title: Nicotine dependence and psychiatric disorders in the United States: results from the national epidemiologic survey on alcohol and related conditions.
abstract: BACKGROUND
  No information is available on the co-occurrence of DSM-IV nicotine dependence and Axis I and II psychiatric disorders in the US population.
  
  
  OBJECTIVE
  To present national data on the co-occurrence of current DSM-IV nicotine dependence and other psychiatric disorders by sex and to estimate the burden of all US tobacco consumption carried by nicotine-dependent and psychiatrically ill individuals.
  
  
  METHODS
  Face-to-face interviews.
  
  
  METHODS
  The United States.
  
  
  METHODS
  Household and group-quarters adults (N = 43 093).
  
  
  METHODS
  Prevalence and comorbidity of current nicotine dependence and Axis I and II disorders and the percentage of cigarettes consumed in the United States among psychiatrically vulnerable subgroups.
  
  
  RESULTS
  Among US adults, 12.8% (95% confidence interval, 12.0-13.6) were nicotine dependent. Associations between nicotine dependence and specific Axis I and II disorders were all strong and statistically significant (P<.05) in the total population and among men and women. Nicotine-dependent individuals made up only 12.8% (95% confidence interval, 12.0-13.6) of the population yet consumed 57.5% of all cigarettes smoked in the United States. Nicotine-dependent individuals with a comorbid psychiatric disorder made up 7.1% (95% confidence interval, 6.6-7.6) of the population yet consumed 34.2% of all cigarettes smoked in the United States.
  
  
  CONCLUSIONS
  Nicotine-dependent and psychiatrically ill individuals consume about 70% of all cigarettes smoked in the United States. The results of this study highlight the importance of focusing smoking cessation efforts on individuals who are nicotine dependent, individuals who have psychiatric disorders, and individuals who have comorbid nicotine dependence and other psychiatric disorders. Further, awareness of industry segmentation strategies can improve smoking cessation efforts of clinicians and other health professionals among all smokers and especially among the most vulnerable.
