Questions People Usually Ask:

Q: Does the Red Cross tell people who use marijuana not to give blood?

A: No. The Red Cross wants all healthy people who are eligible to give blood to make an appointment by using the Red Cross Blood Donor App, going to, or calling 1-800-RED CROSS.

Do I have to wait to give donate a blood if I’ve used cannabis? If so, why?

A: There is no information about how long someone should wait after using cannabis before giving blood. Please don’t come to donate if your cannabis use is making it hard for you to remember or understand things.

Q: Doesn’t the Red Cross have to follow rules set by the Drug Enforcement Administration, the same group that says cannabis is a Schedule One drug?

A: The U.S. Food and Drug Administration, not the U.S. Drug Enforcement Administration, decides who can give blood. Blood collectors are not required by the FDA to test for THC.

Q: Does the Red Cross ever look for THC in blood samples?

A: No.

Q: What if I use products with a lot of THC, like waxes or dabs? Does that make me ineligible?

A: No. Again, we ask that you don’t come to donate if your cannabis use is making it hard for you to remember or understand things.

Q: I’m a heavy cannabis consumer. Can a transfusion recipient fail a drug test if they receive my blood?

A: No.

Q: Can I donate blood to the Red Cross if I take prescribed synthetic marijuana (the FDA uses the term “synthetic cannabinoids”) or recreational varieties like K2 and Spice?

A: The FDA does not have universal guidelines regarding synthetic marijuana (a.k.a “synthetic cannabinoid”) and leaves decisions about the acceptability of donations from these users up to local blood centers. This is because they are in the best position to know if disqualifying contaminants have been turning up in their areas.

Whether the synthetic marijuana you take is a prescribed medication or a recreational variety, our best advice is to contact our Red Cross Donor and Client Support Center at 1-866-236-3276.

Q: Do different guidelines apply to cannabis or synthetic marijuana consumers who want to donate platelets or plasma specifically?

A: For a cannabis user donating platelets or plasma, the guidelines are the same as they are for donating whole blood.

For synthetic marijuana users, there are concerns that some varieties of non-prescription synthetic marijuana have been found to contain certain anticoagulants known to contaminate plasma.

Policies about accepting whole blood, platelets or plasma donations from recreational synthetic marijuana consumers are currently set by each local blood center. Those policies vary depending on whether or not contaminants have been turning up in their areas.

If you are a recreational synthetic marijuana consumer who wants to donate plasma, we strongly suggest you contact our Red Cross Donor and Client Support Center at 1-866-236-3276.
