Then one or two more households in the neighborhood of each of the former households were also selected. Finally, in each household a 30-70 year old person was randomly selected and asked to complete a questionnaire.   Results: The overall prevalence of current cigarette smoking in men 30-70 years old was 24.1% (95% confidence interval: 22.1-26.1%).18.3% of them were daily and 5.8% occasional smokers. 26.8% of rural and 23.0% city resistant adults were cigarette smokers (P=0.053).
