The last 50 years have seen important reductions in cigarette smoking in the United States. However, these reductions have been unevenly distributed, and rates of cigarette smoking remain elevated among individuals with psychiatric illness, including other substance use disorders (SUDs). Psychiatrists are uniquely positioned to address this disparity, having both the skills to treat tobacco use disorder and regular contact with patients more likely to smoke. In this Viewpoint, we advocate that evaluating for and offering treatment for tobacco use disorder should be a core part of psychiatric practice.
