I'm reading that LSD is safer than caffeine. Good too know. I've never done the stuff, or anything else on the graph other than alcohol, but it's good to know that LSD is so safe.
I doubt that LSD is all that safe in practice. Nor that caffeine is particularly dangerous.
There's a new documentary on Netflix called "Wormwood" about early CIA experiments with LSD. Apparently they gave some poor guy LSD without his knowledge and he ended up either falling or jumping out of a window. I did try it a couple times in my youth and I wouldn't do it again. The effects last at least half a day. If you have a "bad trip" it's going to last probably 10 or 12 hours. I remember it made my spine hurt among the other effects. It wasn't a pleasant experience, but I got through it. https://en.wikipedia.org/wiki/Frank_Olson
Frank Rudolph Olson (July 17, 1910 – November 28, 1953) was an American bacteriologist, biological warfare scientist, and Central Intelligence Agency (CIA) employee who worked at Camp Detrick (now Fort Detrick) in Maryland. At a meeting in rural Maryland, he was covertly dosed with LSD by his CIA supervisor and, nine days later, plunged to his death from the window of a 13th-story New York City hotel room. The U.S. government first described his death as a suicide, and then as misadventure, while others allege murder. The Rockefeller Commission report on the CIA in 1975 acknowledged their having conducted drug studies.
Olson asked to quit the biowarfare program the week after the retreat:
Ruwet was surprised to see Olson at 7:30 in the morning, but asked him in. Olson told Ruwet that he was dissatisfied with his own performance at the retreat, that he was experiencing considerable self-doubts, and that in fact he had decided he would like to be out of the germ warfare business. He wanted to leave Camp Detrick and devote his life to something else.
Olson subsequently suffered severe paranoia and a nervous breakdown. The CIA sent him to New York City to see one of their physicians, who recommended that Olson be placed into a mental institution for recovery. This was Harold Abramson, an allergist-pediatrician, who was helping the CIA with the psychotropic research into the effects of the drug.
The ensuing police report said that on his last night in Manhattan, Olson purposely threw himself out of the window of his tenth-floor hotel room at the Hotel Statler, which he had been sharing with Lashbrook, and died shortly after impact.
A fool thinks himself to be wise, but a wise man knows himself to be a fool.
