Aerosol provision systems for generating an aerosol for user inhalation are disclosed. The aerosol delivery system includes a replaceable part 24 and a reusable part 22 comprising a substrate 110 that provides an aerosol generating material for generating an aerosol for inhalation by a user, the reusable part comprising: an interface 26 configured to operatively engage the possible component 24, and an interface 26 configured at least partially within the housing to provide passage of air drawn in by user inhalation to receive an aerosol generated from the aerosol generating material. a housing 32 comprising an air channel 50, a detector 92 configured to detect passage of air drawn through the air channel; at least one aerosol-generating element 112 disposed against the interface 26 and configured, in use, to generate an aerosol from the aerosol-generating material, and a signal from a detector 92 indicative of an amount of air inhaled by the user. a control circuit 38 configured to receive and control the at least one aerosol-generating element 112 to selectively generate an aerosol from different regions of the aerosol-generating material in response to an amount of air drawn through the air channel 50 . ) is included. |
