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.
