Donating blood at school

[hello3pat]

I was planning on donating blood at my schools blood drive on monday but I relized that during the blood screening process they might check for THC. Does anyone know if they do? If so, the last I smoked was 3 weeks ago, would I be clean?

No, they will not test for THC. Also, 3 weeks you will be fine.

they wont find anything after 3 weeks and youll get free cookies!
