A smoking article in the form of a filter cigarette can have adjustable air dilution provided by alignment of perforations in the paper wrap of the tobacco rod, a band circumscribing the rod, and the tipping paper. The band is attached to the rod and the tipping is movable relative thereto. Perforations extending about a portion of the circumferential distance around the smoking article allow the user to adjust the setting to low or high air dilution.
