Open the CIPO recordAbstract From the Canadian patent
A method and an apparatus for regenerating tobacco smoke by separation of the gaseous constituents from the condensed constituents. The gaseous constituents which contain many of the harmful substances in tobacco smoke are eliminated and the residue of the condensed constituents is collected. For purposes of smoking the condensate, an aerosol is produced from this condensate for inhalation by the smoker. Heating is an effective means to produce the aerosol and since the heating occurs at low temperature, there is no re-combustion of tobacco and the attendant production of harmful constituents.
