Abstract
A cigarette includes a rod of smoking material, such as tobacco, to which is attached a mouthpiece that is substantially impervious to air and smoke except for an unfiltered axial bore or flow passage which extends through the mouthpiece. Unfiltered smoke flows from the rod to the interface between the rod and mouthpiece where it is substantially diluted with air and passes through the flow passage for delivery as unfiltered, air diluted smoke. The air dilution reduces the gas phase components of the unfiltered smoke thereby providing a smoother, better tasting cigarette.
