During the first semester of the 1971-72 academic year, students at 7 universities located in urban areas across the U.S. participated in an interdisciplinary program that was designed to help the students develop problem-solving techniques. The particular problem that the students attacked was that of drug addiction. This problem incorporated the fields of sociology, social psychology, economics, public administration, political science, and the health sciences. Students studied the use of heroin in their own cities and the methods being taken to combat heroin use, and made recommendations based on their findings designed to solve or to ameliorate the heroin use in that city.
