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. The smoking article possesses an overwrap (e.g., a single paper overwrap) that extends over the longitudinally extending surface of the mouth end piece segment, the aerosol generation segment, at least a portion of the length of the heat generation segment, any segment located between the mouth end piece and aerosol generation segments, and at least a portion of the length of the optional lighting end segment. Alternatively, the smoking article possesses an overwrap (e.g., a single paper overwrap) that extends over the longitudinally extending surface of the aerosol-generating segment, at least a portion of the length of the heat generation segment, at least a portion of any segment located downstream from the aerosol-generating segment, and at least a portion of the length of the optional lighting end segment, thereby forming a cigarette rod; and the cigarette rod is connected or attached to a filter element using a tipping type of material and arrangement.

A smokable rod for a smoking article, such as a cigarette, possesses a co-axial or concentric construction. A longitudinally extending inner core of tobacco cut filler is positioned within a smokable rod. The outer material that circumscribes the inner core in an annular fashion is composed of a tobacco material treated with a burn suppressing agent, and the outer material acts as a substrate for an aerosol forming material. In use, one end of the smokable rod is lit, and the tobacco cut filler of the inner core burns to yield tobacco smoke. The outer material smolders, and hence thermal decomposition products of the outer tobacco material and volatilized aerosol forming material are produced. When the opposite end of the smokable rod is drawn upon, an aerosol composed of tobacco smoke, thermal decomposition products of tobacco, and volatilized aerosol forming material, is provided.

The present invention relates to smoking articles such as cigarettes, and in particular to catalytic systems containing metallic or carbonaceous particles that reduce the content of certain harmful or carcinogenic substances, including polyaromatic hydrocarbons, tobacco-specific nitrosamines, carbazole, phenol, and catechol, in mainstream cigarette smoke and in side stream cigarette smoke.

The present invention includes a method and apparatus for detecting exposure to environmental tobacco smoke by analyzing a sample of breath using electronic sensor technology, including surface acoustic-wave gas sensor technology. The method determines the presence and concentration of substance(s) (or a class of substances) indicative of environmental smoke exposure. Diagnostic software is used to identify substances where a stored library of signatures is compared to the signature obtained from the system. Signal processing and neural networks are preferably utilized in the analysis.
