<p>A cigarette (10) comprises a filter (14) and a tobacco rod (12). The filter includes a capsule (16) having opposite end walls with flavored adsorbent particles in the enclosure of the capsule. The end walls are perforated so that mainstream tobacco smoke passes through the capsule during the smoking process to thereby modify the characteristics of the smoke. Overall the capsule enables more exact filling of adsorbent particles and more control of flavor per cigarette.</p>
