Abstract
This review of cocaine use in the general population included the historical background of evolving scientific knowledge of cocaine's dependency-producing property, the role of amphetamines in delaying the widespread nonmedical use of cocaine, and various drug control regulations. It examined the characteristics of users during 1972 to 1985, the period of increased cocaine use. Trends show that cocaine use is related to a complex mix of its availability, pharmacological properties, and societal attitudes toward its addictive or harmful consequences.
