Dr. Theodore R. Vallance is a social psychologist whose research and writings have focused on the subjects of drug policy, "trade-off analysis," and the economic and social costs of the drug problem. In his recent book on drug policy, Prohibition's Second Failure: The Quest for a Rational and Humane Drug Policy, Vallance gives a picture of the American drug problem and the ideological base that maintains it. He analyzes economic and social costs of the drug problem, including the costs incurred by the war on drugs. Reporting recent economic cost data on the drug problem, the book offers criteria for evaluating the effectiveness of U.S. drug policy and discusses its successes and failures.Before his current appointment at Penn State University, Dr. Vallance was the chief of planning for the National Institute of Mental Health, and was responsible for the first NIMH report recommending a tempering of the drug war. NIMH funded two major projects he developed, involving extending mental health aspects of social planning (1973-79), and studying indigenous care-giving networks in primary prevention (1977-81). He has edited Values and Ethics in Human Development Professions (1984), and Mental Health Services in Transitions: A Policy Sourcebook (1983).Professor Vallance earned his MA in Psychology (1941) and Ph.D. in Social Psychology (1950) from Syracuse University.
