(54)	Cigarette and smokable filler material therefor

(57) A combustibie smokabie filler material (20) includes an agglomerated matrix of an inorganic component (e.g., particles of calcium carbonate) and an organic component (e.g., an alginate). The smokable filler material also 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 filier material in a paper wrapping material (25). A typical paper wrapping material has a porosity of less than about 5 CORESTA units.
