I am thinking of donating blood very soon, but i have smoked weed within the past month, am i still able to donate?

Donating blood: When you donate, they'll ask questions about your health, travel, and sexual history to make sure it's safe for you to donate, and for your blood to be in the system. They don't routinely ask questions about marijuana use. But should your blood be tested for this, it could show up positive depending on how frequently and when you use.

Should be : I agree with dr. Pappas. History of IV drug use excludes. You can find a list of eligibility requirements at: http://www.Redcrossblood.Org/donating-blood/eligibility-requirements/eligibility-criteria-topic.
