Washington, December 25 (RHC)-- A memo released by the U.S. National Security Archive revealed that between 1950 and 1960, Central Intelligence Agency (CIA) agents used drugs, mind control and other techniques to conduct interrogations of suspected spies.

The information was exposed on Monday 50 years after The New York Times published the Seymour Hersh investigation ''

The mind control techniques, the memorandum specifies, were developed in the context of the MKULTRA, BLUEBIRD and ARTICHOKE programs and contemplated the "use of drugs, such as the hallucinogen LSD, hypnosis, isolation and sensory deprivation (cessation of external influence on one or more sensory organs)," RT reports.

In several cases, the experiments were conducted without the consent of many of the American citizens who served as guinea pigs.  They were done through "routine medical procedures in prison medical centers, detoxification clinics and juvenile detention centers," the Russian media highlights, while stressing that "in many cases under the direction of leading experts in behavioral sciences."

In addition, several of these programs were deployed in clandestine CIA locations where "federal narcotics agents" worked.

The memo indicates that these methods have been proven to "contribute decisively to the development of techniques that the Americans and their allies used in detention centers in Vietnam, Latin America, Afghanistan, Iraq, Guantanamo and secret prisons around the world."

Meanwhile, it highlights the induction of amnesia in "Russian agents suspected of working for both sides."
