Cigarette
A cigarette is a product typically comprised of cured tobacco leaves rolled in paper into a cylinder shape.
Cigarettes are addictive due to the presence of the toxic chemical nicotine, and 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 pregnant woman. Cigarettes also contain unusually high levels of radiation due to the presence of radium, 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.
