Edgewood Guinea Pigs

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.

¶ The images presented here are stills from documentary

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