Drug treatment effectiveness: an examination of conceptual and policy issues

This paper discusses different concepts or views of what constitutes effective treatment for drug dependence and how these views are involved in policy decisions regarding treatment. The paper reviews the rise of evidence-based medicine, discusses the emergence of efficacy research, effectiveness research, and other types of outcome-based evaluations of drug user treatment, but notes that despite a growing consensus among researchers on the effectiveness of drug user treatment, substantial public skepticism about the value of treatment still exists in the United States. The paper argues that one of the primary reasons for the lack of public consensus in the United States is that there is wide disagreement over which type of problem drug dependence is and for whom it may be a problem. The paper reviews some of the most common models and their implications for evaluating effectiveness, and argues that it is the differences in perspective among these models that are at the heart of policy debate over drug treatment policy in the United States. The paper concludes that because evaluation research as currently practiced does not address these issues, its utility for policy purposes is limited in the American context.
