Project MKUltra, also called the CIA's mind control program, is the code name given to a program of experiments on human subjects, at times illegal, designed and undertaken by the United States Central Intelligence Agency.[1] Experiments on humans were intended to identify and develop drugs and procedures to be used in interrogations and torture, in order to weaken the individual to force confessions through mind control.
