AEROSOL PROVISION SYSTEM

An aerosol provision system comprising a reservoir for aerosolizable material, a wick for receiving aerosolizable material from the reservoir, and a vaporizer for vaporizing aerosolizable material in the wick. A structure from the aerosol provision system, in response to a temperature of the vaporizer or wick exceeding a predetermined temperature, is operable to change from a first configuration in which operation of the vaporizer is possible, to a second configuration in which operation of the vaporizer is prevented. This structure could be operable to reversibly change between the first configuration and the second configuration, and might be configured to short circuit the vaporizer in some cases. The structure might also be configured to disconnect a connection lead for delivering power to the in some cases.
