Abstract: A delivery system including an aerosol-generating material, an aerosolizable material and an aerosol-modifying agent release component. The aerosol-generating material can include tobacco material. The aerosolizable material can include an inorganic material, a binder and an aerosol-former material. The aerosol-modifying agent release component can include an aerosol modifying agent.

Abstract: A tobacco composition including tobacco material and an aerosol former material. The tobacco material includes a leaf tobacco having sugars and nicotine in a weight ratio of between about 8:1 and about 20:1, wherein said leaf tobacco having sugars and nicotine in a weight ratio of between about 8:1 and about 20:1 is present in the tobacco material in an amount of at least 5% by weight of the tobacco material.

Abstract: A mouthpiece for an article for use in an aerosol provision system and an article for use in an aerosol provision system. A mouthpiece for an article for use in an combustible aerosol provision system includes a body of material at a mouth end of the mouthpiece. The body has a longitudinal axis and a cross sectional area measured perpendicular to the longitudinal axis and comprises fibrous material. The total denier of fibrous material per cross sectional mm2 of the body is less than about 720 grams/9000 m. The pressure drop across the length of the body is from 1.05 to 1.70 mm water per mm length of the body.

Abstract: A mouthpiece for an article for use in an aerosol provision system is described. The mouthpiece includes a section having a longitudinal axis and a cross sectional area measured perpendicular to the longitudinal axis. The section includes fibrous material having a denier per filament of between 13.1 and 14.9 g/9000 m.

Abstract: A mouthpiece for an article for use in an aerosol provision system. The mouthpiece can have a section having a longitudinal axis and a cross sectional area measured perpendicularly to the longitudinal axis, the section including a fibrous material having a total denier of between 300 and 500 grams/9000 m per mm2 of said cross sectional area. The section can additionally or alternatively have a fibrous material having a total denier of between 200 and 600 grams/9000 m per mm2 of said cross sectional area and at least one of more than 75 fibers per mm2 of said cross sectional area and a denier per filament of less than 9.0 grams/9000 m. A section of fibrous material can have a denier per filament of less than 5.0 grams/9000 m and a capsule embedded within the fibrous material, wherein the section has an outer circumference of less than 21 mm.

Abstract: A smoking article is described in which the smoking article comprises tobacco material wrapped in a paper wrapper to form a tobacco rod, and wherein the paper wrapper has a diffusivity of between about 0.1 cm/s and 0.5 cm/s and a permeability of less than about 15 CU, and a method of manufacturing the smoking article is described.
