ABSTRACT:
The segmented cigarette includes combustible inside and outside tubular walls that are spaced from each other by ridges extending therebetween. The inside wall holds a plurality of elongated segments of tobacco aligned end to end. Different tobaccos may be utilized in each segment. The upstream, axial end of each segment is sealed by paper. The inside wall includes a plurality of gas passages therethrough near the axial end seal such that gas from the burning end of the cigarette passes through those passages into the interspace between the outside and inside walls, expands and cools. This cooling and expansion reduces the accumulation of noxious substances in the segments of tobacco downstream.
