How to Change Your Mind: The New Science of Psychedelics

by Michael Pollan

until one April day in 1943, in the middle of the war, when Hofmann had “a peculiar presentiment” that LSD-25 deserved a second look. Here his account takes a slightly mystical turn. Normally, when a compound showing no promise was discarded, he explained, it was discarded for good. But Hofmann “liked the chemical structure of the LSD molecule,” and something about it told him that “this substance could possess properties other than those established in the first investigations.” Another mysterious anomaly occurred when he synthesized LSD-25 for the second time. Despite the meticulous precautions he always took when working with a substance as toxic as ergot, Hofmann must somehow have absorbed a bit of the chemical through his skin, because he “was interrupted in my work by unusual sensations.” Hofmann went home, lay down on a couch, and “in a dreamlike state, with eyes closed … I perceived an uninterrupted stream of fantastic pictures, extraordinary shapes with intense, kaleidoscopic play of colors.” Thus unfolds the world’s first LSD trip, in neutral Switzerland during the darkest days of World War II. It is also the only LSD trip ever taken that was entirely innocent of expectation.
