Abstract
A cigarette is provided having a variable length. A filter or mouthpiece slides within a sleeve attached to the cigarette, or a sleeve attached to the filter or mouthpiece slides over the cigarette. A single band is adhered to one element and a pair of bands is adhered to the other element. The single band is captive between the pair of bands so that the cigarette can be lengthened or shortened within the range allowed by the pair of bands, but the filter or mouthpiece cannot be removed from the cigarette. The variable length mechanism can be made to additionally provide variable dilution or variable flavorant.
