Résumé
When a cigarette is smoked, about one-half of the smoke generated is side stream smoke. This form of smoke contains essentially all of the same carcinogenic [cancer causing] and toxic agents that have been identified in the mainstream smoke inhaled by the smoker, but at greater levels. As smoking from different sources is pollution and injurious to health, so we planned to carry out cigarette smoking survey of citizens of different localities of Mansehra. The study was carried out on 2100 subjects residing in different localities of Mansehra. A specifically designed questionaire was filled individually. Out of the study population 850 [40.48%] were found to be indulged in cigarette smoking. The study suggested that smokers should avoid smoking for the sake of their health
