Albert Hofmann's Trip

Brian Blomerth’s Bicycle Day, published by Anthology Editions, documents events on 19 April 1943, when Swiss scientist Albert Hofmann embarked on the world’s first acid trip.

He described what he felt as being:... affected by a remarkable restlessness, combined with a slight dizziness. At home I lay down and sank into a not unpleasant intoxicated[-]like condition, characterized by an extremely stimulated imagination. In a dreamlike state, with eyes closed (I found the daylight to be unpleasantly glaring), I perceived an uninterrupted stream of fantastic pictures, extraordinary shapes with intense, kaleidoscopic play of colors. After some two hours this condition faded away

Three days later, on 19 April 1943, Hofmann intentionally ingested 250 micrograms of LSD. This day is now known as "Bicycle Day", because he began to feel the effects of the drug as he rode home on a bike. This was the first intentional LSD trip.

Hofmann continued to take small doses of LSD throughout much of his life, and always hoped to find a use for it. In his memoir, he emphasized it as a "sacred drug": "I see the true importance of LSD in the possibility of providing material aid to meditation aimed at the mystical experience of a deeper, comprehensive reality."  (Wikipedia)
