ABSTRACT:
A cigarette including a longitudinally segmented combustible fuel element, and a substrate carrying tobacco extract and glycerin positioned physically separate from the fuel element is disclosed. The substrate is a gathered paper-type material, and is positioned in a spaced apart relationship from the fuel element. One preferred smoking article of the present invention is a cigarette which comprises (i) a symmetrical and longitudinally segmented combustible fuel element; (ii) a physically separate aerosol generating means including at least one aerosol forming material; and (iii) means for securing, maintaining or retaining the fuel element within the smoking article. The symmetrical fuel element of the present invention comprises two substantially identical end segments; a longitudinally disposed intermediate segment; and two, preferably identical, reduced cross-sectional area (or reduced circumference) segments (also called "isolation" segments) located between each of the end segments and the intermediate segment. The symmetrical nature of the fuel element allows it to be inserted into the cigarette without concern as to any particular longitudinal orientation. Thus, when placed in a cigarette, one end segment of the fuel element serves as a burning segment, while the other end segment serves as a base segment.
