Abstract: In one aspect, apparatus is provided for generating an inhalable medium. The apparatus has a container for holding a liquid and a heater for volatilizing liquid held in the container. The apparatus further has a chamber for receiving a material. The apparatus has an outlet. In use liquid volatilized by the heater passes, in the form of at least one of a vapor and an aerosol, through material received in the chamber to thereby entrain one or more constituents from the material to produce the inhalable medium which passes out of the outlet.

Abstract: Embodiments described herein include a method of making a tobacco extract comprising; (a) contacting tobacco with an extraction solvent such that tobacco components are extracted from the tobacco into the solvent, wherein the extraction solvent comprises a supercritical fluid; (b) separating the residual tobacco solids from the supercritical extraction solvent containing tobacco components; (c) exposing the extraction solvent containing tobacco components to conditions in a vessel at which the extraction solvent is subcritical, thereby releasing the tobacco components from the extraction solvent; and then (d) washing the vessel with an entrapment solvent which dissolves the tobacco components, wherein the entrapment solvent comprises an aerosol generating agent.

Abstract: Embodiments described herein include a method of making a tobacco extract comprising; (a) contacting tobacco with an extraction solvent at a first temperature and first pressure which are selected such that the extraction solvent is supercritical, such that tobacco flavor and/or aroma components are extracted from the tobacco into the solvent; (b) separating the residual tobacco solids from the supercritical extraction solvent containing tobacco components; (c) exposing the extraction solvent containing tobacco components to conditions in a vessel at which the extraction solvent is subcritical, thereby releasing the tobacco components from the extraction solvent, (d) contacting the residual tobacco solids with an extraction solvent at a second temperature and second pressure which are selected such that the extraction solvent is supercritical, such that nicotine are extracted from the tobacco into the extraction solvent; and wherein the second temperature and/or second pressure is higher than the respective f

Abstract: Embodiments described herein include a cartridge for use with an apparatus for generating an inhalable medium, the cartridge comprising: a first chamber containing a liquid, the liquid comprising a liquid tobacco extract; a second chamber configured to receive a solid flavor material; and the cartridge being arranged such that in use, the liquid is volatilized to form a vapor or an aerosol, and the vapor or aerosol combines with one or more components of the solid flavor material received in the second chamber to form an inhalable medium, the inhalable medium comprising one or more constituents of the solid flavor material entrained in the vapor or aerosol.
