ABSTRACT:
The present invention relates to a smoking article which produces an aerosol that resembles tobacco smoke, but contains no more than a minimal amount of incomplete combustion or pyrolysis products.
The smoking article of the present invention provides an aerosol "smoke" which is chemically simple, consisting essentially of oxides of carbon, air, water, and the aerosol which carries any desired flavorants or other desired volatile materials, and trace amounts of other materials. The aerosol "smoke" has no significant mutagenic activity as measured by the Ames Test. In addition, the article may be made virtually ashless so that the user does not have to remove any ash during use.
One embodiment of the present smoking article comprises a short combustible carbonaceous fuel element; a short heat stable, preferably carbonaceous substrate bearing an aerosol forming substance, and a relatively long mouthend piece. The fuel element and the substrate are arranged in a heat exchange relationship, thereby causing aerosol formation without significant degradation of the aerosol former.
