This non-randomized, prospective and open clinical trial evaluated 172 smokers attended in a SCP based on cognitive behavioral treatment associated or not with medication therapy. Individuals were followed for 12 months. Statiscal analysis was performed using the R statistical software. For quantitative variables (age, pack years index and cigarettes/day) were used t-tests and for qualitative variables (gender, education level, lived with others smokers, medication therapy, nicotine dependence, socioeconomic, anxiety and depression level.) were used χ2 test. The influence of epidemiologic characteristics on smoking cessation (SC) in univariate and multivariate analyses was tested, calculating Relative Risks (RR) with confidence intervals of 95% (CI). Variables resulting in Pீ0.15 for univariate analysis were selected to enter into logistic regression model. Differences were considered significant at Pீ0.05. Results: 172 individuals were included, 126 (73%) started treatment, of which 61 individuals (48%) started abstinent and according the logistic model the individuals who used medication therapy had eight-fold more chances to started abstinence (P=0.0002 RR=8 CI 3-29). Thirty-three percente of individuals remained abstinent for 12 months and smokers with lower socioeconomic level had nine-fold more chances to return to smoking (P=0.005 RR=9 CI 2-57). Conclusions: The success rate of this program was 16% and medication, as well as socioeconomic status are predictors of success in SC. %U https://erj.ersjournals.com/content/erj/40/Suppl_56/P1970.full.pdf
