Abstract: In a preferred embodiment, a filter-tip cigarette having embodied within the filter-tip and extending into the compacted tobacco of the smoking-portion of the cigarette, a compressible enclosed vessel having a spout ending in a small wax-plugged hole from which hole the plugging-wax is ejectable by pressurized contents within enclosed space of the enclosed vessel pressurized by either or both decomposed carbonic acid by resulting carbon dioxide gas and compacting pressure on the exterior walls of the enclosed vessel resulting from compressing pressure applied to exterior walls of the filter-tip such as by compressing the filter tip between the teeth or pressing the same by stepping on it thus wetting and extinguishing the burning tobacco.
