Abstract

The cost to society of alcohol, tobacco, and illicit drug dependence is enormous. Although the importance of treatment for substance abuse to public health is increasingly acknowledged, pharmacotherapy is generally underutilized. However, the selection of medications for clinical testing is increasingly guided by the rapidly evolving science of addictive drugs and behavior. The benefit of medication for smoking cessation is firmly established, particularly for nicotine replacement and antidepressant therapy. Naltrexone is an important addition to the pharmacopoeia, and acamprosate may soon be approved as well. Although no new medications are approved for cocaine and amphetamine abuse, a variety of candidate treatments have shown promise in ongoing studies. Opiate substitution therapy is highly effective for rehabilitation of heroin addiction, and several alternative forms will soon be available; alternative forms of opiate detoxification have also received attention. Overall, there is increasing recognition that physicians have an obligation to identify and treat all forms of substance dependence, although knowledge of the efficacy of the available treatments is steadily increasing.
