Smoking Article

Abstract

A smoking article comprises a distal end which, in use, contains a smoke producing substance. A proximal end has smoke drawn from it during smoking. At least one channel is provided which runs from the proximal end to at least part way towards the distal end. At least one vent hole is arranged such that an airflow path is defined through the vent hole, via the channel and to the proximal end of the smoking article. A smoke supplement composition is housed along the airflow path, such that, when the smoking article is smoked, air is drawn along the airflow path and over the composition so that the composition becomes air born and is delivered to the smoker.
