Cigarette
A cigarette (French "small cigar", from cigar + -ette) is a product consumed through smoking and manufactured out of cured and finely cut tobacco leaves and reconstituted tobacco, often combined with other additives, then rolled or stuffed into a paper-wrapped cylinder (generally less than 120 mm in length and 10 mm in diameter). The cigarette is ignited at one end and allowed to smoulder for the purpose of inhalation of its smoke from the other (usually filtered) end, which is inserted in the mouth. They are sometimes smoked with a cigarette holder. The term cigarette, as commonly used, refers to a tobacco cigarette but can apply to similar devices containing other herbs, such as cannabis.
Rates of cigarette smoking vary widely. While rates of smoking have leveled off or declined in the developed world, they continue to rise in developing nations.
A cigarette is distinguished from a cigar by its smaller size, use of processed leaf, and paper wrapping, which is usually white, though other colors are available. Cigars are typically composed entirely of whole-leaf tobacco.
Cigarettes are the most frequent source of fires in private homes and the European Union wishes to ban by 2011 cigarettes that are not fire-safe.
