Can You Donate Blood If You Smoke Weed?

donate blood weedDonating blood saves lives, and I highly recommend it. For weed smokers, anytime someone wants a sample of your blood it can be kind of nerve wrecking. So, the question is: do blood drives test your blood for THC? Can you get in trouble for trying to donate ‘tainted’ blood? 

The Short Answer

I’ve contacted several blood donation companies and here is the general consensus: It’s totally cool for weed smokers to donate. Blood centers do not test for THC in your blood; however, they may turn you down if you are visibly high at the time you arrive to give blood. 

So weed smokers can give blood without any worries (just lay off it before going in.) This sounds pretty reasonable to me.

Here’s the Email I wrote:

Hello,
I’m writing an article, and wanted to get some information. Do you test blood for THC? If so, does the presence of THC make someone ineligible to give blood?

Thanks

American Red Cross:

The American Red Cross Responded very quickly with the following: 

Thank you for contacting the American Red Cross. We appreciate your time and willingness to keep our blood supply at a safe level by wanting to donate at one of our collection sites. In regards to your question and the information you provided and by looking at our guidance I have determined that this will not prevent you from donating blood. As long as you are not under the influence at the time of donation, the presence of THC will not prevent you from donating.

Thank you so much for your willingness to donate. If you have any other questions or concerns please feel free to contact us by replying back to this email or by calling 1-866-236-3276. Have a great day and once again thank you for taking the time to contact us.

America’s Blood Centers:

America’s Blood Centers was a pain to get in contact with. I sent them several emails with no response. Finally, I looked up a center within their network and got a super speedy response from Bonfils Blood Center in Denver. 

The purpose of testing donated blood is to detect infectious diseases that are transmissible by transfusion. Donated blood is not tested for THC.

Bonfils Blood Center, as is the case with many other blood centers across the industry, does not defer donors for marijuana use unless the donor is visibly impaired or has another condition for which he/she is using medical marijuana such as cancer which would preclude him/her from donation.

Please let me know if you have any further questions.


So there you have it folks. You may donate blood without fear or tyranny. Got a story about giving blood? Tell me about it in the comment section below.

    I am a regular Marijuana user and have been donating regularly for years. I never go when feeling high(my appointment is usually early). In fact, I usually will take 1 extra juice and fruit gummie for munchies later.

    Just remember to drink as close to a gallon of water as you can within 24 hours of donating. It will make the process faster, easier, and overall more enjoyable.

    Also, eat the sugary snacks and juices they provide. You just got blood taken from you, your blood sugar is going to be low. If you do anything that could be strenuous with low blood sugar you will most likely pass out or feel SUPER weak so eat the yummy snacks and juice!

        I knew I was going to donate today so I didn’t smoke for a couple of days, I am hypoglycemic so knowing this I always chug oj and chocolate chip cookies before and eat the snacks after. Today was no different before, but after they gave me one 100 calorie snack pack and a bottle of water. My mind was totally blown when I asked why that was it, weren’t they worried about ppls blood sugar? They said people only need a little sugar to be fine and it keeps them from overeating and gaining weight. By the time I got off (I work at a miserably hot manufacturing plant), I could barely walk and was trembling horribly. Needless to say I will not be donating through them anymore!

    Im a Freshman in college and began smoking regularly this year. I began smoking at the beginning of the school term and was asked if I wanted to donate blood. Not even thinking I agreed to it. Mind you I’ve always donated at blood drive s. With six under my belt I had become a regular donor. However when I got to the blood drive it all hit me and I decided to ask if I could donate blood if I smoked. The last time I had smoked was two days before and I informed the worker of this. He looked me dead in the eyes and said “Yeah of course you can donate kid. I’m a huge pothead. Probably going to smoke after we shutdown here.” I was super relieved. It was cool to know that I can be high AND save lives.
