The group mind has been a theme in psychedelia all the way back to the Merry Pranksters in the 1960s. Indigenous cultures often take medicine to journey together not just to heal–but to vision, explore and create.
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. You want people to not use drugs? Well it seems pretty silly to make selling drugs the most lucrative job you can get.
According to Martin A. Lee and Bruce Shlain, authors of Acid Dreams: The Complete Social History of LSD: The CIA, The Sixties, and Beyond, there was over a decade of legal and illegal testing of LSD by the CIA on it’s own men, from 1953-1966, when they dosed unsuspecting doctors and servicemen to see if the chemical would make an efficient brainwashing mechanism.
