Methods With stratiifed cluster sampling method, a questionnaire survey was carried out among 2 730 college students chosen from 4 universities in Baoding. Results 95.3%valid questionnaires were reclaimed. Among the 2 602 College Students, the proportion of smoking was 12.9%in total. There was a difference in the rate of current smoking between males(22.3%)and females(0.17%)(P<0.001). About the current smoking rate in male students, it had a tendency of getting worse in the higher grades(P<0.001). The passive smoking rate was 24.6%in 2 267 non-smokers, and the male students had a higher rate of passive smoking than female students(P<0.001). Their knowledge was limited although they had known a certain points about the harm of tobacco exposure. 38.2%of the students were disgusted very much with passive smoking, but only 16.3%of them would take the initiative to discourage the smokers from smoking. Conclusion Smoking and passive smoking among college students was popular. Their ability of refusing to smoke was weak. Active propaganda and health education for cigarette smoking and passive smoking control should be enforced in universities.
