Abstract

A filter cigarette with variable ventilation includes a rod of smokable material, a mouthpiece including an element rotatable relative to the rest of filter cigarette about the longitudinal axis thereof to vary the ventilation of the filter cigarette, and a ventilation indicator including a scale extending circumferentially about the periphery of the filter cigarette and a cursor. The scale is symmetric about the longitudinal axis of the filter cigarette and the cursor and the scale are rotatable relative to one another about the longitudinal axis of the filter cigarette. One of the cursor and the scale rotate 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.
