ABSTRACT:
Cigarettes having low efficiency filters, rods of cut filler having a low packing density, and paper wraps having a high net permeabilities and low inherent permeabilities can yield good taste, low gas phase mainstream deliveries as well as low amounts of visible sidestream smoke. Typical cigarettes have relatively large amounts of volume expanded flue-cured tobacco materials as cut filler, paper wraps containing magnesium oxide and/or magnesium hydroxide, and relatively high levels of air dilution.
