A filter cigarette is provided in which the smoker can select varying levels of one or more flavorants to be added to the smoke stream. A rotatable filter segment having several smoke flow paths, each containing a different flavorant material, cooperates with a baffle to select one or more paths through which the smoke stream will travel.
