A cartridge for an aerosol provision system comprising the cartridge and a control unit. The cartridge comprises: an air channel extending from an air inlet for the cartridge to an outlet via an aerosol generation region; a heating element for heating aerosolizable material, such as liquid, from a reservoir to generate aerosol in the aerosol generation region; and a valve located in the air channel upstream of the aerosol generating region. The cartridge is configured such that air passing through the air channel is configured to pass from the air inlet, past the air valve, into the aerosol generating region, and then out from the aerosol outlet. |
