OBJECTIVES This systematic review of the literature looked at data on pharmacological and non-pharmacological strategies of smoking cessation and reduction of consumption in patients with schizophrenia. METHOD The research was conducted on Medline for the period 1980-2018. We included randomized controlled trials, including preliminary studies of stable schizophrenic patients with no other severe psychiatric disorder and no other substance use than tobacco, treated with antipsychotic medications. Individual or group smoking cessation programs with or without pharmacological treatment, including a validation of abstinence, were included. RESULTS Pharmacotherapies for nicotine dependence-nicotine replacement therapy (n=3), bupropion (n=6), varenicline (n=8), association of medications (n=4)-were used in 23 studies combined with behavioral support. Compared to the placebo, bupropion and varenicline at the end of treatment were found to be the most effective pharmacotherapies to stop or reduce smoking and control craving. All the medications were well tolerated and did not lead to aggravation of psychosis or changes in symptoms. Non-pharmacological interventions: behavioral and cognitive therapies (n=5) combined with pharmacological treatment facilitated the management of smoking risk situations and improved adherence to antipsychotics; other psychosocial interventions (n=7) allowed the development of social skills; contigency management strategies with financial reinforcement can be used (n=4); the practice of physical activity and the use of an electronic cigarette allowed reduction of tobacco consumption. The results of transcranial electromagnetic stimulation studies (n=6) were discordant. Atypical antipsychotics appear to be associated with a better success of attempts to stop smoking. CONCLUSION Smoking cessation strategies for patients with schizophrenia appear to be effective and should combine (1) smoking cessation medications with sufficient duration, (2) diversified psychosocial approaches and (3) physical activity practice.
