In 1968, Denver police busted a LSD lab in the basement of a house. Westword reporter Chris Walker tells Colorado Matters this was actually one of two labs run by Tim Scully. His underground drug operation is said to have boosted the global proliferation of psychedelics.

Walker digs into this history in his latest cover story, "Acid Trip: Denver's Secret LSD Labs Fueled the Psychedelic Revolution."
