Definitions

  • AEROSOL-GENERATING ARTICLE COMPRISING A PLURALITY OF PORTIONS OF AEROSOL-GENERATING SUBSTRATE
  • an aerosol is generated by the transfer of heat from a heat source to a physically separate aerosol-generating substrate.
  • volatile compounds are released from the aerosol-generating substrate by heat transfer from the heat source to the aerosol-generating substrate and are entrained in air drawn through the aerosolgenerating article. As the released compounds cool, they condense to form an aerosol that is inhaled by the user.
