ABSTRACT:
A filter cigarette is provided which comprises a tobacco rod which includes a charge of tobacco wrapped in cigarette paper, an integral, axially aligned wrapped cylindrical filter plug, and tipping paper. The filter plug is divided into first and second segments with the first segment being rotatable with respect to the second segment. Rotation of the first segment with respect to the second segment causes axial movement of the first segment which serves to vary the air dilution value of the cigarette by uncovering a permeable region in the plug wrapping.
