Documents reveal mind-control experiments conducted by the Central Intelligence Agency.
Date: 1977
The documents show that 142 people who were labeled "sexual psychopaths" and were incarcerated at Ionia State Hospital in Michigan were given psychotropics and marijuana to test the amounts needed to interrogate and, "unlock their secret thoughts."
In particular, the experiment was designed “to test the effectiveness of certain medication in causing individuals to release guarded information under interrogation" (NYTimes, 1977).
