Environmental tobacco smoke (ETS), also known as secondhand smoke, has MORE toxic compounds than directly inhaled tobacco smoke.
Cigarette smoke contains over 40 compounds that are known to be toxic or carcinogenic. These include poisonous gases, carcinogenic compounds and particulate matter. Smoke sucked through a lighted cigarette and inhaled by the smoker has been burned at a higher temperature then the smoke that is coming off the end of the cigarette. This higher temperature burning destroys or inactivates certain of the toxic compounds.
