An aerosol provision device for use with an aerosol generating article including aerosol generating material having one or more aerosol generating components arranged to aerosolize different portions of the aerosol generating material and control circuitry for supplying power to the one or more aerosol generating components, the control circuitry is configured to perform an aerosolization process on a first portion of the aerosol generating material on at least two separate occasions.

An aerosol provision device and related methods and means for generating aerosol from an article including portions of aerosol generating material. The device includes a receptacle for receiving the article including, portions of aerosol generating material, an outlet fluidly coupled to the receptacle, at least one aerosol generating component configured to perform an aerosolization process on one or more of the portions of aerosol generating material when the article is received in the receptacle and control circuitry for controlling the aerosol generating component. The control circuitry is configured to cause the at least one aerosol generating component to generate an amount of aerosol from a respective portion of aerosol generating material based on the distance of the respective portion of aerosol generating material from the outlet.
