Project MKUltra – sometimes referred to as 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. 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. Organized through the Scientific Intelligence Division of the CIA, the project coordinated with the Special Operations Division of the U.S. Army's Chemical Corps.
The operation began in the early 1950s, was officially sanctioned in 1953, was reduced in scope in 1964, further curtailed in 1967, and officially halted in 1973. The program engaged in many illegal activities, including the use of unwitting U.S. and Canadian citizens as its test subjects, which led to controversy regarding its legitimacy. MKUltra used numerous methodologies to manipulate people's mental states and alter brain functions, including the surreptitious administration of drugs (especially LSD) and other chemicals, hypnosis,sensory deprivation, isolation and verbal abuse, as well as other forms of psychological torture.
The scope of Project MKUltra was broad, with research undertaken at 80 institutions, including 44 colleges and universities, as well as hospitals, prisons, and pharmaceutical companies. The CIA operated through these institutions using front organizations, although sometimes top officials at these institutions were aware of the CIA's involvement. As the US Supreme Court later noted in CIA v. Sims 471 U.S. 159 (1985) MKULTRA was:
concerned with "the research and development of chemical, biological, and radiological materials capable of employment in clandestine operations to control human behavior." The program consisted of some 149 subprojects which the Agency contracted out to various universities, research foundations, and similar institutions. At least 80 institutions and 185 private researchers participated. Because the Agency funded MKUltra indirectly, many of the participating individuals were unaware that they were dealing with the Agency.
