Bicycle Day commemorates April 19, 1943, when Swiss chemist Albert Hofmann intentionally ingested LSD, a substance he had synthesized, and experienced its profound effects during a bicycle ride home from his laboratory. This event marked the first intentional LSD trip in history and played a pivotal role in the discovery and subsequent research into psychedelics.

To this day, Bicycle Day is celebrated by enthusiasts of psychedelic culture as a day to reflect on the potential of these substances for personal growth, creativity, and therapeutic purposes. It also serves as a reminder of the importance of responsible use and scientific exploration in understanding altered states of consciousness.
