A smoking article, such as a cigarette, has a filter which incorporates a volatile smoke-modifying agent. The filter comprises zeolite granules impregnated with the volatile agent. A cavity-type of filter may contain between 10 and 200 mg of mentholated zeolite granules. The loading level of a menthol on the zeolite granules may be within a range of from 3 to 60 mg/g. Cellulose-acetate plugs may be provided at the ends of the filter cavity.
