Cigarette smoking among first-year medical students in Yugoslavia and their academic success.

Abstract The prevalence of smoking among 317 first-year medical students was estimated to be 25.9%. The freshmen were interviewed about their smoking habits and followed for a period of two years. Academic success was assessed in terms of regularity of studying and the mean grade. The results of this cohort study did not reveal any significant association between smoking and the indicators of success either for men or women.
