Aerosol generating material for inclusion in an aerosol provision system, such as an apparatus for heating aerosol generating material to volatize at least one component thereof, the aerosol generating material including an active substance and a volatile component incorporated by infusion. The invention also relates to methods for preparing such compositions and apparatus including such materials.

A wrapping material for a smoking article is formed from a web that includes extracted pieces of cannabis combined with web building fibers. The web has a basis weight of from about 20 gsm to about 80 gsm and a permeability of from about 10 Coresta to about 100 Coresta. The wrapping material has a natural cannabis smell and taste. The wrapping material is tobacco and nicotine free and can be used as a carrier for flavorings or aerosol delivery compositions.

Abnormally-shaped tobacco granules are provided. The tobacco granules comprise a tobacco granule body and a coating attached to the surface of the tobacco granule body. The coating contains an adhesive. The surface of the abnormally-shaped tobacco granule has one or more grooves and/or ridges, and/or, the abnormally-shaped tobacco granule has through holes therein. The surface grooves of the abnormally-shaped tobacco granules can serve as smoke channels after the tobacco granules are bonded, cured and shaped, so that the air permeability inside a total-granule tobacco product is greatly improved. The smoking resistance of cigarettes is reduced. The flammability of cigarettes is improved and the consumption of tobacco raw materials is reduced. A preparation method of the abnormally-shaped tobacco granules, a tobacco product comprising the abnormally-shaped tobacco granules, and a preparation method thereof are also provided.

The present invention relates to a method to produce a homogenized tobacco material for use in a heat-not-burn aerosol-generating article, comprising the steps of: —selecting a first target value for a first tobacco characteristic, said first tobacco characteristic being reducing sugars and the first target value being comprised between about (8) percent and about (18) percent in dry weight basis of a total amount of tobacco present within the homogenized tobacco material; —selecting a second target value of a second tobacco characteristic, wherein the second tobacco characteristic is one of total ammonia and total alkaloids; —blending graded tobacco types so as to form the tobacco blend, each graded tobacco type comprising a predetermined amount of the first and second tobacco characteristics, so that the first and second target values of said first and second tobacco characteristics are obtained in said blend within a predetermined tolerance range; —grinding said tobacco blend into a blended tobacco powder; —forming a slurry comprising the blended tobacco powder; and forming a web of homogenous tobacco web from the slurry.
