Yeah, I've always thought of how screwed up it is that LSD is Schedule 1.
I mean, think about it! When Leary conducted his early experiments with it, he gave it to upstanding religious leaders (way back before it was a household name); priests, reverends, baptists, etc. Pretty much universally, they were in agreeance that they had THE MOST RELIGIOUS EXPERIENCE OF THEIR LIVES. Years of training, teaching, preaching, soul healing, and LSD opened their minds to the divine the most. Astounding.
On the flip side, as Ethnobotanist mentioned, the Canadian and U.S. governments (chiefly the C.I.A.) conducted HIGHLY ILLEGAL experiments in testing the viability of acid as a truth serum, a weaponized hallucinogen, etc. They even went so far as to open brothels, and then blackmail the people who went into pretty much signing over their lives and their sanity to the tests.
Project MKULTRA, a C.I.A. project, was a truly sick endeavor. In some cases, they gave unsuspecting people LSD, then put them in a sensory deprivation chamber (they blind you, make it so you can't hear, gag you, then hoist you into the air so any sense of sight, sound, even gravity is taken away from you). In my worst nightmares I cannot picture anything worse.
But hey, whats tax dollars spent without results? After all, they did find a truth serum: dose up a person with a high dose of stimulants, then dose them with a high dose of relaxants/sedatives. Just before they stroke or die, they tell the truth.
God bless America.
