Aerosol provision systems

An inhaler component for generating vapor from a vapor precursor material for an electronic vapor provision system comprising the inhaler component and a base unit, wherein the base unit and the inhaler component may be selectively coupled and uncoupled;

• wherein the inhaler component is associated with an identifier that is provided to the base unit, wherein the inhaler component is configured to receive an amount of consumable from the base unit when the inhaler component is coupled to the base unit and to generate vapor for user inhalation when the inhaler component is uncoupled from the base unit, wherein the indication the consumable has been provided to the inhaler component comprises an indication of the amount of the consumable that has been provided to the inhaler component by the base unit.
