Abstract
A smoking article including a cylindrical, open ended sleeve with a capsule concentrically located within the sleeve and cooperating with the sleeve to define an annular air flow passage therebetween. The capsule includes chemical reactants which exothermally react when mixed together. A porous substrate including an aerosol generating substance is located in the sleeve downstream of the capsule and annular air flow passage so that air flowing from the annular passage flows through the porous substrate. A filter is located at one end of the sleeve adjacent to and downstream of the porous substrate.
