A filter cigarette (1) comprises a rod of smokable material (2), and a mouth piece (3) attached to the rod (2), the mouth piece (3) comprising an element (5) rotatable with respect to the rest of the filter cigarette (1) about the longitudinal axis thereof such that a user can vary the ventilation of the filter cigarette (1) and a fixed element (6) that is fixed relative to the rod (2). There is also a strength indicator comprising a first scale (20) extending circumferentially around the periphery of the rotatable element (5), and a second scale (21) extending circumferentially around the fixed element (6), wherein each scale comprises a single marker formed by a line having its extremities intersecting a separation line (12) between the rotatable element (5) and the rest of the cigarette (1). |
