Yes.
r u admitting to smoking marjiauna? naughty nuaghty..jk i dont know
i looked into that, i'm a fricken super duper pothead, and i wanted to donate blood. yes its safe.
You know, I've never thought about it, but, it's not one of the questions they ask you to make sure that your blood is okay. THC stays in the fatty tissues, which is one of the reasons hair and urine tests detect the use of pot.
Probably you shouldn't though, because... THC is a foreign substance that shouldn't get transferred to someone who has lost blood (and needs a transfusion)
now in my opinion, if your gonna donate blood thats wonderful, but if your gonna smoke weed, which is no problem in my book,then maybe its time to decide which is more important to you, but as far as the medical do's and dont's, I would have to say its not recommended, especially if your on probation.might make your probation officer alittle ticked.lol
