Definitions

  • the present disclosure relates to an article/consumable for use in a smoking substitute system and particularly, although not exclusively, to a heat-not-burn (HNB) consumable.
  • HNB heat-not-burn
  • cannabis also known as marijuana or hashish
  • cannabis is widely known for both medicinal and recreational purposes.
  • recreational use of cannabis has been legalized, or is officially tolerated.
  • Cannabis comprises numerous (phyto-)cannabinoids some of which can act on human cannabinoid receptors (CB 1 and CB 2 ) to affect physiological processes such as appetite, mood, stress response and muscular/joint pain relief.
  • CB 1 and CB 2 human cannabinoid receptors
  • Ingestion of cannabis is typically through smoking (either alone or mixed with tobacco) and is considered to expose a smoker to potentially harmful substances. It is generally thought that a significant amount of the potentially harmful substances are generated through the heat caused by the burning and/or combustion of the cannabis (and tobacco) and the constituents of the burnt cannabis (and tobacco) in the smoke itself.
  • junctions are typically rolled by hand by the user and comprise a roughly cylindrical wad of dried cannabis leaves/buds/flowers which is surrounded by a paper wrapper.
  • a filter may or may not be included, axially aligned in an abutting relationship with the wrapped cannabis wad.
  • a conventional cannabis smoking article of this type is used by lighting the end opposite to the filter, and burning the cannabis wad. The smoker receives mainstream smoke into their mouth by drawing on the filter end of the article.
  • Smoking substitute systems for cannabis include heat-not-burn (HNB) systems in which a heater heats ground, chopped or loose leaf cannabis plant material contained within a sealed container pod or capsule to produce an aerosol (also referred to as a "vapour") that is drawn into the lungs through the mouth (inhaled) and then exhaled.
  • HNB heat-not-burn
  • aerosol also referred to as a "vapour”
  • the inhaled aerosol typically bears cannabinoids without, or with fewer of, the odour and health risks associated with traditional cannabis smoking.
  • the present disclosure relates to an aerosol-forming article e.g. a consumable for use in a smoking substitute system and particularly, although not exclusively, to a heat-not-burn (HNB) consumable, wherein the article/consumable comprises a substrate comprising a cannabinoid-containing plant material.
  • HNB heat-not-burn
  • an aerosol-forming article comprising an aerosol-forming substrate and one or more of a hollow bore element, a filter element, a spacer element and/or an aerosol-cooling element downstream of the substrate wherein the substrate comprises a cannabinoid-containing plant material.

  • the aerosol-forming substrate is capable of being heated to release at least one cannabinoid compound (e.g. a mixture of cannabinoid compounds) that can form an aerosol.
  • cannabinoid compound e.g. a mixture of cannabinoid compounds
  • Cannabinoid compounds include phyto-cannabinoids which include:
  • the cannabinoid compound is selected from at least one of cannabidiol (CBD) and its derivatives/homologues e.g. cannabiodiol-C 5 (CBD-C 5 ), cannabidiol-C 4 (CBD-C 4 ), cannabidiol mono(m)ethyl ether (CBDM-C 5 ), cannabidivarin (CBDV-C 3 ), cannabidiorcol (CBD-C 1 ), cannabidiolic acid (CBDA-C 5 ), cannabidivarinic acid (CBDVA-C 3 ).

  • HNB heat-not-burn
  • the aerosol-forming substrate may be located at an upstream axial end of the article/consumable.
  • upstream and downstream are intended to refer to the flow direction of the vapour/aerosol i.e. with the downstream end of the article/consumable being the mouth end or outlet where the aerosol exits the article/consumable for inhalation by the user.
  • the upstream end of the article/consumable is the opposing end to the downstream end.
  • the aerosol-forming substrate may be at least partly circumscribed by a wrapping layer e.g. a paper wrapping layer.
  • the aerosol-forming substrate may be formed in a substantially cylindrical shape such that the article/consumable resembles a conventional cigarette. It may have a diameter of between 5 and 10 mm e.g. between 6 and 9 mm or 6 and 8 mm e.g. around 7 mm. It may have an axial length of between 10 and 15 mm e.g. between 11 and 14 mm such as around 12 or 13 mm.
  • the hollow bore element (where present) comprises a hollow bore which extends the axial length of the hollow bore element.

  • the upstream hollow bore element may be axially adjacent i.e. immediately downstream of the substrate.
  • the or each hollow bore element may have an axial bore i.e. aligned with the axis of the hollow bore element.
  • the terminal hollow bore element (where present) may have a hollow bore which is off-set from the axial centre of the terminal hollow bore element.
  • the terminal hollow bore element By providing an axially off-set hollow bore in the terminal hollow bore element, the temperature of the vapour entering the user's mouth will be reduced whilst the visible vapour (total particulate matter) will be maintained.
  • the vapour/aerosol upon reaching the terminal hollow bore element, it will meet the axial upstream end of the terminal hollow bore element and will be forced to take a convoluted path through the off-set bore. This convoluted path will help mix and cool the vapour/aerosol prior to inhalation.
  • the terminal hollow bore element may comprise only the single axially off-set hollow bore and no other bores i.e. the terminal hollow bore element is preferably solid other than for the single off-set hollow bore.
  • axially off-set means that the axial centre of the hollow bore is not aligned with the axial centre of the terminal hollow bore element.
  • the axial centre of the terminal hollow bore element may, however, be within the off-set bore.
  • the or each hollow bore may have a bore diameter of between 1 and 5 mm, e.g. between 2 and 4 mm or between 2 and 3 mm.
  • the upstream hollow bore element preferably has a larger bore diameter than the terminal hollow bore element.

  • the upstream hollow bore element may have a bore diameter of 3 or 3.5 mm whilst the terminal hollow bore element may have a bore diameter of around 2mm.
  • a greater mixing effect is achieved within the terminal hollow bore element as all of the components of the vapour/aerosol are forced to co-locate within the more restricted hollow bore.
  • the terminal hollow bore element may have an increased density or increased hardness than the upstream hollow bore element i.e. the upstream hollow bore element may have an increased porosity than the terminal hollow bore element. This is to increase the flow and mixing of the vapour/aerosol within the hollow bore of the terminal hollow bore element.
  • the increased hardness/reduced porosity of the terminal hollow bore element forces the aerosol/vapour to enter the axial bore through the terminal hollow bore element (since the passage through the body of the terminal hollow bore element is impeded) and this forces the components within the vapour/aerosol to co-locate within the bore thus increasing mixing.
  • Hardness can be measured using a standard densitometer such as a Borgwaldt densitometer DD60A. During such measurement, the diameter of the hollow bore element is measured and then a crushing load (e.g. 3kg) is applied and the remaining diameter (parallel to the applied force) measured after a given time. A percentage hardness is calculated as the remaining diameter divided by the initial diameter x100.

  • the upstream hollow bore/filter element may have an axial length of 10 mm or less and the terminal hollow bore/filter element has an axial length greater than 10mm e.g. around 12mm.
  • Providing a shorter upstream hollow bore/filter element results in a greater concentration of the volatile compound (e.g. CBD) at the terminal hollow bore/filter element because there is less condensation of the volatile compound on the upstream hollow bore/filter element.
