ABSTRACT:
An elongate smoking article for releasing an aerosol into the mouth of a smoker comprises, a fuel rod having a light-up end adapted to be lit by a smoker; a tube extending from the fuel rod to a mouth end of the article thereby defining a condensation chamber between the fuel rod and the mouth end of the article; ventilation means to permit the passage of ventilating air from the light-up end of the fuel rod to the condensation chamber, and a porous ceramic cylindrical element impregnated with an aerosol precursor surrounding the fuel rod and in intimate contact with at least a portion thereof. A permeable fire-proof sheath surrounds the ceramic element, the sheath being adapted to provide physical integrity of the whole assembly, to allow the inward diffusion of air to maintain and propagate combustion of the fuel rod and to allow outward diffusion of combustion products.
