I have been asked before if I use illict drugs, most blood wagons will do a pre interview that is confidential.. they will even take your blood so yu can save face, then they will not use it.

Actually, most places will need 2 blood samples. Also with plasma. They test the first "batch" for infections and drug use. Only after the blood is clean enough to want to pump into another human being will they use the second batch...

No, they test you right there with an onsite tester and if your bloods dirty you can't donate. You're also put on a list that is circulated to all the blood banks to not take your blood. This includes the pay places. Jsut don't waste their time and resources fo rblood they can't use.

Sure, why not. I truly doubt they test for that stuff.

From the Savannah Red Cross Website on the what conditions are exceptable for blood donaton:


Marijuana, "Weed", "Pot", "Ganga"
Acceptable as long as you are not under the influence of marijuana at the time of donation.

Don't believe it? Check it out for yourselves, everything you've ever wanted to know about giving blood:

One more thing, as someone who volunteers regularily at a hospital AND donates blood, I would just like to say that it is highly irresponsible for unqualified people to advice others NOT to give blood. I know where I live, we are at a critical shortage right now. Medical professionals specifically say that it is okay to donate if you smoke marijuana, as long as you are not high at the time. If you are willing to give your blood to save another's life, then bless you and thank you.

I give blood about 3 or 4 times a year depending on when they are doing the drives, and where I am, and I am here to tell you I am an avid smoker, and they have never denied me for it. True i don't smoke like 20 minutes before I go, but even a few days would show up in some sort of test.
Don't be nervous that they are going to have police men arrest you or something.. You have to wait a year if you've had piercings or tattoos.

Wow, there seem to be a lot of myths out there as to what accually happens to blood once it is donated. I got this off the Red Cross website. It says nothing about specificaly testing for marijuana, so I doubt they do. Hope this helps.

What Happens to Every Blood Donation?
While the blood supply is safer than ever, the Red Cross has continued to make important advances in testing and processing.
Assuring the safety of the blood supply is a high-tech process requiring at least nine specific tests; proper processing, labeling, and storage; and vigilant quality control.

Routine donations are now tested for HIV and hepatitis C through nucleic acid testing (NAT), an investigational test that may reduce the "window period" — the time between a virus infecting the blood and the body forming antibodies that can be detected.

The Red Cross has also made progress in providing a universally leukoreduced blood supply (removal of contaminated white cells), with virtually all blood provided as leukoreduced products in 2001. This is important because leukocytes (white blood cells) may not be tolerated well when transfused with red blood cells.

Sure, MJ has no affect upon the blood you give.
It shows up as a residual trace and that's how they can tell if you smoked it in your urinalysis. It has zero impact on the quality of the blood you donate.

Marijuana and its metabolites aren't found in the blood after more than a week, so if you abstain there's no reason you can't donate blood. Other drugs have varying times they can be tested for in blood tests. If you have ever, even once, used IV drugs, then you should admit to it. They will screen it thouroughly anyway, and toss it if there's anything wrong.

People with tattoos and piercings can donate blood as long as the procedure was done with sterile materials, in most countries.

They don't care about marijuana. They are far more concerned about use of intraveinous drugs, unprotected or high-risk sexual activity, and other factors that could potentially put you at risk for having "tainted" blood such as tattoos and hepatitis.
