A smoking article is adapted to cut down or eliminate the emission of sidestream smoke particulates to the ambient atmosphere, by having its rod (2) of smokable material surrounded by a wall (7) spaced from the rod (2). The wall may be that of a closed container (16). The wall will preferably include layer(s) containing adsorbents, heat absorbers and/or catalysts. A filtered end (3) of the smokable material rod (2) is accessible from outside the container at one end for smoking. At the other end an end cap (11) is removable to allow for lighting the smokable material rod (2).
