Abstract
A ventilated mouthpiece adapted to be attached to a smoking article, such as a cigarette, includes a generally cylindrical core member of smoke and air impermeable material having a smoke inlet end and a mouth end. The smoke inlet end is to be placed in juxtaposition to one end of the tobacco column of the cigarette. The core member is formed with a plurality of smoke flow capillaries therethrough for delivering unfiltered smoke from the tobacco column to the mouth end of the core member, and at least one ventilation air flow channel which receives ambient ventilation air and delivers the ventilation air to the mouth end of the core member. The smoke outlets from the smoke flow capillaries at the mouth end of the core member are located at a further radial distance from the center of the core member than is the outlet from the at least one ventilation air flow channel.
