Cigarettes are [[addiction|addictive]] due to the presence of the toxic chemical nicotine, which is a defensive pesticide produced by the plants for protection. Even occasional use carries a high risk of causing [[asthma]], [[emphysema]], [[heart attack]], [[stroke]], [[brain damage]], [[cancer]] of the [[lung]] and [[mouth]], and severe damage to the [[fetus]] of a [[pregnancy|pregnant woman]]. Cigarettes also contain unusually high levels of [[radiation]] due to the presence of [[radium]] and [[polonium]], and they contain traces of [[cyanide]], ammonium, formaldehyde, and other toxic chemicals used in curing the tobacco of manufactured cigarettes. The presence of these chemicals further exacerbating health problems. Numerous studies have shown that on average, nonsmokers live 10 years longer than smokers.

A cigarette works as follows: The tobacco is lit and the resulting smoke is inhaled by sucking it through the cigarette. This encourages the rest of the tobacco to burn. Cigarettes often have a filter on the mouth end, to provide a smoother and cleaner smoke, for increased ease of inhaling and also for improved taste.
