Smoking is the leading preventable cause of morbidity and premature death. In Brazil, it is estimated that there are around 200,000 annual deaths related to tobacco. Medical education is an important tool in the control and prevention of smoking. The beginning of college life can be made in a period of difficult adjustment, becoming vulnerable to the initiation and maintenance of tobacco use. Tobacco control measures have been applied in recent years directed primarily to this population. The objective was to quantify the prevalence of smoking and smoking-related attitudes of medicine students of the University Severino Sombra (USS) in Vassouras -RJ. A cross-sectional study was conducted with 199 students of 5th, 6th and 7th semesters of Medicine, University Severino Sombra (USS) of the second half of 2013. Questionnaires were applied after explanation of the survey containing questions about biological and demographic factors besides smoking among parents. Ninety two students (46.2%) were smokers, occasional smokers or former smokers; 107 (53.8%) reported never having smoked. The number of students smoking was considered high, and information about the harmful effects of smoking should be intensified especially among medical students for their importance as health example for the general population.
