Bicycle Day commemorating April 19, 1943, when Dr. Albert Hofmann first took LSD intentionally. Three days earlier, he had absorbed a small amount of the drug either through his fingertips or by accidentally ingesting it. On Bicycle Day, he took 250 µg of LSD intentionally and, fearing he had made himself ill, cycled home from his lab. During his bicycle ride, he experienced the effects of LSD, making this the date of the first ever acid trip.
