Recent developments in the pharmacotherapy of substance abuse

Modern concepts of addictive disorders emphasize the compulsive and relapsing drug-taking behaviors rather than tolerance and physical dependence. As with any chronic disorder, long-term treatment is necessary and medications may aid in the rehabilitative process. Specific medications have been demonstrated to be helpful for psychiatric disorders coexisting with addiction. Medications have also been demonstrated in controlled studies to aid in the rehabilitation of patients dependent on nicotine, alcohol, or opiates. Thus far, no medication has been clearly demonstrated to benefit patients suffering from abuse or dependence on cocaine, cannabinoids, nonalcohol sedatives, or hallucinogens.
