The \u201cout-of-body\u201d intense psychological and behavioral effects of low doses of phencyclidine led to its abuse. In the late 1960s and 1970s, phencyclidine (\u201cangel dust\u201d) became a widely used hallucinogenic drug. The effects were often extreme, marked by acute psychosis and aggressive and violent behaviors, and overdoses led to many emergency room visits and deaths from status epilepticus, hyperthermia, rhabdomyolysis and subsequent renal, respiratory and hepatic failure."}]
