This paper summarizes some of the causes of, and some of the health and social concerns from, the growing illicit drug problem in the 1980s. It suggests that two recent developments, the decentralization of much drug production and modification to chemical laboratories in homes, and the application of increasingly innovative marketing techniques, have brought us to a new and more hazardous era of drug abuse. The new designer drugs and the new developments in cocaine abuse reveal these to be of major concern to the medical and public health professions, as well as a major worry to the public. In the absence of effective elimination of illegal drugs from the environment, attention must focus on alternative ways to reduce drug abuse. Education regarding the nature of the hazards of these drugs must increase, but there are no simple methods for reducing drug use. We must be prepared to fight growing drug abuse for some time to come.
