Albert Hofmann, a research chemist at the Sandoz Laboratories (now Novartis Pharmaceuticals) in Basel, Switzerland, left work due to "a remarkable restlessness" and "dizziness." Later, he experienced a "stream of fantastic pictures, extraordinary shapes" and "intense...colors." Dermal absorption of LSD-25, a substance he was working with, was the suspected cause. Although unintentional, this was the first LSD-induced psychedelic experience. Three days later, Hofmann confirmed his suspicions by ingesting 250 micrograms of LSD, about 10 times the threshold amount.
