The cursor and the scale of the ventilation indicator are rotatable relative to one another about the longitudinal axis of the smoking article, one of the cursor and the scale rotating with the rotatable element of the mouthpiece, the level of ventilation being indicated by the longitudinal distance between the cursor and a longitudinally aligned point on the scale. |
