1. A smoking device which comprises:

  • a combustion chamber capable of holding a combustible material;

    a mouthpiece;

    an air intake conduit connected to said mouthpiece, said conduit having an area contiguous to said combustion chamber but separated from it by a heat-conductive wall shaped and dimensioned to be capable of preventing smoke generated in said combustion chamber from entering said conduit and said mouthpiece;

    at least one aperture in said wall shaped and positioned to be capable of allowing passage of smoke between the combustion chamber and said conduit;

    means for opening and closing said aperture, such that when said aperture is open, smoke passes between the combustion chamber and the conduit;

    when said aperture is in an intermediate position, a mixture of smoke and air from said conduit passes to said mouthpiece; and

    when said aperture is closed, smoke is prevented from passing between the combustion chamber and the conduit; and

    volatile substances held within said area.
