Abstract

An extruded, coherent, multistrand, tobacco-containing, generally cylindrical smoking article and a process for making it are disclosed. The smoking article contains a plurality of strands that are adhered to one another so as to form passageways between the strands, the passageways extending generally along the longitude of the smoking article. The configuration of the strands and passageways provides sufficient heat transfer area and/or residence time for the smoke drawn by a smoker to cool to an acceptable level.
