Can you donate plasma, if you smoke weed?

This blog post is for people who are wondering if they can donate plasma after smoking weed. The answer is yes, but there’s a catch.

If you smoke weed on a regular basis, your body starts to produce more THC-COOH and it stays in your system longer than someone who only smokes occasionally.

This means that when you go to donate plasma, it will show up in the test results as an active drug rather than inactive metabolites of THC-COOH which have been stored in your fat cells from previous use. Before you go to donate plasma, make sure that it has been at least 30 days since your last use.

There are certain centres that have a THC cutoff of 50 ng/ml or more and will not let you donate if the test is positive for marijuana.

If that’s the case with your centre then there isn’t much else you can do other than to wait until after visiting before trying again.

It’s also important to know how long weed stays in your system because when donating blood, the time period varies from person to person depending on the frequency of use and amount consumed each time.
