The Accidental Trip That Changed Everything

In 1943, Swiss chemist Albert Hoffman absorbed a tiny amount of a compound he had synthesized five years earlier and set aside. Soon after, he found himself in what he later described as "a dreamlike state, with eyes closed, perceiving an uninterrupted stream of fantastic pictures, extraordinary shapes with intense kaleidoscopic play of colors." This was the first LSD trip in history—entirely unintentional. Hoffman took what he thought was a small dose of 250 micrograms (it was actually substantial) and barely managed to cycle home, where furniture appeared "grotesque and threatening" and he feared he might be dying. But as the drug wore off, he experienced an afterglow: the world outside his garden seemed to sparkle. That single accidental exposure launched a substance that would shape psychiatry, counterculture, government mind-control experiments, and global drug policy for decades to come.
