LSD Blotter Paper Art

Beginning in the 1950s the US Central Intelligence Agency began a research program code named Project MKULTRA. Experiments included administering LSD to CIA employees, military personnel, doctors, other government agents, prostitutes, mentally ill patients, and members of the general public in order to study their reactions, usually without the subject's knowledge. The project was revealed in the US congressional Rockefeller Commission report in 1975.
In 1963 the Sandoz patents expired on LSD. Also in 1963, the US Food and Drug Administration classified LSD as an Investigational New Drug, which meant new restrictions on medical and scientific use. Several figures, including Aldous Huxley, Timothy Leary, and Al Hubbard, began to advocate the use of LSD. LSD became central to the counterculture of the 1960s. On October 24, 1968, possession of LSD was made illegal in the United States. The last FDA approved human study with LSD, for use in dying cancer patients, ended in 1980. Legally approved and regulated psychiatric use of LSD continued in Switzerland until 1993. Today, medical research is resuming around the world.
