This is a descriptive study to determine the smoking prevalence and attitudes with smoking among high school students in Sivas, Turkey. This study was carried out in 6 high schools located in Sivas, Turkey. The sample was constituted by 1050 students. The data of the study was obtained by a questionnaire which is developed by researchers. The x2 test was used in the statistical analyses. In this study, the rate of students who did not smoke or stopped smoking was found to be 79.6%, while the rate of occasionaly or daily smokers was 20.4%. Students with male gender, those whose fathers and mothers had a low educational level, and a smoking mother, father or sibling, had a higher frequency of smoking (p<0.05). Students were found to have opposite attitudes to cigarette in general and rates of agreed to some attitude expressions were found to be higher in non-smoking students. The results demonstrated that the smoking prevalence among high school students was high and students with a smoking family member in particular, those with parents having low educational levels and of male gender should be regarded as a risk group for smoking.
