Hallucinogens, especially LSD, were prominent in the hippie culture of the 1960s and 1970s, but their popularity declined during the 1980s, giving rise to harder substances such as cocaine. In 1972 it was reported that five percent of the nation, primarily under the age of eighteen, had experimented at least once with LSD. In 1974 that number had leapt to seventeen percent, and by 1979 the numbers were up to twenty-five percent. These numbers dropped steadily as heroine and cocaine gained popularity in the

Hofmann relayed his experience to his superiors, who at first doubted his account, but upon their replication of his experiment all doubts were eliminated.

Albert Hofmann, a chemist working at the Sandoz Corporation pharmaceutical laboratory in Switzerland, first synthesized LSD in 1938. Hofmann was researching medical uses of lysergic acid, a derivative or ergot (fungus that develops on rye grass). Hofmann developed many lysergic acid compounds, the one that made him famous though was the 25th called, in German, Lyserg-Säure-Diäthylamid 25, or LSD-25.
