Pharmacotherapy, as a means of treating drug addiction in combination with other treatment modalities, has received too little attention from the research community, the pharmaceutical industry, public health officials, and the federal government. Medications to combat drug addiction could have an enormous impact on the medical consequences and socioeconomic problems associated with drug abuse, both for drug-dependent individuals and for American society as a whole. This book examines the current environment for and obstacles to the development of anti-addiction medications, specifically those for treating opiate and cocaine addictions, and proposes incentives for the pharmaceutical industry that would help overcome those obstacles and accelerate the development of anti-addiction medications.
