Abstract
Described is 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 including 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 and second flow pathways are each provided with a flow restriction member configured to vary the flow of air through the respective flow pathways based on the presence of an aerosol generating component in the respective aerosol generating areas in the device and/or a parameter associated with the respective aerosol generating component in the device.
