Coated self-extinguished cigarette

A cigarette comprising a charge of tobacco wrapped in a cigarette paper wherein the wrapper is coated on its inner portion that contacts said tobacco with a fire proofing clay in an effective amount so that upon the burning of the cigarette the clay becomes brittle and cracks allowing air to penetrate into the combustion zone but physically segregating the combustion zone from its ambient surroundings and wherein said clay coating is divided into annular sections so that when the cigarette is smoked the separate clay sections will individually fall off.
