United States Penitentiary, Tucson. On July 27, 2020, Pickard was granted Compassionate Release from federal prison after serving 17 years of his sentence. Secret government research The U.S. Central Intelligence Agency (CIA) became interested in LSD when they read reports alleging that American prisoners during the Korean War were being brainwashed with the use of some sort of drug or "lie serum". LSD was the original centerpiece of the top secret MKULTRA project, an ambitious undertaking conducted from the 1950s through the 70s designed to explore the possibilities of pharmaceutical mind control. Hundreds of participants, including CIA agents, government employees, military personnel, prostitutes, members of the general public, and mental patients were given LSD, many without their knowledge or consent. The experiments often involved severe psychological torture. To guard against outward reactions, doctors conducted experiments in clinics and laboratories where subjects were monitored by EEG machines and had their words recorded. Some studies investigated whether drugs, stress or specific environmental conditions could be used to break prisoners or to induce confessions. The CIA also created The Society for the Investigation of Human Ecology, which was a CIA funding front which provided grants to social scientists and medical researchers investigating questions of interest related to the MKULTRA program. Between 1960 and 1963, the CIA gave $856,782 worth of grants to different organizations. The researchers eventually concluded that LSD's effects were too varied and uncontrollable to make it of any practical use as a truth drug, and the project moved on to other substances. It would be decades before the U.S. government admitted the existence of the project and offered apologies to the families of those who were forced to participate in the experiments. During this time period, the use of LSD for psychochemical warfare was under consideration and testing, among other substances. Looking to replicate the effects of nerve gas created by the Germans during World War II without the toxicity, LSD was sought for use under the pretense that it could induce hysteria and psychoses, or at least an inability to fight without wholesale destruction of the enemy and their properties. Thousands of tests on willing research subjects took place at the Edgewood Arsenal in Maryland, with the ultimate conclusion being that LSD was too unpredictable and uncontrollable for any tactical use. Recreational use From 1960 to 1980 LSD began to be used recreationally in certain (primarily medical) circles. Mainly
