Smoking article
First Claim
1. A cigarette-type smoking article comprising:
- (a) a carbonaceous fuel element;
(b) a physically separate aerosol generating means including a volatile substance, the aerosol generating means being longitudinally adjacent to the fuel element; and
(c) a mouthend piece;
the fuel element and the aerosol generating means being arranged in a conductive heat exchange relationship by contact between the aerosol generating means and a part of the fuel element such that the aerosol generating means receives conductive heat transfer substantially throughout the time of burning of the fuel element.

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 relationshp, thereby causing aerosol formation without significant degradation of the aerosol former.
