Abstract
Substance use disorders represent complex phenotypes that result from the intricate interplay of genetic variation, neurobiological mechanisms, and psychosocial and environmental variables. To date, one of the least studied factors has been genetic variation. This chapter provides a critical review of the expanding literature on molecular genetics applied to the treatment of addiction. We begin with a brief overview of concepts in psychiatric genetics, followed by an extended review and discussion of pharmacogenetics and pharmacogenomics applied to addiction medicine. Next, we discuss practical and ethical issues in the translation of pharmacogenetics science into clinical practice. Lastly, we outline future directions for the field. Although personalized medicine is still largely incipient in the field of addiction, it holds considerable potential to improve the clinical care of individuals suffering from addictive disorders.
