Summary:A cigarette includes a filter element including a carbon-containing paper or a paper containing molecular sieves. The paper contacts the filter material, such as cellulose acetate tow, within the filter element, either by circumscribing the filter material or by being gathered with non-carbon-containing filter material. The paper is useful as a plug wrap for a filter element. In several embodiments, longitudinal grooves are provided on the periphery of the filter element.
