Aerosol provision system

A non-combustible aerosol provision system comprising an aerosol provision device, an article having an aerosol generating material and a mouthpiece downstream of the aerosol generating material, wherein:

• the aerosol generating material provides an aerosol when heated by the aerosol provision device;
• and
• the mouthpiece comprises a capsule and a part of the mouthpiece in which the capsule is located reaches a temperature of between 58 and 70 degrees Centigrade during use of the system to generate the aerosol,
• wherein a pressure drop across the mouthpiece is less than about 40 mmH2O, and
• wherein ventilation is provided into the mouthpiece, and
• wherein the aerosol generating material comprises at least 5% by weight of an aerosol forming material, wherein the aerosol forming material comprises at least one selected from a group consisting of glycerine, glycerol, propylene glycol, a combination of glycerol and propylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, 1,3-butylene glycol, erythritol, meso-Erythritol, ethyl vanillate, ethyl laurate, a diethyl suberate, triethyl citrate, triacetin, a diacetin mixture, benzyl benzoate, benzyl phenyl acetate, tributyrin, lauryl acetate, lauric acid, myristic acid and propylene carbonate;
• wherein a largest cross sectional area of the capsule measured perpendicularly to the longitudinal axis of the mouthpiece is less than 28% of a cross sectional area of the body of material measured perpendicularly to the longitudinal axis of the mouthpiece.
