Cigarette smoking is an intractable public health problem and health care providers play a important role in the effort to reduce the prevalence of smoking. Our outpatient smoking cessation clinic started working in April 2000. Since then it has been servicing once a week by appointment. After smoking habits and sociodemographic features of the people were asked all individuals attended a suitable smoking cessation program. The results were analyzed with Chi-square test and Kaplan Meier survival analysis. It was observed that 226 people, 97 (42.9%) women and 129 (57.1%) men, visited the polyclinic during this period. The average age was 37.8 +/- 11.8 years. The rate of the smoking cessation was 43.4% at the end of the year. There were no relations between smoking cessation and initial age (p= 0.677), duration of smoking (p= 0.367), number of daily cigarette (p= 0.712), and nicotine addiction level (p= 0.673) and education level (p= 0.131). We think that our results are important to show the importance of professional support in stopping smoking.
