**Happy Bicycle Day On April 19, 1943, Albert Hofmann, the Swiss father of psychedelic medicine, dropped lysergic acid diethylamide (LSD) and went on a bike ride, becoming the first human to ever trip on acid. The rest is psychedelic history. Hofmann had synthesized LSD in his lab as a medical stimulant for the respiratory and circulatory system in 1938. Revisiting his discovery five years later, he caught a glimpse of its effects when some of the drug was absorbed through his fingertips, describing the experience as “dream-like” and a “not unpleasant intoxicated-like condition.” Intrigued, three days later — on a day that would go down in history as “Bicycle Day” — he did what any responsible scientist would do: Experiment on himself. Taking a dose of 250 micrograms in his laboratory, Hofmann turned on, tuned in, and dropped out for the first time. Within an hour, his perception began to ebb and flow rapidly, and he began to freak out. Hofmann wanted to go home. Hofmann made the journey home by bicycle. In his notes, he went on to describe the hallucinogenic trip: “Now, little by little I could begin to enjoy the unprecedented colors and plays of shapes that persisted behind my closed eyes. Kaleidoscopic, fantastic images surged in on me, alternating, variegated, opening and then closing themselves in circles and spirals, exploding in colored fountains, rearranging and hybridizing themselves in constant flux.” The historical event was, quite literally, a bike ‘trip’ taken by Dr. Albert Hofmann.
