To drop acid means to take LSD — the classic psychedelic drug. 'Drop' refers to swallowing a tab (a small piece of blotter paper soaked in the substance), and 'acid' has been street slang for LSD since the 1960s counterculture. The phrase is deeply woven into the history of psychedelic culture, from Woodstock to Haight-Ashbury to modern festival scenes. It's widely understood slang that shows up in music, film, and literature as shorthand for a psychedelic trip.
