This paper reviews the activities of the Addiction Research and Treatment Corporation (ARTC), a substance abuse treatment agency, located in Brooklyn, New York, which services approximately 2,300 patients annually. ARTC's history, treatment, and research activities are first described. We then proceed to detail the ARTC's employee health maintenance and community relations programs. A multicomponent treatment model is then outlined, which emphasizes the interactive role of the above functions within an optimal treatment network.
