Abstract: There is described an aerosol provision article for use with an aerosol provision device for generating an inhalable medium including an aerosol. The aerosol provision article includes a first chamber for containing a first substance that is heatable to generate an aerosol; a conduit that extends through the first chamber, the conduit having an inlet through which aerosol generated from the first substance can enter the conduit and an outlet through which the aerosol can exit the conduit and a second chamber for receiving a second substance, wherein the second chamber is downstream of the outlet of the conduit. The article is arranged such that in use aerosol exiting the outlet of the conduit passes through the second substance received in the second chamber, and wherein the cross-sectional area of the conduit increases at or towards the outlet.

Abstract: Apparatus and methods for generating an inhalable medium are disclosed. An apparatus includes a container for holding a liquid, a heater for volatilizing liquid held in the container to generate a flow of at least one of a vapor and an aerosol in use, and a receptacle for receiving material. The receptacle is located adjacent to the heater such that in use, material received in the receptacle is heated by the heater. One or more constituents of material received in the receptacle in use are mixed with the flow of at least one of a vapor and an aerosol in use to produce the inhalable medium.

Abstract: An article is provided for use with an apparatus for heating smokable material to volatilize at least one component of the smokable material. The article has a carrier and smokable material arranged on the carrier. The smokable material has a first layer of smokable material and a second layer of smokable material. The first layer of smokable material is located between the carrier and the second layer of smokable material. The smokable material of the first layer of smokable material has a form or chemical composition that differs from the form or chemical composition, respectively, of the smokable material of the second layer of smokable material.

Abstract: A vapor provision system configured to selectively generate differently-flavored vapors for inhalation by a user and to make use of this ability to provide user feedback. The system includes a first vapor precursor material having a first flavor and a second vapor precursor material having a second, different, flavor one or more vaporizers arranged to generate vapor from a selectable ratio of the first and second vapor precursor materials to provide a vapor with a selectable flavor for normal use; and control circuitry configured to determine if a user notification condition arises for the vapor provision system, such as a low battery warning, and in response to determining a user notification condition has arisen, to control the at least one vaporizer to generate a vapor using a modified ratio of the first and second vapor precursor materials to provide a vapor with a different flavor by way of an indication that a user notification condition has arisen.

Abstract: Heat not burn products comprising an encapsulated aerosol generating agent, the encapsulation having the effect of controlling the release of the agent during use of the heat not burn product. The encapsulation will control the timing of the release of the aerosol generating agent during the use of the heat not burn product, to allow greater control of the puff yield. In the case of some aerosol generating agents, the encapsulation may also increase the stability of the agent and/or prevent its migration within the product.
