Cocaine poses interesting problems for neurophysiologists and neuropharmacologists and there is important new data on the effects of cocaine on the brain (its initial site of action at the cellular level now appearing to be the dopamine transporter). Includes chapters on the far-reaching toxic effects of cocaine, on the epidemiology and the economics of drug addiction, on the past and present use of cocaine in the U.S. and in South America, and on the moral issues raised by drug use and abuse.
