Abstract

Claims (9)

1. An aerosol-forming article comprising an aerosol-forming substrate formed of a plurality of longitudinally-aligned, elongate shreds of plant material;

wherein the aerosol-forming substrate comprises a plurality of first elongate shreds and a plurality of second elongate shreds, each first shred having longitudinal edges spaced by a first transverse width and each second shred having longitudinal edges spaced by a second transverse width, wherein the first transverse width is different to the second transverse width, wherein a region of the aerosol-forming substrate comprises a greater proportion of first shreds than second shreds, wherein there is a plurality of transverse bridge portions each extending between and joining two or more of the shreds.

2. An aerosol-forming article according to claim 1 wherein the aerosol-forming substrate comprises one or more cannabinoid compounds selected from cannabidiol (CBD) and its derivatives/homologues, cannabigerol (CBG) and its derivatives/homologues, cannabinol (CBN) and its derivatives/homologues, tetrahydrocannabinol (THC) and its derivatives/homologues, cannabicyclol (CBL) and its derivatives/homologues, cannabichromene (CBC) and its derivatives/homologues, cannabielsoin (CBE) and its derivatives/homologues, and cannabicitran (CBT) and its derivatives/homologues.

5. An aerosol-forming article according to claim 1 wherein the aerosol-forming article is a heat-not-burn (HNB) consumable.

6. An aerosol-forming article according to claim 1 wherein the region of the aerosol-forming substrate is a first region, and wherein the aerosol-forming substrate comprises a second region, the second region of the aerosol-forming substrate comprises a greater proportion of second shreds than of the first shreds and wherein the first region is disposed at a periphery of the aerosol-forming substrate and the second region is disposed at a central portion of the aerosol-forming substrate, which is spaced from the periphery of the aerosol-forming substrate.

7. An aerosol-forming article according to claim 1 wherein each transverse bridge portion spans ten or fewer immediately adjacent shreds of cannabinoid-containing plant material.

8. The aerosol-forming article of claim 1 wherein ratio of the greater of the first and second transverse width to the lesser of the first and second transverse width is between 1.5:1 and 3:1.
