Abstract
A smokable rod for a smoking article, such as a cigarette, possesses a co-axial or concentric construction. 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. A preferred aerosol forming material is glycerin. An outer paper wrapper circumscribes the length of the smokable rod, and another paper wrapping material also can circumscribe the inner core 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. Alternatively, a smokable rod can be provided by positioning the tobacco cut filler in the outer annular region, and by constructing the inner core portion using the tobacco material treated with aerosol forming material and a burn suppressing agent.
