Addressing Criticisms of the Disease Model

Volkow, Koob, and McLellan on the neurobiology of addiction.The New England Journal of Medicine recently published a review article, “Neurobiologic Advances from the Brain Disease Model of Addiction,” authored by three prominent figures in the field of addiction research: Nora Volkow, the director of the National Institute of Drug Abuse (NIDA); George Koob, the director of the National Institute of Alcohol Abuse and Alcoholism (NIAAA); and Thomas McLellan, founder and chairman of the Treatment Research Institute in Philadelphia.  The article summarizes the research that has “increasingly supported the view that addiction is a disease of the brain,” and concludes that “neuroscience continues to support the brain disease model of addiction.” The implications of this, say the authors, are straightforward: “As is the case in other medical conditions in which voluntary, unhealthful behaviors contribute to disease progression (e.g., heart disease, diabetes, chronic pain, and lung cancer), evidence-based interventions aimed at prevention, along with appropriate health policies, are the most effective ways of changing outcomes.” And some of the implications are immediate: “A more comprehensive understanding of the brain disease model of addiction many help to moderate some of the moral judgement attached to addictive behaviors and foster more scientific and public health-oriented approaches to prevention and treatment.”In a supplementary appendix, the authors...
