Adults who smoke cigarettes and are addicted to alcohol or other drugs were more likely to achieve sustained remission of their substance use disorder symptoms if they also quit smoking, according to scientists at the National Institutes of Health (NIH). Based on their analysis of data from a large U.S. study of smoking and health, researchers believe the results clearly show the benefit of pairing smoking cessation with addiction recovery efforts.

“We now have strong evidence from a national sample that quitting cigarette smoking predicts improved recovery from other substance use disorders,” explained Nora Volkow, M.D., director of NIH’s National Institute on Drug Abuse (NIDA), which partly funds the study, known as the Population Assessment of Tobacco and Health (PATH) Study. “It underscores the importance of addressing different addictions together, rather than in isolation.”
