Abstract
A combustible smokable filler material includes an agglomerated matrix filler having an inorganic component (e.g., particles of calcium carbonate) and a carbonaceous component (e.g., calcined molasses). The smokable filler material includes a binding agent and an aerosol forming material. Tobacco extracts and/or pieces of tobacco laminae can be incorporated into the smokable filler material, and/or the smokable filler material can be blended with tobacco cut filler. Cigarettes are provided by wrapping the smokable filler material in a paper wrapping material. A typical paper wrapping material has a porosity of less than about 5 CORESTA units.
