Nicotine withdrawal in US smokers with current mood, anxiety, alcohol use, and substance use disorders

Background: The current study examined tobacco withdrawal symptoms and withdrawal-related discomfort and relapse in smokers with and without current mood disorders, anxiety disorders, alcohol use disorders (AUD), and substance use disorders (SUD). Methods: The subsample of current daily smokers (n = 8213) from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC, Wave 1,2001-2002, full sample n = 43,093) were included in these analyses. Cross-sectional data compared smokers with and without current psychiatric disorders on withdrawal symptoms using logistic regression models. The effects of having a co-morbid psychiatric disorder and AUD/SUD compared to a psychiatric disorder alone on nicotine withdrawal were also examined. Results: Participants with a current mood disorder, anxiety disorder, AUD, or SUD were more likely to report withdrawal symptoms and reported more withdrawal symptoms than those without current disorders. Having a current mood disorder, anxiety disorder, or SUD was also associated with increased likelihood of withdrawal-related discomfort and relapse. There were no significant interactions between psychiatric disorders and AUDs/SUDs on withdrawal symptoms or behavior. Conclusions: Participants with a current Axis I disorder were more likely to experience tobacco withdrawal symptoms and withdrawal-related discomfort and relapse. Having a co-morbid psychiatric disorder and AUD/SUD did not synergistically increase the experience of withdrawal-related symptoms or relapse. It is important to identify Axis I disorders in smokers and provide these smokers with more intensive and/or longer treatments to help them cope with withdrawal symptoms and prevent relapse.
