Project MKULTRA was the code name of a covert, illegal operation of the US Central Intelligence Agency that used US and Canadian citizens to research interrogation methods and behavior modification without their knowledge or consent. The full extent of the project is unknown, since the CIA ordered all MKULTRA files destroyed in 1973. The project, which lasted from the 1950s to the late 1960s, included the surreptitious administration of drugs such as LSD. What other experiments were conducted? Discuss
