Desperate/suffering/destitute drug addicts are addicted to drugs. Psychedelic/psychotropic drugs, tryptamines in particular (i.e., the subject of the discussion), are not physically addictive. Obviously, "responsibility" and "moderation" are important considerations for ensuring personal safety in the long term, but I have trouble believing that the depravity you discuss has much at all to do with psilocybin and its ilk. These are simply not "drugs of abuse" in the typical sense. Of course, anything can be abused, and those with schizophrenic tendencies may be especially affected by drugs, but marijuana does not necessarily exacerbate these issues. In my experience, marijuana had quite the opposite effect on someone I knew - calming, etc. This is just my experience, and I am no expert on schizophrenia. The point is that anything can be abused, but I don't believe that magic mushrooms have much to do with the drug "epidemic" and its ramifications.
