Project MKUltra (or MK-Ultra), also called the CIA mind control program, was discontinued in 1973. One 1955 MKUltra document gives an indication of the size and range of the effort. It refers to the study of an assortment of mind-altering substances described as follows:
Substances which will enhance the ability of individuals to withstand privation, torture, and coercion during interrogation and so-called "brain-washing".
Among those drugs studied were LSD, heroin, morphine, temazepam (used under code name MKSEARCH), mescaline, psilocybin, scopolamine, alcohol and sodium pentothal.
Which drugs, if any, did Project MKUltra discover enhance an individual's ability to withstand brainwashing? Is this why these drugs came to be outlawed in the 1970s?
