Abstract: An aerosol-generating system is provided, including an aerosol-generating article and an aerosol-generating device. The aerosol-generating article includes a first compartment having a first one of a volatile delivery enhancing compound source and a medicament source; and a second compartment having a second one of the volatile delivery enhancing compound source and the medicament source. The aerosol-generating device includes a cavity configured to receive the first compartment and the second compartment; and an external heater positioned about a perimeter of the cavity. The aerosol-generating device is configured to heat the first compartment and the second compartment so that the first compartment has a lower temperature than the second compartment.

Abstract: A smoking article having a proximal end and a distal end is provided, including a combustible heat source disposed at the distal end; an aerosol-forming substrate downstream of the combustible heat source; a mouthpiece downstream of the aerosol-forming substrate and disposed at the proximal end; and a tubular element slideable from a first position towards the distal end to a second position. In the second position, the slideable element at least partially extends over the combustible heat source and is configured to reduce the air supply to the combustible heat source. The tubular element is configured to modify a heat output of the combustible heat source, and to control a resistance-to-draw of the smoking article by selectively covering air inlets.
