which gives me 15 days, I have been told by my union that if I do a at home test and pass I can do my work test sooner so I can get back to work sooner. I was in a motorcycle accident last year and used medical cannabis to treat my chronic pain. I am now using keterolic (toridol) I would prefer to continue to use medical cannabis for my pain but it is no longer an option. I guess the question is will I pass. I have to pass or I lose a job that pays $30.00 per hour and that is just not an option. Thanks for any input

    • Mary Jane says:

      All I can really tell you is to grab a home test and take it before you go to the lab. Typically that is enough time, but everyone is different. Best of luck. Cheers!

  • Henry White says:

    I haven’t smoked for 25 days, am of slender build and exercise and hydrate regularly. I gave my 4th void of the day having stayed very hydrated for 48 hours leading up to the test. What is the likelihood that I passed?

    • Henry White says:

      I also took a few home tests of varying prices before and after the test. I passed all of those.

      • Mary Jane says:

        If that’s the case then I would say you have an excellent chance of passing. It is possible to have a faulty test, but unlikely if you took multiple tests. The homes tests use the same technology as the labs (unless it gets sent off for full testing which is rare considering the cost).

    • Mary Jane says:

      It sounds like you have pretty good odds, but I could never say for sure since everyone is different. Best of luck and thanks for checking out my blog.

  • Daisy Jane says:

    Love the write-up! Very informative! Wanted to add some information done by a pharmacist in a lab to test the best dillution methods.
    “If you are a small time user 1-2 times per month and have low body fat you should be clean within 2 weeks. If you are a chornic user it could take up to 6 weeks to detox. The metabolites of THC are lipid soluble, they are stored in fat cells… All those herbal extracts mentioned [GNC detox] are tested for first, before testing for illegal drugs, and may be considered by some labs to be a positive immediately. Now I can tell you as a user and Pharmacist who conducted experiments in a lab what does and does not work. You must detox using water. Large amounts of water must be ingetsted started at least 36 hours before the test, up to 1 liter per 14.25kg of body weight per 24 hours. You must also supplement with creatine monohydrate, a bodybuilding supplement found in healthfood stores, at a rate of 1 teaspoon per 14.25 kg of bodyweight. Just mix it with your liters of water. A prescription diurectic called Furosemide should also be added to this water/creatine thearapy at a dosage of 1 mg per kg of body weight per day administered in 2 doses, AM and afternoon. The day of your test you should avoid excess physical activity. You should also take Super B complex vitamins as well as Vitamin C several times on the day of your test. This will provide the color to the urine so that it does not appear as dilute. When you donate, urinate for a short time then hit the cup about 1/2 way through urination. Cranberry extract may be added to the detox therapy above if you are concerned about kidney function while using the creatine monohydrate. If you get a call from the testing agency inquiring about the creatine in your urine, simply tell them that you lift weights and jog and do use performance supplements.”
    Sorry it was long, but I thought this was important to include a dosage amount based on your specific body weight. May we all pass our tests with flying colors henceforth and forever more! #legalizemarijuana

  • Abigail says:

    Daily/evening smoker, 2-1 hitter tokes just before bed, for past 2 years. I believe pot is considered medical grade, but is pretty strong. Last smoked 1 day ago. 5’5″, 200 lbs. Drug screen in 6 days. Exertion (other than walking) is not an option, for health reasons. Plan to do high fat diet for 3 days prior to test with Niacin, B complex and mild dilution the day of test. Opinions or suggestions appreciated.

  • Little big man says:

    Ok I have a pee test in a couple of days it will be a total of 18 days smoke free. I used to smoke a joint every day after work I’m about 5’6 165 lbs I did a gnc complete body 7 day cleanse and some exercise with some sweating and a little strength training what do you think?

  • Little big man says:

    Oh and it will be a test at 20ng since I failed the last one I just have to pass this one so I can go back to work

  • Elizabeth says:

    I took one tiny hit last Saturday, the 17th and have not smoked since. I would say that I am an infrequent smoker, last time I smoked before that was about 5 weeks ago and again a tiny amount. I used to smoke regularly, as in three or four times a week about three months ago.

    I have a drug test this upcoming Monday the 26th evening time. I have been working out like crazy, averaging about 6 miles a day. I’m a pretty active person, 4’11 and weigh about 108lbs. I have also been drinking a lot of water and cranberry juice, along with taking cranberry pills.

    I had also taken a at home drug test and tested negative but never know with the accuracy on these tests.

    Do you think I should start niacin as well? slash am I screwed?

    • Elizabeth says:

      I have also been reading online that I should abstain from working out at least 3 or 2 days prior to the drug test. Is this true? I feel like the more activity the better.

      • Mary Jane says:

        This is true. If you are more than 72 hours away you should work out and eat lean meals. Once you get within the 72 hour mark stop working out and start eating fatty food like cheeseburgers. The reason is because THC is stored in fat. Once you get close to the test you want to trick your body into holding all it’s fat in and not releasing the THC within.

    • Mary Jane says:

      I would put a little more faith into the home tests – especially if you’ve taken more than one. It’s possible to have a bad test, but it’s unlikely for multiple home tests to produce false negatives.

  • JimBob says:

    I am 6’1″, 190 lbs. I work out once a week for 30 minutes. Nightly user from 2015 to September 6, 2016. 2-3 bowls before bedtime. Prior to test, took detox pills from GNC with a ton of water daily since the 6th and still tested positive on home test on about Sept. 15. However, I smoked resin on Sept. 18, one time, then abstained from any more delicious Devil’s lettuce. Had an interview on September 12, 2016. Drank tons of water up until drug screen day (September 26, 2016) and have tried to eat veggies, almonds and fruit, but did have some pasta the night of Sept. 25. On Sept. 25, I drank QCarbo32 as per instructed and two hours later passed a home test with two solid lines (negative). Continued to drink water the night before and day of drug screen. Day of drug screen, I drank another QCarbo32 and repeated the same steps from the day before. Drank QCarbo32 at 1 pm, drug screen at 3 pm. Later in the evening (~ 8 pm), I took another home test and had only one solid line (positive). MJ, or anyone else out there, do you think that since it worked the day before, it will have likely worked on the actual drug screen and that my positive result is just because I was outside the 5 hour window? Drug screen is through AllOne or Altere. In hindsight, I should have tested right before I went in for drug screen for peace of mind. I will try to follow up when I get my results and tell the rest of my story… Good luck to all of those out there. #schedule1really? #invasionofprivacy #legalizeit

    • Mary Jane says:

      I haven’t used that exact detox, but most of them have a very specific timeframe that they work for. It’s very likely it had just worn off by the time you took the test. Best of luck 🙂

  • Bob says:

    Hey there MJ. Let’s start by saying I’m 5’6 117 pounds , fast metabolism. Didn’t start working out until I found out yesterday I’ll be tested in 30 days for court. I was a heavy heavy user user , concentrates mostly. I smoked daily for almost 2 years. I’m completely abstaining from weed, going to start drinking lots of water, exxcersizing as much as possible , drinking lots of green tea and cranberry juice. Also going to do my best on eating a high fiber diet up until 3 days before the test. Are there any other ways you would recommend to help me detox since I have 30 days exactly?

    • Mary Jane says:

      Sounds like you’ve got 1most of it covered. Grab some test strips. If you’re still testing positive when the test gets near consider doing some dilution, but be careful not to overdo it. Best of luck!

      • Anonymous says:

        Hey MJ any tips for dieting or amount of excersize I should do to help me pass by 0ct.27? In reference to the 5’6 117lb post

        • Mary Jane says:

          Eat really lean meals and exercise as much as possible up until 72 hours before the test. Once it’s 3 days away start eating fatty foods and stop exercising. Best of luck!

  • Me says:

    Has anyone ever used detoxify green clean herbal cleanse? I have a test Monday at 1:30. I stopped three weeks ago to the day today. Intake of water and cranberry and coffee(can’t live without coffee lol) use everyday. Startedmultivitamin, b complex pill. Eating plant
    Based healthier diet, not a big exerciser, 5″3 135lbs, not a lot of body fat. Tested at home and tested with a very faint negative line yesterday. I Still want to take the drink I purchased,do I stand a chance?

  • Scaredy-Cat MJ says:

    Hey all! So I’ve read this website back and front for the past month because I’ve been so worried and I’m back to finally give some insight and maybe request some info as I await the results of my drug screen for my dream job. Also, I wanted to give details about my description and smoking situation as that really helped my plan of action as I read almost all of the comments (so thanks everyone!)

    -Female; 23 y/o; 5’5″; ~142#

    -I wouldn’t call myself “fat”, I’m actually in the normal range for my height but could definitely stand to exercise more than I currently do, I’m quite sedentary. With that being said, the fat I do have, I carry in my stomach and thigh area which worried me about the THC metabolites being stored in these areas, as opposed to someone who regularly exercises and is lean w/ muscle.
    -It has officially been 3 weeks (literally as of today) since my last hit of the pots and the month before that I smoked maybe a handful of times when friends came to visit, but not nearly as much as the prior two years during my undergrad career….I smoked every day, A LOT, but I obviously don’t need to justify my reasons here 🙂
    -Three weeks ago I started taking niacin on a regular basis, drinking a lot of water, and attending a few hot yoga classes (that will really get you sweating). About two weeks ago I started using at home test strips that were the 50ng cut off level (cheap but well reviewed ones I bought using Amazon Prime) and I achieved VERY faint lines for negative. This was good news, bc any negative is still a negative. I got a 12-panel screen last Wednesday since my initial drug screen was the following day (I wanted something a little more trust-worthy just in case). I took this test in the evening and it came back negative. STILL GOOD NEWS. Unfortunately, when I took my legitimate drug screen on Thursday, I got word on Friday that it was “diluted” (I drank a little bit too much water/coffee). To my job this looked sketchy (and freaked me out a lot) but I remained positive and was told I would just have to retake the test before I could start.
    -Fast forward to today and I bought a 4-panel at-home kit (couldn’t find a THC only one) and saved it to take when I woke up. This is where the advice comes in for not using the first pee of the day. DO NOT USE YOUR FIRST PEE OF THE DAY. Today, I had a POSITIVE result, so naturally, I am up in arms before heading to the testing facility and drinking a little coffee to try to pee again for another at-home test because my nerves were all over the place. I took a few b-complex vitamins today knowing that would help with color and what not. I finally found a THC-only panel drug test to take before going to the facility (in hopes of calming my nerves). This came back NEGATIVE. Now, as I sit at home and wait, I am confident that it will be negative at the lab, as long as it doesn’t come back diluted again. It was perfect in color, but my QUESTION pertains to how well the B vitamins fool the lab into believing the sample is not diluted (due to over-hydration).
    -I will update with any results but I wanted to emphasize that TIME is really the only factor that will save you. I took a lot of Niacin, drank a lot of water over the past few weeks, and stuck to an almost zero-fat diet (fresh veggies, especially ones that helped detox the liver, etc.) STOP SMOKING. YOU CAN DO IT- IT IS POSSIBLE. I hate saying it, but if someone knew how much I smoked they would most likely assume I was addicted, and to each his own, but I definitely should’ve stopped sooner rather than later and now I’m sitting here at home waiting to see if I get my dream job. It’s a terrible feeling, so please, make the effort and it will hopefully be worth it….

  • Joe says:

    I last smoked on 10/10. My wife suddenly decided to sign us up for life insurance. Dumbass me didn’t realize they’d be doing tox screens during the exam. The exam date will be on the 26th, 16 days after last smoking. 6′ 185 lbs and very active. Just ran a marathon on 10/8. I smoke around 5 pinchies a day of pretty good weed. With exercise, cranberry juice, water, b12 will I be likely to come back negative? I’m a closet smoker, and my wife will raise serious questions if I come back positive for THC. I also plan on “faking” a bad headache the day before so in case it does come back positive I can use the ibuprofen as possibly giving me a false positive and ask if they can retest (after all a marathon runner can’t be a pothead). I think another week and I should be absolutely golden. Any other suggestions? Are life insurance tests more or less extensive?

    • Joe says:

      Forgot to mention I naturally drink 1-2 20 ounce cups of coffee a day and I try to intake 100 ounces of water daily. I’m assuming my natural lifestyle will make me the type that will be cleaned out really quick and I’m constantly doing many of these detox techniques anyway.

    • Mary Jane says:

      ibuprofen would not creat a false positive for THC, so I wouldn’t even try that. Grab some home test kits at your local pharmacy and give yourself a test before going in. Honestly, since this is something you signed up for and aren’t require I would just have the whole thing postponed.

      • Joe says:

        I was able to delay it. Looks like I’ll have about another week. Should be right around the 30 day mark when I take the test. I’m fairly certain I’ll pass, I’m just curious if you have any input as to what levels they look for in insurance exams? Is it still just 50 Ncg? Or will they drop you if there’s any level detected? I plan on picking up some test kits and the actual med exam isn’t scheduled yet. I’ve been able to delay it until now but I think it’s going to end up being next week. Hard to keep delaying without raising any more red flags with my wife. Thanks for any input.

  • Brianna says:

    Hi, I got a saliva test coming up, and I normally smoke maybe 2 or 3 bowls a night of mid. I haven’t smoked in about 4 days, do you think I’m safe?

    • Mary Jane says:

      Most likely. The best way to really know is to pick up a saliva test kit. You should be able to find them at a pharmacy, and they’re also available on amazon.

  • Another Guy says:

    I’m so freakin happy right now!!! I’ve just got a negative test result *jumping round the room*

    My story is a little complicated n I’ll try keep it short n sweet.

    Basically, I was stopped by the police and swabbed, it came back positive (hadn’t cleaned my teeth that day, it was a busy day hadn’t drunk much and only had half a nana). Cleaning your teeth and using mouthwash should be enough to pass one of these, anywho, was arrested and dragged down to the copshop. I wasn’t high and hadn’t been for several hours. I shat myself and put on a big thick jacket and sweated so much I stank of weed. The doctor was late for the blood test but to my shock!!! It came back negative, no further action taken.

    In this time the Jobs worth had decided to tell the DVLA I was a persistant misuser without any evidence, while I was on holiday they sent me a form to fill in asking what drugs I do. As I wasn’t there to receive it, they revoked my licence through non-complience and to get it back I’d have to do a medical involving a piss test.

    Although the copper was somewhat right on the persistant misuser bit, I really only smoke a tiny amount, less than a g a week. But it’s been my whole adult life, never a day without in over 10 years. So I began to shat myself some more. I decided to give myself a month without but this is much harder than originally anticipated.

    It’s now the 29th October n I stopped on the 24th, so 6 days. I have my medical on the 9th. I was getting positives up until today (with a little added dilution is was still kinda yellow but I’ve never had strong urine as I drink a load of water and cranberry juice but not a lot else). Any way this is good news because I’m getting there.

    What I have done to achieve this is? Biking miles every day, kids in the trailer and dog running along side. Taking the kids to the park and working up a sweat, eating pretty much just fruit n veg, very little carbs or gluten or dairy. Lots of sleep and lots of worrying which makes my heart race and sweat every time I think about the looming test. I am very small, 5’2” with very little fat. Always had an insane metabolism. There’s really not a lot of fat for the THC metabolites to hang on to. The only place I had fat was my butt and thighs which, with all the biking has made it turn into muscle. That’s about it really, I s’pose it’s natural detox with lots of exercise.

    I know everyone’s experiences are different but I’m just so chuffed there’s a chance to get my licence back. I thought I’d be testing postitive up until the day but I’m not and I couldn’t be happier. Speaking to other friends with bigger builds it’s taken 9-10 days which isn’t really much in comparison, so anything is possible.

    Thank you for all the testimonials and research and great article!

    My mind is finally at ease

  • Kel says:

    Thank you maryjanesdiary first for all of the great info here, and the thoroughness. I want to be thorough as well so this may be lengthy. I am starting a new job soon and of course they wish me to take a drug test. I am a moderate smoker, I maybe have a bowl a day on workdays, 2 on weekends. However I do skip days occasionally and I have not been a habitual smoker until about 2 months ago.

    I am a 28yr old woman weighing about 250lbs, so I’m not lightweight which made me worried about the thc staying in my fat cells. I found out on a Friday evening that I would probably need to take a test, and the following Monday (today) I was told for sure that I would have to take it. During those 3 days (including Friday) I have abstained from smoking and I bought the time-release type of Niacin at the drug store. This type does NOT cause the flush because of the time release aspect, but I was banking on having at least a week to take them every day. I took one 250mg pill Friday evening and I took 3 pills throughout the day on Saturday and Sunday for a total of 750mg per day. I staggered them throughout the day to try to keep my body continually processing the Niacin. Today (Monday) I have taken 2 pills so far, one this morning and one around lunchtime for a daily total of 500mg. I will take one more tonight totaling 750mg.

    I have also been doing a lot of heavy lifting and loading at work which is not the typical excercise for me. So while I didn’t “work out” exactly, I have been sweating and pumping my blood much more. I also have been drinking extra water every day, usually about 2 liters more than normal. I had one 16oz bottle of cranberry juice; specifically Ocean Spray Pact which supposedly has “the power of 50 cranberries” according to the bottle. I purchased more juice today, a 60oz bottle of 100% juice. For those who haven’t noticed, juice like this is not actually 100% cranberry juice but has other fruit juices included. This one DOES have cranberry juice listed the first ingredient which means that is the main ingredient.

    Anyway, when I bought the juice, I also bought an at home test kit. I have been nervous about the test because of not only my weight, but the fact that I did not have much time before the test. When I took the test this evening, I made sure to follow the instructions carefully. I had already drunk almost a liter of water before running to the drug store, so I was ready to go as soon as I got home. My urine was light yellow (the first day I took the Niacin my urine was crystal clear, but it has had at least a little color every time since) and when I put the test stick in it took about 3 minutes for both lines to appear on the tester. The instructions say to check after 10 minutes, but after about 6 minutes the indicator said that the test was complete and ready to be ready be read. I had two lines, and even though the line was faint it was there! I waited until the 10 minutes were up to be sure, and it was still good, both lines were visible.

    I definitely plan on continuing to take the Niacin and drinking my water and juice. I may even take another at home test tomorrow or the Wednesday before the test, but I feel pretty confident. My clinical test is Wednesday, so not even a full week will have passed since I stopped smoking. For people who smoke a lot more the results may not show up as quickly but mine have been successful within just 4 days!

    MaryJane, thank you again and I hope this helps! Please let me know if you think I’ll be good for my test or if you think I might need a little something more.

  • S Roggan says:

    Hello! Thank you for this article!

    I am 5’8 and 165ish lbs. I last smoked on November 15th and being tested on December 9th – 24 days. I’ve been working out for an hour and a half to an hour everyday since November 28th. I’ve also been drinking a lots of water every day as well as taking 1000 – 1500 mg of Niacin everyday. It is non flush niacin, though. Do you think I will pass? This is for a life insurance test, not a job.

    Thank you!

  • longtime says:

    When I was younger and metabolism was high, I had 10 days to get clean. I smoked like bad, chain smoked. I used niacin and b vit, for 6 days , started taking 8 a day two every 4 hours and 1 b. drank cranberry drink a few, a little water and then back to dew. I passed clean. Now im 140 lbs been clean for 30 days, do not exercise and test home and positive, unless I drink a bunch of water. then faint line. I used maybe 2-4 tines a week 4-6 hits, for 3months. Like I said been clean for 30 days , test still positive. But thc has a half life. The amount they first tested me for came back so high they said 796. so every day that goes down 1/2. so it can take up to 3 months or longer unless you deluite and use something. I also used rubber with someones else clean in it and put it you know where, which is great for temp and when no one watches. I am doing the stinger detox , last for 5 hours, but also niacin and b12 for a week before, and cranberry. it will make your pee bright green, so good for a first flush and then water all the time, and the stinger detox day of with water. will test continue through out , hope a faint line pulls up. but also buying a good test to test before I go with the detox. If comes out pos, lots of water,,should pull up a faint line, ugg..just to let you all know niacin and b12 does work if your skinny and drink a lot of cranberry and water ,, stay away from milk dairy and sugar,

  • J says:

    Found out that I had a drug test in less than 24 hours. Much like the rest of you, I researched like crazy trying to figure out a way to pass. Here is what I did.
    1. morning of test at 6:00 AM. I mixed one packet of Sure Jell with one gallon of water and began drinking.
    2. Along with drinking the Sure Jell mix, I used Purity Labs USB, which is a bottle of 10 pills you take with a lot of water.
    3. Finished the gallon of water by 0700, had urinated twice by this point.
    4. Drank maybe another quarter gallon of water while driving to work, and when I got there. Urinated a third time at work.
    5. Took the test at approximately 8:30. Gave a mid stream sample.
    6. Got a phone call today telling me I failed
    My test was sent to a lab. I wish either I had taken a chance with synthetic, or I wish that I had not fallen in love with MJ years ago. Might be different for others, but that is my outcome. Just ruined a 13 year career. Good luck and best wishes all.

    • Mary Jane says:

      I’m so sorry to hear this. I’m sure you’ll be able to start again, but I know it feels like crap for now. The worst part is I’m sure you were a terrific worker (why else would you have made it 13 years). It’s just not right for a company to let a good worker go because of a harmless plant. My thoughts go out to you, and I wish you all the best!

  • A little stressed... says:

    MJ, really appreciate this forum & all your insite. Been basically a daily smoker for about 4 years now.

    I think I’ve gathered all the information I need reading through all these Q&A’s. But I never came across my particular situation – and you still may not have an answer. However…

    I’m with a company where I’m shifting positions slightly. My new position requires getting my CDL license… which requires a complete physical. This isn’t something my company is requiring of me… But simply a state requirement in getting a CDL license. My question is, since I’m getting a complete physical, I’m guessing I’ll be naked with a gown around me while they do this. I’m wanting to use the synthetic urine route, but I’m afraid I won’t be able to conceal it.

    Do you have any information on exactly what they do while getting a physical for a CDL license? I have heard that they will require a urine sample.

    And although I totally don’t want to do this… But is being able to put a sample up your rectum the same as putting it up your vagina – specifically for temperature? Ewww gross – I know!!

    Thanks in advance for your help…

    • Liz says:

      It’s not very safe to put things in your rectum because if it gets lost it has to be surgically removed… if you were you would need a sure way to secure it which I think they would be able to see. Good luck

      • NurseyFly says:

        @A Little Stressed-Yes, keeping a sample warm in your Prison Pocket is Just as effective as girls using their V.. um, Prison Purse
        -&More effective at Raising Temp to 98.6+ [Recall rectal thermometer?]
        {& added benefit of less embarrassing leakage!}
        @Liz-The chances of Anyone,[let alone an employable adult,]actually “losing” Any object,[let alone a 3+oz container of 98-100 degree piss,] past 2 sphincter muscles, then past the smaller, segmented, rectum&then far enough into your colon to require Surgical removal, are Astronomically Low!!!
        {nearly impossible, but let’s study those special people who succeed!}
        @A Little Stressed-Just to be Safe, & Sound, (& comfy, & uncaught too!)
        Make sure you Only insert a Smooth container, {Slowly/Using Lube}that
        does Not cause: Any Tearing &/or Bleeding of the asshole
        Or Sharp/Prolonged Pain of the asshole &/or rectum During OR After insertion.
        Try something thin, smooth &/or flexible to maintain body temp. while comfortably walking around/to the test site/sitting&waiting & Not Bursting! (condom, ziplock bag, child-sized Fleet enema bag) These are thin/flexible enough to keep under your arm-pit, strapped to inner thigh/under scrotum/directly on member, depending on if/how closely monitored you are, for temp. control, (&maybe a more comfortable spot, than the male G-spot…)
        Though a firm yet pliable plastic vial, bottle or container {Never glass or metal!}
        is Safe & holds temp best when pre-heated & then kept in a bodily hot-spot
        -but must be able to open & pour/squirt it quickly, quietly & discreetly
        (& if monitored, all w/out using both hands & look/sound like a natural stream!)

  • Liz says:

    I’m very nervous, in the past niacin (1000mg)tons of water and working out has clean my system in 2weeks. This time it’s 16 days even purchased “clean slate” from amazon and did a 7 day detox right after I stopped. Did research online and did work out this morning. Of course my test are coming back positive, last time I’ll purchase clean slate since I completed it yesterday. I worried I know my test is going to be completed by a very reputable company surscan. They do test in labs. I have quick fix but don’t want to use it if I don’t have too Bc I suffer from bad anxiety, that’s why I love to smoke it calms me down. Should I use the synthetic or just eat red meat like crazy and keep test myself and risk it with my extremely faint pink line (kinda think it’s my eyes playing tricks on me). I wish I found your site this morning with my original search. Also thanks to the guy who talked about Sure Jell I know someone personally that it worked for but now I don’t want to risk it, wish I could share the link from a girl who swore it work for her on five different tests. Thank you again!!

  • A girl says:

    I haven’t smoked in 3 1/2 months, gallon of water everyday and gym every single day. STILL NOT CLEAN. what the actual fuck

  • Person says:

    I have a drug screening*(says screening not test on my acceptance letter) next week for a software specialist position. I am wondering what the chances of the screening being a urinalysis are. I’ve got a friend who is giving me clean pee the day of the test. Got the bottle, hand warmer, etc. I’ve just been overthinking the possibility of it being a hair test. Any input is appreciated.

    • Mary Jane says:

      A screening is just another word for a test so it’s the same thing. It is possible to be tested in a way other than urine however it’s unlikely. Hair follicle tests are more expensive – not to mention racist (African American’s hair retains THC longer). If you’re looking for some extra peace of mind then you could purchase a specialized shampoo. Best of luck!

  • Pirate Botanicals says:

    Hey Mary Jane,
    Thanks for writing this article and thanks for reading my question. I’ve used synthetic urine once before and it worked, but I periodically do some googling to see if there are newer, better methods. I ended up here looking for a second opinion after reading an article on drugs and bad ideas that basically said synthetic urine is the only way to be sure you pass and it sounds like that’s the conclusion you’ve come to as well. Obviously, detoxing is a better option if you have enough time before the test, but to be prepared for short notice, you basically need to keep synthetic urine on hand if you don’t want to get screwed. I keep expecting to find some new, foolproof method that doesn’t require synthetic urine, and I feel like science is kind of letting me down here, haha. Have you heard of anything recently about anything, even something super experimental, that aims to replace synthetic urine as the best guaranteed method for passing short-notice drug tests? Or would you say the information in your article is still totally up-to-date?
    Thanks for taking the time to read my question, Mary Jane, and thanks again for writing this article! 🙂

  • this is a great site and i will pass test, and article on.thanks.

    • Mary Jane says:

      Thank you and you’re welcome. Best of luck!

      • Just nervous says:

        Just a little nervous. I hadn’t smoked for 10 days before my test. Did the carbo detox and my results came back diluted. Was asked to go retest. I did 2 days later. Those 2 days I did 1000 mg of niacin, water along with Gatorade/water this time. Day of test I took a multi-vitamin, drank a Red Bull, coffee, water and more Gatorade. I dropped about 5:00 pm on a weds. My smoking habits were 2-3 bowls a night. But, daily for 2 months. My scare is I haven’t heard from MRO and today I started my job. They stated in the morning that they are still waiting. My starting the job was based on passing. I wasn’t happy to know that she let me begin anyway. How long if positive will the MRO call. I feel like that’s what I’m just waiting for.

  • Griffin says:

    I have a question I have a parole urine test coming up tomorrow and I haven’t smoked in about 20-23 days. When I did it was for about 2 to 3 days a couple grams of some high grade kush. Do I need to invest in some detox or should I be OK just pissing regular? Oh I should mention I am a big dude 275 to be exact.

  • mdh says:

    I have a drug test on March 15th for my dream job. I found out today, February 21st. I had a couple of hits yesterday, and for the most part have been a daily smoker for almost a year. If i do niacin once a day up until my test while simultaneously taking B12 and drinking copious amounts of water daily and working out and tanning daily, do you think I could pass the test on March 15th?

  • Green Dragon says:

    Thank you Mary Jane for this great site and all of the information. It has inspired me to keep a diary of my two separate weekends use of cannabis and subsequent detection times. I intend to create a blog page to publish all of my results to try and get as much info out there as possible, but in the meantime wanted to get my first blog onto your page in the hope that my information can help people as soon as possible. So here is my first as yet unpublished blog entry. Once I have the results of my second ‘experiment’ I shall publish them here, along with a link to my blog page.


    I have decided to keep a diary of my couple of weeks of cannabis use and subsequent detection times for urine drug tests, as there is a lot of conflicting uncertain information around and very few first hand accounts. There are a lot of people who live in fear about failing tests for such an innocuous wonderful plant and unfairly ruining their lives due to losing their jobs or going to prison. If I can help with my experiences then I will be very happy.

    I have a job that random tests employees for drugs but have had some time off recently and took the opportunity to smoke some weed that I was offered. It has been a decade since my last use (I was a daily smoker and adored it) so it is certain that I had no thc in my body prior to these results. I bought some multi panel urine drug test strips from the internet and generally tested myself around lunchtime on the particular days listed, after a large coffee and a soft drink or two ie hydrated and not the first ‘dirty’ piss of the day which would contain more metabolites. Generally, my urine would be still yellowish when testing and not so diluted that it was clear.

    I am in my mid forties, stocky with a bit of body fat. Not fat, but could lose a stone or two. I am pretty active, and during this period did lots of walking but only a couple of sessions of real cardiovascular exercise, ½ hour running/swimming. So not sedentary but not a daily athlete either.

    During this period I exercised on a couple of days, didn’t on many others, didn’t eat particularly healthily, drank alcohol most days, and after the second weekend of using cannabis took some supplements that may or may not contribute to my subsequent detection times. The problem with cannabis use and drug tests is that because it’s fat soluble it stays in your system longer than other drugs. There are so many factors that determine how long it takes to get clean after using cannabis (eg amount used, strength of the cannabis, previous use, weight of user, age, body fat, metabolism, diet, exercise, hydration etc) that it is impossible to state for sure exactly how long it will take each person to clear the drug from their system. Add in other factors like use of other drugs and you can see that no two people’s results will be the same.

    I will repeat that my experiments are not under laboratory conditions, but simply those from an average person, with honest results, in the hope that I can help someone else who seeks information about detection times. I haven’t found much strong anecdotal evidence about cannabis and drug testing online so hope that my experiments can help. The widely accepted fact that any cannabis use will mean failing a drug test for many weeks or even months later has been challenged recently, and as someone who can’t smoke regularly because of his job I was very eager to find out if occasional use would be possible if on holiday for a week or two.

    My diary begins at the start of February with a long weekend of friends visiting and some smoking of weed.

    The weed I smoked was mostly two decent strength sativas- I was told they were sour diesel and super lemon haze but I have no way to know if they actually were those strains because I live in a country where cannabis is illegal so they were not from a dispensary or coffee shop, but they were definitely sativa dominant and cerebral as opposed to couchlocking)
    I also had some low strength indica and a little bit of medium strength hybrid in the first two days of my experiment. (I say experiment for the purposes of this report. The reality was green stoned euphoria!)

    I should also state that all of the weed was smoked through a small bong, and each hit was far from a full bowl. More a small pinch. I can’t say for sure but I estimate that over the first weekend (Thursday to Tuesday) I smoked about half a gram in total, and the second weekend (three days successive use) probably smoked just under a gram. I am writing this just a couple of days after my second weekend of heavier use and expect my clearance time to be longer than last week.

    So here we go. I’ll try and keep it to vital information only…


    2nd-2 hits low strength indica
    3rd- 2 hits medium strength hybrid
    4th- 3 hits decent strength sativa
    5th- 1 hit decent sativa, 1 hit low strength indica
    6th- nothing
    7th- 1 hit decent strength sativa

    10th (+3 days)- 50ng test- fail

    13th- (+6 days) 50ng test= faint line- a weak pass

    15th (+8 days) 50ng test= Strong line-definite pass. 25ng test= very very faint line- borderline pass

    I conclude that with light use of a couple of hits or so a day of weed over a period of five or six days, my system will clear and pass a 50ng drugs test in 6-8 days. Probably a day or two longer to pass a more stringent 25ng test.

    I believe that amongst all the uncertainty and hysteria about cannabis and drug testing online, my results agreed with those reports that light use (for me over a few days, with no previous tolerance) would indeed clear within ten days as some more recent reports suggest. I am curious about my slightly more extensive use the following week to see if the detection times are greatly increased by more intensive use over a shorter period of time (three days). If I was to guess, from my completely layman’s position, I estimate that I’ll start to test clean the second week after 8-9 days and become a strong pass (50ng) after 10-11 days, with a 25ng pass after 12 days. We’ll see…!


    So there we are. I hope this information can help people, and I will be back next week to let you know the results of my second slightly heavier use and subsequent detection times (it is currently six days since my last use and I shall be testing myself over the next week and report back)

    Cheers, peace x

    Hi again. Today I passed my second weekend’s

  • Leann says:

    I’m a 130 lbs female with very little body fat. I was hit with a random ds at my job. I’ve been smoking mj for years every day. Usually a couple hits twice a day. Lately I’ve been drinking a lot of red Bull which has b12 in it. I had less than 24 hrs to prepare for a test. So I started drinking water. Lots of water. I eat very little in general and in those hours before the test I ate light meals like salads, vegetables. I was peeing every half hour and I worked the night before the test. I work third shift. I took 4 aspirin at 4 am. 5 hours before the test. At 6 am I drank detoxify ready clean and also took b12 500 MG two at a time throughout the night. I followed the detoxify by 16 Oz of water as directed. I peed in a cup in front of a lab lady at 9 am. I wish I knew about the midstream golden rule. But I didn’t finish peeing in the cup, so it was beginning and mid stream pee that went in. The pee was golden in color. I took a test on Friday morning. The lab tech said results may be available by afternoon or 1-3 days. I just did it and don’t know my results yet. I have high metabolism. I also worked out twice the night before 30 min sessions. I’m freaking out right now. I don’t want to lose my income but hey Maybe it’s for the better. I will come back and let you know my results. Could it be that labs would try to process samples asap on friday? I was the second person to be tested that day. I would imagine they would take care of it asap same day instead of keeping a sample in the fridge over the weekend. What do you think about that?

  • C says:

    Disclaimer: desperate times=desperate measures, I, in no way shape or form think this is a healthy choice to make but I’ve seen it work—I’m a registered nurse and a friend of mine called me in a panic that her bf had a probation drug screen in two days, he was a regular marijuana user and had smoked that day. So she asked me to straight cath his bladder (insert sterile tube and completely empty his bladder) and use urine she obtained from someone else, clean catch specimen into a sterile cup, i did it in the parking lot of the place and done. Passed. His own penis, his own bladder just someone else’s urine, which is gross of course but hey, he passed!

    I’d like to point out flushing a bladder with sterile water is practiced in circumstances where necessary so the act of re inserting a liquid isn’t the concern, it’s the risk for infection due to 1) someone’s bodily fluid 2) bacteria from the cup or the syringe used to insert the urine.

  • Lexi says:

    Okayyy !!! so I am posting this because I am doing my third experiment with Certo to see if you can use it to pass drug test for probation.. I have been a heavy smoker for 6 years now and never stopping not even for tolerance breaks or anything like that! maybe about a quarter a week I use to smoke.. well my last day smoking was March 31st and around the 3rd I did a experiment with Certo and mixed a pack with 32oz of gatorade and drank about 2 liters of water.. this was in a 4 hour time frame.. failed all 3 tests I took from at home tests… Yesterday I did another experiment and started with water FIRST and had about a gallon of water, was probably peeing once every 15 mind about 7 times and then took one pack of Certo in a bottle of 32oz lemon lime gatorade and then drank 2 more bottles of water! My pee wasnt crystal clear but def was clear… I took another at home test and a REALLY REALLY REALLLY faint passing line showed up… Right now I am starting my 3rd experiment starting with water first and Im going to take 2 packs of certo instead of one…. My probation test isnt until May 1st .. so im hoping I can figure out how to get it just right to work… Ill post an update on how my 3rd trial run went…

  • Lexi says:

    Doesnt work for people who are heavy smokers.. Ive been a heavy smoker for 6 years and ive done 2 different experiments with Certo because I am on probation and wanna see if itll help me be clean and I cannot pass a home test at all .. my pee was crystal clear and I was still testing postive on home tests!!! I did it drinking a gallon before then in one hour time 2 packs certo in 32oz lemon lime gatorade then about another gallon after and peeing a few times and i failed.. I did this experiment twice so far and ive been clean about 10 days and its not working,, might try again after more days clean but idk its cheap but not worth it to keep failing

  • Annie says:

    I had a pre-employment drug test this morning and passed, and I only stopped smoking for 6 days. Just thought I’d share how I did it for anyone who is in a similar situation. First off I’m 5’9 and weigh 115 pounds. Moderate smoker (3-4 bowls a day for years). What I did was took 1000mg of niacin every day, drank probably 4-5 liters of water a day, and did a fairly heavy cardio workout once in the morning and once in the evening (like 45 mins of jogging or biking). They key is to really work up a sweat to get all those toxins out of your body, otherwise the niacin doesn’t do anything. Get yourself dripping in sweat and then rinse off. Additionally I got a bunch of antioxidant rich foods like pure cranberry juice and blueberries. Keep your diet healthy and avoid fatty foods. I also went to the gym one of the days and used the steam room after working out. I think the biggest thing is to sweat as much as possible. Get yourself an at-home drug test to test yourself before the real deal. This is what I did and I was amazed that it really did work. Hope this helps someone!

  • Rob says:

    Hey there,

    Just wondered what everyone thought about my situation. I haven’t smoked for about 55 days. So I’m sure I was clean at that point. But sadly, I slipped up 2 days ago (4/13 at night) and got drunk and took 1 hit from a bowl of some blue dream (probably like 22% THC). Kicking myself over it, because now I found out I have a drug test for a new job that could change everything. The test could be early as 4/19 but hopefully will be later and I’ll have at least a week or more.

    Do you think I could pass it as early as 4/19 (5 days basically)? I’m 6’2, around 185, and fairly active. I’m planning on drinking plenty of water, exercising everyday up to where I should stop, eating a proper lean diet, niacin pills and creatine every day. Also have test kits on the way from Amazon. Planning to take a mega clean (xxtra) the day of the test, and dilute with b12.

    I also have quick fix synthetic 6.1 on the way as a back up, but I really hate to use it as I know if they catch me it’s an instant fail and legal issues compared to doing it myself.

    Thanks for all the wonderful info on this site! The best I’ve seen around and a great comment section. I feel like I have a pretty good chance considering I was clean for a long period before and only took 1 hit. Assuming I’d be clean in about 3 days.

  • James says:

    I have recently passed a urine screen using the dilution method and adding niacin, creatine, B12, and various vitamins. I knew a needed employment but i couldnt stop smoking. I would smoke maybe 1gram a week. I also smoked 5 days before the test. I really wanted to use the substitution method but I got nervous because I had a physical before the screen. I decided to go with what worked for me in the past and that is to dilute and take supplements to replace what has been diluted.

  • Chelsea heeley says:

    I snuck fake pee into my court house to pass a drug test for my probation officer. I bought one of those tiny vodka bottles, filled it with a generic fake pee from my local 420 shop. I covered the hole with tin foil with a rubber band so I could just break the tin foil instead of dealing with the cap.
    I would not reccomened this. I did pass the test, but as I was in the bathroom I needed to use two hands to keep it there as my vag kept wanting to push it out and the test Lady came in and told me only one hand (saw me through 2 way glass) and watched me the rest of the time. Then the bottle fell out into the cup, and I had to get it back in without her noticing. I would not do that again o barely didn’t get caught the first time.

    Been pretty heavy smoker long as I can remember. Smoked at least 1 gram a day and probably more for years and passed test using niacin with 3 days notice for pre employment. I took about 1000 mg 2 times a day with plenty of water through the day. I am 5’9 and 145 lbs. Also have used quick fix with no problems. Good luck guys

    How accurate is the HPLC-MS test as far as finding out if the urine is real is? I mean, I get it that it will detect even minute amounts of THC if present, but in synthetic urine there is no THC.
    It’s the same case with clean urine. So is there a way that such a sophisticated detection method such as HPLC-MS or GC-MS would detect synthetic urine? Based on what substance?

    • Mary Jane says:

      It is possible, however, most synthetic urine brands are keeping on top of testing methods. Basically, theses tests can pretty much identify any substance within the urine. It’s synthetic manufacturers jobs to make sure they are adding all the proteins, etc. found in real urine so it will test the same. So, yes it is possible, but I’ve personally never had a problem with this. I hope this makes sense.

  • Amber says:

    From what I understand and I believe a lot of people misunderstand about niacin is that it doesn’t burn fat faster therefore detoxing the body. Instead, when taken in larger doses (at least 1000mg) it blocks fatty acid breakdown into the bloodstream. Therefore no thc is deposited into the liver or back into the bloodstream temporarily. Taking niacin has always worked for me and my boyfriend but the way we use it for a drug test is as follows: we take 1000mg in the morning and drink several bottles of water a day, then we take another 1000mg at bed time. Since your body burns fat while sleeping, if u don’t take niacin before bed then fat breakdown begins and thc is back in your system starting you all over again. We do this for at least 5 days prior to testing and it has never failed us. The niacin has to stay in your body consistently for the few days leading up in order to keep the thc from being released back in your blood/urine. Also drinking water to keep anything flushed out is key as well. This method has never failed us when done just as I’ve explained. No one can convince niacin doesn’t work.

  • Amber says:

    Oh and also, you shouldn’t excerise while trying to use the niacin method because excercising burns fat, which again releases the thc back into your blood. A lot of people take niacin and workout thinking they are detoxing when actually it’s defeating the purpose that niacin serves to pass a drug test.

    Hello. I am a 30 year old woman, I weigh 175 pounds, and I am 5’5. I was smoking 1 joint everyday for about 4 months, maybe more on someday. I suspect I may have to test soon, maybe as soon as tomorrow. I have been drinking lots of water the past 2 days (6 bottles- 16.9 oz.) and using sonne’s 7 since yesterday. 1 tbsp. In the am and 1 tbsp. In the pm. What do you think about that? Or have any advice for me? Thank you for your page, it has helped me a lot.

  • T says:

    Drink water till your going to puke or piss yourself and hit the sauna til you can’t no more while drinking water. soon you won’t have to pee anymore you’ll sweat it all out. Take a break drink water repeat. Smoked a couple hits Mon – fri. Killed myself in the sauna over and over sat passed a home test Sunday morning and relaxed. Passed a lab and instant test Monday morning. No sauna? Not recommended maybe a little dangerous but turn your shower full on hot put a garbage bag over your head and sweat your dick off. Took my home test Sunday morning when I woke up because that’s when all the toxins are in your system. Like I said smoked 1 to 3 hits every night Mon to Friday passed monday

  • jj says:

    okay someone answer quick please! i am getting a physical (urine & blood tests) on November 10th. the last time i smoked was from an O pen on october 28. i occasionally smoke every few months or so but for the past month ive been smoking at 1-2 times a week. question 1. will they even be looking for drugs at my check up physical, & question 2. if i stay sober until november 10th and continue drinking tons of water and exercise some, will it be out of my system by then? i am petite 5’0 and no more than 115 llbs. yes i know everyone’s different but please give me an answer, thanks!

  • Poopship says:

    Thanks for the well written article. I have heard one idea that you didn’t touch on much… fiber.

    Apparently the THC metabolites mostly leave your body through stool, the same as cholesterol. High fiber diet leading up to and even a large fiber dose a few hours before can help to move the THC from your blood/urine and into your stool.

    The below link is not the one I was really looking for but it’s the same info.

    Dear Mary Jane..
    Background for US Older, “Old Farts”..
    I’m 54, 5’9″ , unfortunately; due to Health/blood problems”, I’ve Gained some50 pounds over the past year.. Now Weigh 225, AND I cannot see “Muh Junk” now.. 🙁
    A few years back.. I was going to UNC-ChapleHill for, you guessed it, Pain Management..
    Which NOW, with Policies enacted, (before Trump) requires a “drug/pee test”..
    On the Opioid “crisis”.. but I digress..
    On the Morning to UNC, I used a “diluting” agent, called Ultimate Gold.. I’m/was a DAILY smoker since I was 15 years old.. Though before that Morning, I abstained about 10, (TEN) days before my “test”.. Drank plenty of coffee & on the way to UNC-CH, (2 hour drive), (NO water), provided a urine sample, the test which came out… Negative or inconclusive!!!…
    Now mind you, the “Ultimate Gold” I used then,(2015?) tasted like a Cat & dogs arse combined…

    Fast forward to today.. I used the SAME “diluting” agent… (It didn’t taste the same like Cats & Dogs ares’s), though I used it as directed… 2 hours before my Drug screen, with Coffee & Lots of water… 4++ urinations & using a “mid-stream” while being tested..
    Showed “Muh Junk” to the female Nurse, so as to let Her know I wasn’t trying to “sub” My Urine with a bottle/Wissinator.. (folks have been “caught” doing so there)..
    As I said, I’m NOT a “Daily User” though I partook ONLY 2 grams (between Me & Wife), in the past 2 months, sprerad out over the *weeks*….
    Maybe a toke or 2,, 2 days before the test..
    I pissed somewhat clear, though it was MINE, as the Nurse saw, so NO problem there..
    Though I’ll Let Folks know of My “results” in a month..
    I couldn’t afford the “strips” for a “pre-test”..
    Either I can still & keep My pain meds & Doctor,, Or I’ll be cut-off..
    I know folks talk a lot about, Med MJ a lot and whatnot, though at times My pain Levels excede what MJ can or could do..
    Meanwhile Papaver Somniferum seeds are at the ready to be planted..
    Thanks MaryJane on the “stright Talk” on this subject!
    WILL let ya’ll know how it turns out!
    Bandit from SENC..
    Do yourself a favor,, take a KID Fishing, you’ll be glad you did!

  • Emi says:

    Hey, so I’m in military and I’m just had surgery and I have 14 days of convelence leave so when I get back I might get drug tested but I want to smoke a blunt on my first day of leave to help with the pain and then detox. I can’t move around alot because it was an abdomen surgery but I want to do the diluted method. My question is if I smoke Feb 9th will I be clean by Feb 23? Using dilution method?
    Thank you
    Also great article helped alot!

  • J.R. says:

    Hey there, I thought I share my story, maybe it will help someone pass a test and get a job.

    I’m 6’2″ about 150-160 lbs I have a high metabolism.

    Went to an interview for a place that I thought didnt drug test. Turns out they did. I had smoked a joint the night before, and another joint the morning of my test, I took my urine test about 5-7 hours after I smoked in the morning.

    I took the Purity Labs U.S.B. body supplement, I followed the directions, Drank as much water as a could, even more than directed.

    I passed my test (at a clinic/lab) and got the job. Obviously I don’t recommend smoking anywhere near the time of your test but I thought I share my case to show that it is possible and these detox products can help you test clean.

  • Alaina J. says:

    I had stopped smoking in January, I was pregnant, I went into pre-term labor on march 25. the 26th up until april 9 @1:30am I was smoking every day. sometimes not every day but I did. I smoked barely half a blunt this whole month. ive been taking 500mg of niacin 2 times a day. and drinking water and Gatorade and sometimes coffee for the past week. how much longer till I can pass a drug test so I can get my life back together?

    • Bob says:

      Unfortunately depending on your bodies metabolism it could take over 100 days!!!! But if you follow my 7 step method before your test you’ll be fine.. especially if you haven’t smoked in a couple weeks.. check the next post 🙂

  • Bob says:

    This article is great!!!! I just wish I’d found it years ago… Its very close to the method I’ve developed and pieced together from years of research and first hand experience.. here is my 7 step method.. very similar to the article… just boiled down..

    I pissed clean after only 10 days and I’m a heavy heavy heavy smoker and am overweight at 260lbs….

    1. Quit smoking ….obviously, lol
    2. For as long as possible, eat lean (no fat) foods and workout like crazy!!!
    3. During this time take Niacin tablets and Cranberry extract pills
    4. Three days before test start eating as much fatty foods as possible
    5. Two days before test, take Creatine supplements and Vitamin B pills
    6. Day of test, drink lots of water, PISS BEFORE YOU GO
    7. At the test, give them only mid stream piss, not beginning of stream

    So the Niacin and Cranberry will clean out your system a bit… eating shit tons of fatty food after being on a diet will rebound your weight and you’ll put on a layer of “clean” fat to hide the tainted.. lots of water will dilute your sample but if its too dilute they will reject it.. so the creatine brings the specific gravity back up to normal and the vit b will keep your pee yellow even after its diluted.. obviously the first piss of the morning is most concentrated,, as is the very first bit of every piss.. don’t give them this…obviously doing step 1 for as long as possible is the best way to improve your chances.. but this system should work for anyone.

  • Hi therе, I enjoy rеading all of your post.
    I like to write a little cοmment to support you.

  • BlueDreams says:

    Been smoking for over 20 years. However, I did stop smoking for 5 days for a pre-employment drug test. Day of my test: 3.5 hours prior i drank 24oz of cranberry juice w/certo and 24oz of water; plus 1.5 hours prior i drank a detox drink called xxtraclean waited 15 min refilled water and pissed 4 times and went # 2 (TMI I know) lol. It’s been 2 days since my test and waiting on if I passed to get the job of my dreams. Do you think I have chance of passing? (: really nervous >.<

  • Paul says:

    I’m a male 5’8” 200 lbs average metabolism. I’d say I’m a little heavy but not fat. I had to try some of these methods since I’ve been in parole for 14 years and I smoke weed maybe one month a year but when I do it’s like 2 to 3 grams a day of loud. I tried the Palo Azul tea I tried the niacin the Certo the golden seal root many many detox drinks. i found that of all the things that people do to pass for there is only three methods that work. Fake piss. Visine drops into the cup and it’s clean for thc. Those two methods work but for me in my case just too risky to do on a regular but I have a few times subbed and added the Visine a couple times to my cup and then pissing with the dirty piss. The number one way for supervised UA is dilution. My case they don’t lab it it’s all done on the spot in a cup with lines. I don’t do any other drugs but I do drink. Dilution works for ETG screens as well. Look up N2 dilution method. I promise you all those three are all that will work. Do not believe the bullshit. If Palo Azul has worked for others it’s simply because the gallon of tea diluted the urine enough to pass. I’ve tried it several different brands and methods so that one is bunk. Dilution is best for observed believe me but you have to stop smoking at least a week before and exercise like crazy in that time then do it and you’ll pass for any drug. But you have to have that week or so of sobriety or your screwed. Now if your talking about an unsupervised visit and need to pass then there is only one obvious option. Subbing. Temp isn’t and issue. Microwave it for 10 seconds or so then put it in your underwear with a hand warmer. Be sure buy the urine with the temp strip. If it’s too hot when you get in the restroom dip the closed urine bottle into the toilet water a few times to cool it off. The two times I used this it worked perfect. I also have a buddy used this upon my recommendation for work and it’s a GS job and lab and all and he did the exact same thing and was good to go at least 4 times. So there you go. N2 dilution method and subbing best two options.

    I am 35 years old 4ft 8in 117lbs I go Wednesday next week to apply for a job my brother-in-law told me I would be drug tested for Marijuana and other drug’s. I was wondering how to clean my system in 3 day’s?

  • Jane says:

    I haven’t smoked since Jan 5th I have a drug test feb 6th I’ve been drinking water and on my second bottle of Sonne 7..and I’m still not passing my at home drug test! Any advice I smoked every night.

  • Pissed positive says:

    I wa stoking pretty hard and often, mostly through a vape pen. I was also eating wrinkles for a few weeks. I stopped it all on January 1st, I took an over the counter test yesterday that claims 99% accuracy and failed. My test is tomorrow so as you could imaging I am shitty my pants. I’m going to pick up some strips and try the dilution method today and pray. It’s been almost 40 days, I can’t believe I would test positive. Wish myself luck.

  • Worried in Cali says:

    Would really really really appreciate any input..I have a drug test coming up soon probably within the next 7 days. I have not smoked for 21 days. Before I was using my vape pen every night 7-8 puffs a night for about a month. Prior to that I would smoke off and on. I’m 5’8 and about 185-190 pounds. I did a detox or cleansing a little over a week ago and took a at home test the day after the cleanse with negative results. Since then I have not been consuming as much water or eating as healthy as I was while doing the cleanse. Today, about a week after my first at home test, I decided to test myself again and I believe it came back positive. As the line was very very faint. My boyfriend swears he saw a line but clearly I need to get another test to make sure. Replacement is not an option. I’ve read the comments but I’m still not sure what I can be doing to help make sure I pass my next at home test and ultimately my drug test. I can’t fail! I got into a program I’ve been working towards this moment for two years. I was told about a month ago I didn’t get in-which prompted me to smoke again. But then a month later I found out I did get in! Wish I never smoked again. Please help!

  • Jade says:

    If I faintly passed a 20 ng test with my first pee when will I pass a 15 ng test in case of a random? Any suggestions?

  • These comments are silly says:

    Thanks for the info. Im trying a combination of niacin and and palo azul for the next few days. May or may not return with an update cause it might be a while till I know if I passed. But this page has been quite helpful.

    Hope your doing well out there in the world Mary Jane, peace
