what smoking does to people around you
Secondhand smoke is the combination of smoke from a burning cigarette and smoke exhaled by a smoker. There are two types of secondhand smoke; side stream smoke comes directly from the burning tobacco product, and mainstream smoke is the smoke that the smoker inhales. The smoke that burns off the end of a cigarette or cigar actually contains more harmful substances than the smoke inhaled by the smoker
