Summary:PROBLEM TO BE SOLVED: To provide a cigarette having a cigarette filter incorporating a form of carbon capable of efficiently and effectively adsorbing gas phase components present in mainstream cigarette tobacco smoke with a lesser impact on the perceived taste of the cigarette when smoked.SOLUTION: A smoking article such as a cigarette (10) comprises a tobacco rod (12) and a filter component (14) having a cavity (22) filled with spherical beaded carbon (24). As mainstream tobacco smoke is drawn through the filter component (14), targeted gas phase smoke constituents are removed as the smoke passes through the carbon (24). During the filter manufacturing process the spherical beaded carbon (24) flows like a liquid and substantially completely fills the cavity (22). Point-to-point contact between the spherical beads (24) together with substantially complete filling of the cavity (22) produces minimal channeling of gas phase as well as maximum contact between the gas phase and the carbon surface of the spherical beads (24) during smoking.
