ABSTRACT:
A mouthpiece element for a cigarette comprises a duct which extends from the periphery of the element at a first location, spaced from the mouth end of the element, to the mouth end of the element at a second location, spaced from the periphery of the element. The element is attached to a cigarette rod by tipping which permits the ingress of air to the duct at the first location. Preferably, during smoking the ratio of the velocity of air issuing from the duct at the second location to the velocity of smoke issuing from the mouth end of the element is in excess of at least ten.
