Project MKUltra

Project MKUltra began in 1953 and was halted in 1972. 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.
