Abstract
A method and apparatus for regenerating tobacco smoke such that certain of the constituents may be smoked upon aerosolization thereof. The method and apparatus relies upon generating smoke from tobacco leaves or other grown plant substances and passing the smoke through a solvent, such as water. Certain of the fluidized components and certain of the gaseous components in the stream of tobacco smoke may then be captured in and preferably dissolved in the solvent. The dissolved or suspended smoke components may then be formed into an aerosol for inhalation by a user. By dissolving selected components in the solvent, many of the harmful gaseous and fluidizided constituents of a smoke stream are eliminated. Moreover, an aerosol is generated such that the particle sizes of the aerosol are sufficiently large that they are predominantly deposited in the upper respiratory tract. In this way, the smoker receives the sensations to which the smoker is normally accustomed from tobacco smoke without many of the harmful side effects of tobacco smoke.
