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 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 and second flow pathways are each provided with an electrically operated 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. The device further comprises control circuitry configured to receive electrical signals obtained from the aerosol generating components indicating either the presence of an aerosol generating component in the device and / or a parameter of the aerosol generating component when the aerosol generating component is installed in the device and actuate the flow restriction members in response to the electrical signals. The device allows variation in the composition of the aerosol delivered to the user.
