Psychoactive

Explains how the nine systems of the human body are affected by each of the five classifications of psychoactive drugs--sedative hypnotics, opiates, stimulants, psychedelics, and alcohol. Demonstrates how the body's systems function, singularly and in concert, illustrating how a drug meant for one body system throws the other systems into disequilibrium. Discusses tolerance, withdrawal and dependence. Presents commentaries by rock promoter Bill Graham and comedian George Carlin.
