Abstract

An aerosol provision device 702 is disclosed comprising a mouthpiece 726 and one or more first aerosol generating regions 730 located a first distance d1 from the mouthpiece 726. One or more second aerosol generating regions 731 are located a second distance d2 from the mouthpiece 726, wherein d2>d1. The aerosol provision device 702 further comprises one or more first aerosol transmission channels 710 arranged to communicate aerosol generated from the one or more first aerosol generating regions 730 to the mouthpiece 726, wherein the one or more first aerosol transmission channels 710 have a first cross-sectional or other profile and wherein one or more second aerosol transmission channels 711 are arranged to communicate aerosol generated from the one or more second aerosol generating regions 731 to the mouthpiece 726, wherein the one or more second aerosol transmission channels 711 have a second cross-sectional or other profile, and wherein the second cross-sectional or other profile is different from the first cross-sectional or other profile.

An aerosol provision device as claimed in  claim 1 , wherein the cross sectional or other profiles of the one or more first aerosol transmission channels and the one or more second aerosol transmission channels are configured such that the amount of aerosol provided from the one or more first aerosol generating regions and the one or more second aerosol generating regions are substantially equal. 
     
     
         5 . An aerosol provision device as claimed in  claim 1 , wherein the second cross-sectional or other profile is larger than the first cross-sectional or other profile. 
     
     
         6 . An aerosol provision device as claimed in  claim 1 , wherein the cross sectional or other profiles of the one or more first aerosol transmission channels and the one or more second aerosol transmission channels are configured such that the speed of delivery of aerosol from the one or more first aerosol generating regions and the one or more second aerosol generating regions to the mouthpiece are substantially equal. 
     
     
         7 . An aerosol provision device as claimed in  claim 1 , wherein the aerosol provision device comprises a central aerosol transmission channel, wherein the one or more first aerosol transmission channels and the one or more second aerosol transmission channels are formed within the central aerosol transmission channel. 
     
     
         8 . An aerosol provision device as claimed in  claim 7 , wherein the central aerosol transmission channel has a cross-sectional or other profile which tapers. 
     
     
         9 . An aerosol provision device as claimed in  claim 1 , wherein the one or more first aerosol transmission channels are separate from the one or more second aerosol transmission channels. 
     
     
         10 . An aerosol provision device as claimed in  claim 1 , further comprising one or more heating elements for heating the one or more aerosol generating regions. 
     
     
         11 . An aerosol provision device as claimed in  claim 10 , wherein the one or more heating elements comprise one or more resistive or inductive heating elements. 
     
     
         12 . An aerosol provision system comprising:
 an aerosol provision device as claimed in  claim 1 ; and   an aerosol generating article comprising portions of aerosol generating material.   
     
     
         13 . An aerosol generating article comprising:
