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 and polonium, further exacerbating health problems. Numerous studies have shown that on average, nonsmokers live 10 years longer than smokers.
