Tutorial
| 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. |
