Abstract
The present invention provides improved cigarettes and other smoking articles in which the substrate is a cellulosic material, preferably paper or a paper-like material, e.g., tobacco paper. The substrate of the present invention is used to retain flavorants and the aerosol forming materials, which upon exposure to heated air passing through the aerosol generating means during smoking, are vaporized and delivered to the user as a smoke-like aerosol.
