In which decade did the first LSD trip occur, according to the material's timeline?

• A. 1900s
• B. 1920s
• C. 1940s
• D. 1960s

Answer: (C)

Understanding this question means centering on LSD’s historical timeline. Although LSD was first synthesized in 1938, the first deliberate psychedelic experience occurred in 1943, when Hofmann ingested the substance and had a profound trip (often recalled as Bicycle Day). That places the first LSD trip in the 1940s. The 1900s and 1920s are too early for any LSD experience, and the 1960s reflects when LSD became popular culturally, not when the first trip happened. So the 1940s is the correct decade.
