Cigarettes 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 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 the undeveloped world.
A cigarette is distinguished from a cigar by its smaller size, use of processed leaf, and paper wrapping, which is usually white, though other colours are available. Cigars are typically composed entirely of whole-leaf tobacco.
Commercially manufactured cigarettes are seemingly simple objects consisting mainly of a tobacco blend, paper, PVA glue to bond the outer layer of paper together, and often also a cellulose acetate
