Abstract
A cigarette having a multi-component filter wherein an upstream sorbent removes at least one constituent from mainstream tobacco smoke passing through the filter and a downstream flavor segment compensates for taste lost to the sorbent. The flavor component includes cellulosic flavor bearing granules which release volatile flavor constituents into the mainstream smoke under ambient conditions. The cellulosic granules include microcrystalline cellulose or other cellulosic material which can be formed into a paste with the flavor additive, extruded and spheronized to form the flavor granules.
