Once practically everything a person did was subject to Machiavellian limitations and description. Not only were you burned at the stake for your beliefs, but you couldn’t say much about just about anything–or assemble for any reason.
In all the psychedelic literature it is the scientists that have focused on the chemicals themselves, and apart from the indigenous cosmovisions that ascribe a relationship with the spirits in the plants (as with madre ayahuasca in Peru, for example), there has been little Western appreciation of the reason that nature produces these substances in significant amounts across uncounted vegetal carriers.
The Supreme Court has never ever examined the Constitutionality of outlawing anything like that, which is personal behaviour. Drugs can’t be controlled in any way by making them illegal.
