Smoking ban

Over 42 million adults in the U.S. and over a billion individuals worldwide are cigarette smokers. In the U.S. alone, smoking tobacco is related to over 400,000 premature annual deaths. Furthermore, the average life expectancy of a smoker is 10 years less than that of a non-smoker. In addition to nicotine, cigarettes contain about 600 ingredients that form over 7,000 compounds when burned, of which at least 69 are known to be carcinogenic. Secondhand smoke exposes non-smokers to the same toxins, increasing the number of people subject to health risks from smoking.
