Abstract
A method of making smoking articles wherein a combustible tobacco material is mixed with one or more other ingredients including a liquid, the mixture being subjected to further processing to produce a shaped coherent mass having a through passage. Shaping is effected by application of pressure to the mixture to form the coherent mass, and is followed by drying of same, the mixture composition being selected and the shaping pressure and drying being controlled to impart to the shaped mass a porosity and density such as to substantially occlude gas flow therethrough and a porosity sufficient to support combustion of the shaped mass when ignited.
