Abstract
A cigarette includes a longitudinally segmented combustible fuel element, and a substrate carrying tobacco extract and glycerin positioned physically separate from the fuel element. The substrate is a gathered paper-type material, and is positioned in a spaced apart relationship from the fuel element. The fuel element is composed of a carbonaceous material and is extruded in such a manner that when positioned within the cigarette, its extrusion axis is perpendicular to the longitudinal axis of the cigarette. The fuel element includes a burning segment at one end, a base segment at the opposite end, and an isolation segment between the burning and base segments. The fuel element is circumscribed by glass fibers so as to hold the fuel element in place within the cigarette.
