1943 –Albert Hofmann deliberately doses himself with LSD for the first time, three days after having discovered its effects on April 16.
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. (wikipedia)
It gave me an inner joy, an open mindedness, a gratefulness, open eyes and an internal sensitivity for the miracles of creation…. I think that in human evolution it has never been as necessary to have this substance LSD. It is just a tool to turn us into what we are supposed to be.
