1. An aerosol provision device for generating aerosol to be inhaled by a user from a plurality of discrete aerosol generating areas each containing an aerosol generating component, the aerosol provision device comprising:
a mouthpiece from which a user inhales generated aerosol during use;
a first flow pathway arranged to pass through a first aerosol generating area and fluidly connected to the mouthpiece; and
a second flow pathway arranged to pass through a second aerosol generating area and fluidly connected to the mouthpiece,
wherein the first flow pathway and the second flow pathway are each provided with a flow restriction member configured to vary a flow of air through the respective first flow pathway and the second flow pathway based on at least one of:
a presence of an aerosol generating component in the respective first aerosol generating area or the second aerosol generating area in the aerosol provision device, or
a parameter of the aerosol generating component in the respective first aerosol generating area or the second aerosol generating area in the aerosol provision device, wherein the parameter of the aerosol generating component is a quantity of aerosol precursor material of the aerosol generating component.
