BZ
from Acid Dreams: "It was from Hoffmann-La Roche in Nutley, New Jersey, that Edgewood Arsenal obtained its first sample of a drug called quinuclidinyl benzilate, or BZ for short. The army learned that BZ inhibits the production of a chemical substance that facilitates the transfer of messages along the nerve endings, thereby disrupting normal perceptual pattems. The effects generally lasted about three days, although symptoms--headaches, giddiness, disorientation, auditory and visual hallucinations, and maniacal behavior--could persist for as long as six weeks. "During the period of acute effects," noted an army doctor, "the person is completely out of touch with his environment."
Dr. Van Sim, who served as chief of the Clinical Research Division at Edgewood, made it a practice to try all new chemicals himself before testing them on volunteers. Sim said he sampled LSD "on several occasions." Did he enjoy getting high, or were his acid trips simply a patriotic duty? "It's not a matter of compulsiveness or wanting to be the first to try a material," Sim stated. "With my experience I am often able to change the design of future experiments.... This allows more comprehensive tests to be conducted later, with maximum effective usefulness of inexperienced volunteers. I'm trying to defeat the compound, and if I can, we don't have to drag out the tests at the expense of a lot of time and money." With BZ, Dr. Sim seems to have met his match. "It zonked me for three days. I kept falling down and the people at the lab assigned someone to follow me around with a mattress. I woke up from it after three days without a bruise." For his efforts Sim received the Decoration for Exceptional Civilian Service and was cited for exposing himself to dangerous drugs "at the risk of grave personal injury."
