I am not harming anyone while smoking.
Tobacco smoke is harmful for people around you. Smoke in the air from others' cigarettes contains toxic chemicals including tar, nicotine, carbon monoxide, arsenic and cyanide. Non-smokers who breathe it absorb these substances and are at risk for the same serious health consequences as smokers. It's been estimated that a waiter or waitress who works a single eight-hour shift in a smoky bar inhales as much toxic smoke as a pack-a-day smoker.
