Abstract: An aerosol delivery system including a first engagement mechanism, a first power supply, and a first vaporizer, wherein the first vaporizer is arranged to selectively receive power from the first power supply to generate a first aerosol from a first aerosol precursor material for user inhalation; and a second aerosol delivery device including a second engagement mechanism, a second power supply, and a second vaporizer, wherein the second vaporizer is arranged to selectively receive power from the second power supply to generate a second aerosol from a second aerosol precursor material for user inhalation; wherein the first engagement mechanism of the first aerosol delivery device and the second engagement mechanism of the second aerosol delivery device are arranged to releasably co-engage with one another to selectively couple the first aerosol delivery device to the second aerosol delivery device so the first aerosol delivery device and the second aerosol delivery device may be used together to deliver the f

Abstract: An aerosol provision system includes one or more receptacles each forming a respective central space, a base adapted to support the or each receptacle, the or each receptacle being removable from the base and at least a first airflow generator, operable to draw air through at least a first aerosol generator, wherein the base includes one or more outlets through which, in operation, aerosolized payload is directed to flow from the base into the central space of a respective receptacle and the or each receptacle comprises a first opening through which the user can inhale the aerosolized payload.

Abstract: An article for generating an inhalable medium using an irradiative light source. The article includes smokable material including at least two regions having a different composition from each other. The article is arranged such that the at least two regions of smokable material can be heated by light emitted by an irradiative light source of an apparatus with which the article can be engaged in use.

Abstract: A method of visualization between an electronic vapor provision system and a visualization device includes obtaining from the electronic vapor provision system notification that an inhalation on the electronic vapor provision system by a user has occurred, estimating a time of exhalation by the user responsive to the time of notification, and initiating a display of a computer graphic by the visualization device responsive to the estimated time of exhalation.

Abstract: There is provided an electronic vapor provision system comprising: a vaporizer for vaporizing liquid for inhalation by a user of the electronic vapor provision system; a power supply comprising a cell or battery for supplying power to the vaporizer; and a filter for filtering vaporized liquid prior to inhalation by the user of the electronic vapor provision system, wherein the filter can partially or completely remove from the vapor one or more aldehydes present in the vapor.
