Abstract

A tobacco composition comprising a tobacco component and an aerosol forming material, wherein the tobacco component comprises leaf tobacco material in an amount of between about 10% and about 90% by weight of the tobacco component and wherein the leaf tobacco material has a nicotine content of greater than 1.5% by weight of the leaf tobacco material and a method of making the tobacco composition. Also, an article comprising the tobacco composition for use in an aerosol provision system and a system comprising a device arranged to heat the tobacco composition and generate an aerosol from the tobacco composition.

         10 . A tobacco composition as claimed in  claim 1 , wherein the aerosol forming material is selected from the group consisting of glycerol, sorbitol, propylene glycol, triethylene glycol, lactic acid, diacetin, triacetin, triethylene glycol diacetate, triethyl citrate, ethyl myristate, isopropyl myristate, methyl stearate, dimethyl dodecanedioate, dimethyl tetradecanedioate, and mixtures thereof. 
     
     
         11 . A tobacco composition as claimed in  claim 10 , wherein the aerosol forming material comprises glycerol. 
     
     
         12 . A tobacco composition as claimed in  claim 1 , wherein the tobacco component comprises paper reconstituted tobacco material. 
     
     
         13 . A tobacco composition as claimed in  claim 12 , wherein the paper reconstituted tobacco material comprises the aerosol forming material in an amount of between about 10% and about 20% by weight of the reconstituted tobacco material. 
     
     
         14 . A tobacco composition as claimed in  claim 12 , wherein the tobacco component comprises paper reconstituted tobacco material in an amount of between about 50% and about 90% by weight of the tobacco component. 
     
     
         15 . A tobacco composition as claimed in  claim 1 , wherein the tobacco component comprises tobacco material selected from the group consisting of extruded tobacco, bandcast tobacco, and mixtures thereof. 
     
     
         16 . A tobacco composition as claimed in  claim 1 , wherein the tobacco composition comprises a filler. 
     
     
         17 . A tobacco composition as claimed in  claim 16 , wherein the tobacco composition comprises between about 5% and about 10% of the filler. 
     
     
         18 . A tobacco composition as claimed in  claim 1 , wherein the leaf tobacco material and/or the paper reconstituted tobacco material comprises a width of between about 0.5 mm and about 2 mm. 
     
     
         19 . A method of manufacturing the tobacco composition as claimed in  claim 1 , the method comprising applying said aerosol forming material to said leaf tobacco material.
