MK-ULTRA

Project MKUltra began in 1953 and was halted in 1973. MKUltra used numerous methods to manipulate its subjects' mental states and brain functions, such as the covert administration of high doses of psychoactive drugs (especially LSD) and other chemicals without the subjects' consent. Additionally, other methods beyond chemical compounds were used, including electroshocks, hypnosis, sensory deprivation, isolation, verbal and sexual abuse, and other forms of torture.

Project MKUltra was preceded by Project Artichoke. It was organized through the CIA's Office of Scientific Intelligence and coordinated with the United States Army Biological Warfare Laboratories. The program engaged in illegal activities, including the use of U.S. and Canadian citizens as unwitting test subjects.

American historian Stephen Kinzer said that MKUltra was

a continuation of work that began in Japanese and Nazi concentration camps. Not only was it roughly based on those experiments, but the CIA actually hired the vivisectionists and the torturers who had worked in Japan and in Nazi concentration camps to come and explain what they had found out so that we could build on their research.
