Review on Effects of Passive Smoking

Abstract

Smoking is injurious to health. Mainstream and Side stream smoking both are actively and passively injurious to health. Ill effects of Secondhand smoking are more commonly underrated in the society. Side stream smoking also causes hazardous health effects. Smoking not only affects the smoker, but also affects non-smokers and children. Passive smokers are people exposed to cigarette smoke in two ways : by direct exposure to the smoke of passively burning cigarette and exposure to the smoke breathed out by the smoker. Second-hand smoke is the mixture of direct smoke from burning a cigarette along with the smoke breathed out from the smoker’s lungs. As a result, side stream smoke has higher concentration of some toxic and carcinogenic substances than the mainstream smoke. When exposed to second hand smoke, non-smokers inhale 60-80% of airborne nicotine similar to that absorbed by smokers So this review paper will elaborate about the effects of passive smoking.
