Tobacco-Containing Smoking Article

A smoking article may include a cigarette incorporated within an electrically powered aerosol generating device that acts as a holder for that cigarette. The smoking article possesses at least one form of tobacco. The smoking article also possesses a mouth-end piece that is used by the smoker to inhale components of tobacco that are generated by the action of heat upon components of the cigarette. A representative smoking article possesses an outer housing incorporating a source of electrical power (e.g., a battery), a sensing mechanism for powering the device at least during periods of draw, and a heating device (e.g., at least one electrical resistance heating element) for forming a thermally generated aerosol that incorporates components of tobacco. During use, the cigarette is positioned within the device, and after use, the used cigarette is removed from the device and replaced with another cigarette.

Smoking article

A smoking article, such as a cigarette, comprises a lighting end and a mouth end. The smoking article possesses an aerosol-generation system that includes (i) a heat generation segment, and (ii) an aerosol-generating region or segment. A mouth end piece segment can be located at the mouth end of the smoking article. A segment of tobacco cut filler, gathered tobacco paper, or other type of flavor source material, can be positioned between the mouth end piece segment and the aerosol-generation segment. Optionally, segment composed of tobacco cut filler can be positioned so as to provide a lighting end segment.
