People with psychotic disorders are associated with high prevalence of cigarette smoking and prevalence rates. Studies show that many smokers with psychotic disorders would like to stop smoking, yet the abstinence rate among them is low. Despite this significant public health problem, few studies have examined the characteristics of this group of smokers and the predictors of smoking cessation.

This is a retrospective chart review study. Case records of smokers who attended our smoking cessation clinic with and without psychotic disorders were reviewed. The outcome measure was self-reported 7-day point prevalence abstinence rate at week 26. The basic demographic and biosocial characteristics of these smokers were analyzed.

A total of 3671 case records were reviewed and 155 smokers with psychosis were identified. The independent predictors of smoking abstinence at week 26 were to improve performance in exercise and sports, greater confidence of quitting, and greater number of counselling sessions. The 7-day point prevalence abstinence rate was 22.6% at 26 weeks.

This study has demonstrated that many smokers with psychosis are able to quit smoking even with NRT and counselling and without use of oral medications. Health professionals need to pay greater attention to tobacco use by individuals with mental disorders. Every effort should be given to enhance their motivation, build up their confidence and to provide adequate counselling sessions.
