The collected data was statistically analyzed applying SPSS software (ver. 20), via χ2 and logistic regression tests. Results: 85% of students mentioned they had not had smoking experience, and 15% reported experience of smoking. The prevalence of smoking among the boys was 15/3% and it was reported 12/2% within the girls.
