According to researchers at Washington University School of Medicine, smoking cessation does not counteract and can possibly help recover from mood and anxiety disorders and substance use disorders. A sample of 5,000 daily smokers, with past history of drug use disorder, alcohol use disorder or mood and anxiety disorder, completed the National Epidemiological Survey on Alcohol and Related Conditions, and were interviewed again 3 years later. It was found that at follow-up, about 60% had reduced smoking and 19% were abstinent. Individuals who quit were less likely to have a relapse of their behavioral health condition. Although it cannot be inferred that cessation will decrease risks, it can be said that cessation is consistent with recovery from these behavioral health conditions.
