Can people who smoke marijuana give blood?

Answer by  rightlight (1053)

People who smoke marijuana can donate blood and plasma. This is because THC is not stored in the bloodstream, but rather it reacts with cells in the brain and is stored in fat and hair cells throughout the body. It is not recommended you smoke right before a donation however.

While I am sure the agency collecting the blood would prefer that you not smoke, using marijuana shouldn't impede your ability to donate blood. The THC is stored in the fat cells, so as long as you weren't using the day of the donation, there shouldn't be any present. If you want to be safe, stop smoking thirty days before.
