Abstract: A smoking article comprises a tobacco rod and a filter connected to the tobacco rod. The filter comprises a first filter segment and a hollow tube segment downstream of the first filter segment. The hollow tube segment defines a cavity at the mouth end of the filter providing an unrestricted flow channel that extends from the downstream end of the first filter segment to the mouth end of the filter. The length of the hollow tube segment is at least about 25 percent of the overall filter length. Further, the smoking article comprises a ventilation zone comprising at least one circumferential row of perforations provided at a location around the first filter segment.
