Abstract: This invention concerns the use of specific coatings that are applied to the paper wrapper that encloses the cigarette's smoking medium for limiting in a predictable manner the free burning time of the treated cigarette, or controlling the lapsed time prior to self-extinguishment after being lit and left unattended.

Comparable behaviors are obtained, for equivalent weight percentages of the deposited solids, by either precoating the portion of paper wrapper that subsequently encloses the charge of tobacco or by post-treatment of the external surface of the assembled cigarette.
