Mang people around us have developed the habit of smoking,and some of them are even addictted to it.But they don't what price would they pay for that. The tobacco would produce lots of harmful and poisonous smoke after it is lighted up.And the smoker breathe thoses poisonous and hot smoke right into their lungs through the respiratory tract.This cause a huge hurtness to the both respiratory tract and lungs.And people who smoke are more possibly to get a cancer and some related diseases. So I suggest you to be away from the cigarette and cherish your health
