Cigarettes which yield very low levels of sidestream “tar”during use comprise a paper wrapper having an air permeability of less than about 10 CORESTA units, and a blend of a tobacco filler material and a second smokable material. The second smokable material preferably includes about 60 weight percent calcium carbonate, about 30 weight percent pyrolyzed alpha-cellulose and about 10 weight percent carboxymethyl cellulose. Such cigarettes, when used, generate very low amounts of sidestream “tar,”and hence, very low levels of visible sidestream smoke.
