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 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. A metal cartridge is radially spaced from the longitudinal outer periphery of the burning segment of the fuel element. A retaining member grasps the base segment of the fuel element and holds the fuel element securely in place within the cigarette.
