So far as I've heard there is no way to test for Psylocibin with the exception of a blood toxicity screen via a blood test. Is this true? or is this just something stupid that I heard from a friend of a friend? By the way, this is purely out of curiosity, I haven't had any reason to take a drug test for almost 2 years now and I am not trying to find a loophole to any system, just curious about the drug itself and the possibilities to detect it.
