Abstract
The present invention is directed to a smoking article which produces an aerosol that resembles tobacco smoke but which preferably contains no more than a minimal amount of incomplete combustion or pyrolysis products. The preferred smoking article of the present invention provides an aerosol 'smoke' which is chemically simple, consisting essentially of air, oxides of carbon, water, and the aerosol which carries any desired flavor or other desired volatile materials as well as trace amounts of other materials. In addition to a mouthend piece, an especially preferred embodiment of the present smoking article comprises a short combustible carbonaceous fuel element which is less than about 30 mm in length prior to smoking. The fuel element is disposed longitudinally relative to a physically separate aerosol generating means which comprises a porous nonparticulate substrate. The substrate includes one or more aerosol forming substances.
