Project MK-ULTRA, or
MKULTRA, was the code name for a covert
CIA mind-control and
chemical interrogation research program, run by the
Office of Scientific Intelligence. The program began in the early 1950s, continuing at least through the late 1960s, and it used United States citizens as its test subjects.
[1][2][3] The published evidence indicates that Project MK-ULTRA involved the surreptitious use of many types of drugs, as well as other methods, to manipulate individual mental states and to alter brain function.
