Abstract

See full text

A smoking article comprises a smoking accessory and a cigarette. The smoking accessory includes a holder and a substantially air-impermeable sleeve which is coupled to a distal portion of the holder and is coaxial therewith. The cigarette is received in the smoking accessory such that a distal end of the cigarette is located substantially flush with a distal end of the sleeve. The cigarette includes a column of tobacco which is shorter than that used in conventional cigarettes, e.g., 20 mm in length or less. An air gap separates an outer surface of the cigarette from the sleeve, and plural openings are formed in the sleeve to supply air to the cigarette. In use, the sleeve restricts the flow of air to the cigarette, thereby slowing combustion and reducing sidestream smoke between puffs.
