Drug addiction, a chronic relapsing disorder, causes an enormous burden to patients, families, and societies. This chapter summarizes current concepts of drug addiction, epidemiology, etiology, pathogenesis, pathology, clinical course, laboratory findings, assessment, and treatment on drug addiction. Pathologic consequences from drugs of abuse (e.g., opioids, sedatives, amphetamines, cocaine, cannabis, tobacco, phencyclidine, hallucinogens) are explained as well. The understanding of drug addiction has improved by recent progress in genetics, neuroscience, pharmacology, and psychiatry. It is now possible to treat drug addiction more effectively using advanced psychological and pharmacological interventions.
