ABSTRACT:
A smoking article in the form of a filter cigarette can have adjustable air dilution capabilities. The filter element is movable toward and away from the tobacco rod along the longitudinal axis of the cigarette. Perforations in the tipping material of the cigarette expose the inner region of the cigarette and provide air dilution capabilities when the filter element and tobacco rod are in a spaced apart relationship. When the filter element and the tobacco rod are in a substantially abutting relationship, the perforations in the tipping material overlie a substantially air impermeable region of the tobacco rod thereby providing a low or non air diluted cigarette.
