Agreed, but in a slightly different context: The mixture of psychedelics and many prescribed pharmaceuticals is a danger not many know about, particularly SSRI's. Due to this lack of information the dangers of a bad reaction --psychological or physiological-- are very real; in the case of such, it's always the illegal drug that is blamed, regardless of it's actual toxicity. In the case of Psilocybin or LSD or even DMT (the "nuclear bomb" of psychedelics) actual, measurable neurotoxicity is negligible if non-existant. (That being said, one can never be sure what one gets from the street, but in a controlled laboratory setting this is certainly the case.)
