Between 1955 and 1975, the U.S. Army used 7,000 enlisted soldiers as human guinea
pigs for experiments involving a wide array of biological and chemical warfare agents.
These tests were conducted jointly by the U.S. Army Intelligence Board and the
Chemical Warfare Laboratories at Edgewood Arsenal's research facility in
Maryland. Approximately 3,500 of these soldiers were given doses of
powerful mind-altering psychochemicals, including LSD, PCP, and
BZ. These "volunteer" test subjects were not told which drugs they
were given, and were not fully informed of the extreme physical
and psychological effects these drugs would have on them.

footage of these experiments filmed by the U.S. Army.
