70 years ago today, Albert Hofmann, PhD. took the worlds first accidental trip on LSD. After synthesizing a batch of LSD-25 he accidentally absorbed some. The following are his notes on the event:
Last Friday, April 16, 1943, I was forced to stop my work in the laboratory in the middle of the afternoon and to go home, as I was seized by a peculiar restlessness associated with a sensation of mild dizziness. On arriving home, I lay down and sank into a kind of drunkenness which was not unpleasant and which was characterized by extreme activity of imagination. As I lay in a dazed condition with my eyes closed (I experienced daylight as disagreeably bright) there surged upon me an uninterrupted stream of fantastic images of extraordinary plasticity and vividness and accompanied by an intense, kaleidoscope-like play of colors. This condition gradually passed off after about two hours.
A couple days later on April 19th, he took his first planned test of LSD and the infamous bike ride took place.
