All residents aged 15 years and above from all the selected households were included in this study. A standardized pre-tested structured questionnaire was used in this study. Out of 1025 respondents interviewed the prevalence of ever and current smokers was 34% and 25.1% respectively.The prevalence of ever smokers and current smokers was significantly higher In males as compared to females (p.<0.001). The mean initiation age for the males current smokers was 10.4 (95% CI = 19.4, 21.5) years with a range from 7 to 66 years. For the females the mean initiation age was 31 (95% Cl =26.8, 35.2) years with a range from 15 to 64 years. The difference between the mean initiation age between male and female smokers was statistically significant (p<0.0001). The overall mean duration of smoking was 23.9 years with a median of 23 years. It ranged from less than 1 year to 66 years. There was no significant difference between the mean duration of smoking between male and females current smokers (p =0.59).
