A smokable filler material includes an aerosol forming material (e.g., propylene glycol and glycerin) and a binding agent (e.g., ammonium alginate). 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. The amount of aerosol forming material within the smokable filler material typically is at least about 20 percent, based on the weight of that smokable filler material. 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. Cigarettes cn include two layers of circumscribing paper wrapping materials. Cigarettes also can include filter elements.
