Abstract: Described is an aerosol provision system for generating aerosol for user inhalation, wherein the system includes an aerosol generating article including an aerosolizable material, the aerosolizable material being a solid or a gel; and a control unit having a receptacle configured to receive the aerosol generating article, wherein the control unit is configured, in use, to generate aerosol from the aerosolizable material. The aerosol generating article includes a data storage unit configured to store an identifier identifying the aerosol generating article. The control unit is configured to receive the identifier from the data storage unit and, based on the received identifier, cause the control unit to perform an action.

Abstract: A control device for an electronic aerosol provision system is configured to receive a replaceable component to form an electronic aerosol provision system. The control device is further configured to receive an identifier from a replaceable component received by the control device; and to modify one or more characteristics (such as resistance to draw, RTD) of an airflow path through the electronic aerosol provision system dependent upon the received identifier.

Abstract: An apparatus for generating aerosol from an aerosolizable medium, the apparatus including a housing; and a chamber for receiving an article. The article includes an aerosolizable medium; and a marker arrangement including a first marker and a second marker. The apparatus includes a sensor arrangement configured to operate in a first mode and a second mode. In the first mode the sensor arrangement monitors non-continuously for the presence of the first marker. In the second mode the sensor arrangement is configured to read identification information from the second marker. The sensor arrangement operates in the second mode responsive to the detection of the presence of the first marker in the first mode.
