Project MK-ULTRA, or also known as MKULTRA is a code name for a secret CIA mind control program that included chemical research. It was run by the Office of Scientific Intelligence. It began in the early 1950's and went until at least the late 1960's. MK-Ultra used United States citizens as test subjects. Evidence published shows that MKULTRA secretly used many different drugs and other methods, to change a person's mental state and brain function.
