         14 . A delivery system as claimed in  claim 2 , wherein the filamentary tow comprises a denier per filament in the range 5 to 12. 
     
     
         15 . A delivery system as claimed in  claim 1 , wherein the aerosol modifying agent release component is a wrapper comprising the aerosol modifying agent. 
     
     
         16 . A delivery system as claimed in  claim 1 , wherein the aerosolizable material comprises the aerosol-former material in an amount of between about 10% and about 20% by weight of the aerosolizable material. 
     
     
         17 . A delivery system as claimed in  claim 1 , wherein the aerosol-generating material comprises the aerosolizable material an amount of between about 10% and about 90% by weight of the aerosol-generating material. 
     
     
         18 . A delivery system as claimed in  claim 1 , wherein the aerosolizable material comprises the inorganic material in an amount of at least about 10% by weight of the aerosolizable material. 
     
     
         19 . A delivery system as claimed in  claim 1 , wherein the aerosolizable material comprises the binder in an amount of at least about 1% by weight of the aerosolizable material. 
     
     
         20 .
