A method of reducing the quantity of a first constituent in aerosol generating material using an aerosol generating device configured to deliver inhalable aerosol to a user is disclosed. The method comprises performing a first aerosolization process on a portion of the aerosol generating material comprising the first constituent to generate an aerosol for user inhalation, and performing a second aerosolization process on at least the portion of the aerosol generating material until the at least the portion of the aerosol generating material is substantially free of the first constituent. Also provided is an aerosol provision device and an aerosol provision system.

An aerosol provision device for generating aerosol from an aerosol generating material is disclosed. The device comprises at least one heating element arranged so as to be adjacent aerosol generating material when the aerosol generating material is present in the aerosol provision device. The heating element has a surface arranged to increase in temperature when supplied with energy and the surface defines an area of no greater than 130 mm.sup.2 or 145 mm.sup.2. Also described is an aerosol provision system, and a method for generating aerosol.
