Abstract A smoking article having a tobacco rod, which is adapted to produce mainstream smoke, and a filter attached to said tobacco rod. A permeable wrapping paper circumscribes the tobacco rod and the filter. The filter has an upstream end portion and a downstream end portion, and includes a flow restricting segment of smoke impermeable material, which includes at least one open flow passage therethrough to deliver mainstream smoke, and a cavity downstream of the flow restricting segment. The smoking article also includes at least one ventilation zone upstream of the flow restricting segment.
