    • A cigarette includes a rod comprising a wrapped tobacco column that is joined to an axially aligned filter by a band of air impermeable tipping paper. The filter end of the rod is inserted into a mouthpiece having an air impermeable outer surface that comprises a ventilation tube and a second filter, separated by a mixing chamber. The ventilation tube has an air permeable annular wall that defines a central axial passage through which the rod extends. In use, the end surface of the annular wall at the rod end of the ventilation tube, which extends radially outward around the rod, acts as a ventilation surface through which air is drawn into the mixing chamber, where it mixes with mainstream smoke from the burning tobacco rod. The air/smoke mixture is drawn through the second filter into the consumer's mouth.
