    Abstract: An automatically extinguishable cigarette includes: a tobacco section in which tobacco is rolled up; a filter section; and an extinguishing member consisting of a cylindrical member provided between the tobacco section and the filter section and formed of a flame-resistant material. The front and rear openings of the cylindrical member are sealed by members formed of a material which is gas permeable but not water permeable. Further, the cylindrical member contains water or a fibrous material impregnated with water, thereby enabling the cigarette to go out by itself if left unextinguished.
