ABSTRACT:
A variable dilution filter cigarette is provided which includes a substantially cylindrical tobacco rod, an axially aligned, substantially cylindrical filter plug wrapped in a substantially air-permeable plug wrap, and a substantially air-permeable first layer of tipping paper which joins the filter plug to the tobacco rod. Circumscribing the first layer of tipping paper is a second layer of substantially air-impermeable tipping paper. The second layer has a circumferentially extending row of closely spaced perforations intermediate its two ends which divides it into a mouth-end sleeve attached to the first layer at the mouth end of the cigarette and a second rod-end sleeve detachable from the mouth-end sleeve.
