Some days ago I went to donate blood in my local community center (they do this several times a year). However, when I said I had used MDMA two weeks earlier, they told me they could NOT use my blood.

Does this make any sense to you? It was this really old fashioned looking rectal-exam type head nurse who looked “not amused”, so it could very well be prejudice on her part. Should I simply not mention it next time?


Half-life of MDMA is 6-10 hours. Aproximately in 50 hours there is no rest of substance in your body. That is a reasonable time to donate blood. There are a lot of prejudices to drug users, and the nurse probably did not distinguish between MDMA and injected heroin . There is no pharmacological reason to exclude a person 2 weeks using MDMA.
