Between 1955 and 1963, federal agents ran a hidden brothel in one of San Francisco's poshest neighborhoods and tested LSD on unsuspecting Bay Area residents. The apartment building is still there, although it has been converted from a CIA brothel into a four-story mansion. At the center of this wildly unethical program was George Hunter White ... who became one of the biggest crusaders of America's early war on drugs. In public, he railed against drug use and ruthlessly investigated jazz legends like Billie Holiday. Privately, however, he drank martinis by the pitcher and even used drugs like LSD and marijuana. White was the federal agent responsible for a top-secret CIA program called Operation Midnight Climax." The CIA thought it could use hallucinogenic drugs like LSD as weapons of war against its enemies. To find out, the agency got Bay Area residents high without their consent. White outfitted rooms inside a Telegraph Hill apartment building, at 225 Chestnut St., into a safe house for testing LSD. He gave sex workers get-out-of-jail-free cards in exchange for luring unsuspecting johns to the apartment, where the men were dosed with acid while White watched from the other side of a one-way mirror. According to a letter unearthed by John Marks in his 1979 book "The Search for the 'Manchurian Candidate,'" it was nothing but "fun, fun, fun." "Where else could a red-blooded American boy lie, kill, cheat, steal, rape, and pillage with the sanction and blessing of the All-Highest?" White asked.
