An approximately full smoking article, e.g. B. a cigarette, in front of the constantly circulating, in the vicinity of the outside designed as a mouthpiece feeder extending an additional circumference through the cylinder 6, narrower To arrange the filter distanced in the tobacco rod with the formation of an annular passage 8 or a ring of narrow through an annular space filled with tobacco, allows a free flow of smoke during the so that during each puff a TeU of smoke stream 65 is drawn. A bigger one, going through the cylinder 6 through the additional filter and the other part of the extending axial passage 9, it flows axially past it, with both elongated radial openings 10, 11 subsequently flowing through the mouthpiece together with a wide stream; Ren approximately annular passage 12 connected to the
