Abstract
A method and an apparatus for regenerating tobacco smoke 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.

A method for producing a tobacco smoke condensate capable of being smoked, said method comprising:
- (a) heating tobacco to produce a tobacco smoke comprised of a mixture of fluidized components and gaseous components,
- (b) separating the gaseous components from the fluidized components,
- (c) expelling the separated gaseous components,
- (d) collecting the fluidized components as a condensate when the gaseous components have been expelled so that an aerosol may be formed therefrom, and
- (e) forming an aerosol with the fluidized components for smoking thereof.

- (a) tobacco receiving means for receiving a source of tobacco capable of being rapidly combusted and enabling combustion of the tobacco to produce tobacco smoke,
- (b) a chamber located in proximate relation to the tobacco receiving means for receiving and temporarily holding the tobacco smoke,
- (c) separating means operatively connected to said chamber to receive the tobacco smoke and enable a fractionation of certain constituents to thereby separate the gaseous constituents from the condensed constituents in the smoke, said separating means comprising a filter pad formed of a material and having a pore size such that a substantial portion of the condensed constituents will engage the filter pad material which causes a separation of the condensed constituents to enable collection thereof and which gaseous constituents will pass therethrough,
- (d) exhaust means operatively associated with said separating means to permit discharge of the gaseous constituents, and
- (e) container means operatively associated with said separating means for collecting the condensed constituents as a somewhat liquid condensate which is capable of being easily aerosolized for smoking upon aerosolization thereof.
A method for smoking an aerosol of condensed tobacco smoke constituents to provide the sensory effects of normal tobacco smoke without many of the harmful gaseous constituents therein, said method comprising:
- (a) disposing a container of condensed tobacco smoke constituents separated from tobacco smoke and locating the condensed constituents in a position where they may be contacted by a relatively inert gas from a source of a relatively inert gas,
- (b) contacting the condensed constituents with the relatively inert gas,
- (c) generating an aerosol of the condensed tobacco smoke constituents in the relatively inert gas and which aerosol will have an appearance and taste similar to that of normal tobacco smoke, and
- (d) permitting the aerosol of the condensed constituents to pass through a smoke delivery tube upon drawing by a smoker to allow receipt of the aerosol by the smoker.
The method of claim -4 further characterized in that the method comprises moving the container or the source of heat so that the source of heat is disposed in heating relationship to the container to aid in the generation of an aerosol.
A smoking apparatus to enable smoking of an aerosol of condensed tobacco smoke constituents without the harmful gaseous constituents normally carried in tobacco smoke, said apparatus comprising:
- (a) a housing,
- (b) a container of condensed tobacco smoke constituents located within said housing,
- (c) aerosol generating means to generate an aerosol of the condensed constituents which is similar to normal tobacco smoke in taste and appearance and which is capable of being inhaled by a smoker,
- (d) a tube associated with said housing to receive the generated aerosol, and
- (e) an outlet end associated with said tube and sized so that a smoker may impart a suction to the tube to receive the generated aerosol.
A smoking apparatus to enable smoking of an aerosol of condensed tobacco smoke constituents comprising:
- (a) an elongate tube,
- (b) a source of tobacco smoke condensate associated with said elongate tube, and
- (c) means to generate heat adjacent said source of condensate to generate an aerosol of the condensate without any appreciable combustion of the condensate and which does not contain any appreciable amount of the harmful gaseous constituents in normal tobacco smoke but is similar to normal tobacco smoke in taste and appearance and which is capable of being drawn through said elongate tube and inhaled by a smoker.
A method of enabling smoking of an aerosol of tobacco smoke condensate to receive the sensory effects of normal tobacco smoke without the harmful gaseous constituents normally present in tobacco smoke, said method comprising:
- (a) burning tobacco to produce a mixture of condensed constituents and gaseous constituents,

- (c) generating an aerosol of the condensed constituents in the smoking device without any appreciable combustion of the condensate to provide a smoke stream which does not contain any appreciable amount of the harmful gaseous constituents in normal tobacco smoke but which is similar in appearance and taste to normal tobacco smoke so that the aerosol can be inhaled by a user thereof with substantially reduced health risk.
A method for smoking an aerosol of condensed tobacco smoke constituents to provide the sensory effects of normal tobacco smoke without many of the harmful gaseous constituents wherein, said method comprising:
