Significant reductions in cigarette use were found among U.S. adults with major depression, substance use disorder, or both from 2006 to 2019, according to a new analysis of nationally representative survey data published today in JAMA. The study was conducted by researchers at the National Institute on Drug Abuse (NIDA), part of the National Institutes of Health, and the Substance Abuse and Mental Health Services Administration (SAMHSA). These findings suggest that groups at higher risk of cigarette smoking can be reached by, and may have benefitted from, tobacco use prevention and cessation efforts that have led to significant declines in tobacco use in the general population. At the same time, the findings highlight remaining disparities, documenting higher smoking rates in people with psychiatric disorders than in those without.

"This study shows us that, at a population-level, reductions in tobacco use are achievable for people with psychiatric conditions, and smoking cessation should be prioritized along with treatments for substance use, depression, and other mental health disorders for people who experience them," said Nora Volkow, M.D., director of NIDA and co-author of the study. "Therapies to help people stop smoking are safe, effective, and may even enhance the long-term success of concurrent treatments for more severe mental health symptoms in individuals with psychiatric disorders by lowering stress, anxiety, depression, and by improving overall mood and quality of life."

Cigarette smoking, the leading preventable cause of disease, disability and death in the U.S., has been declining. Experts attribute this in part to increases in available treatments, insurance coverage of these treatments, cigarette prices, smoke-free and tobacco-free policies, mass media and educational campaigns and other evidence-based strategies to help people avoid or quit using cigarettes that have been implemented in recent decades.
