Claim:
1. A smoking article comprising: a first segment; a second segment; and an aerosol generating substrate coupled to the first and second segments; wherein at least one of the first and second segments comprises a vapour release portion; wherein the first and second segments are movable relative to each other from a first configuration to a second configuration such that the smoking article is provided with a changeable length; wherein in the first configuration the first segment and the second segment interact to form an airflow pathway that does not incorporate the vapour release portion, the vapour release portion being thus substantially isolated from the airflow pathway, wherein in the second configuration the vapour release portion is exposed to the airflow pathway, wherein the first segment comprises the vapour release portion and the second segment defines a cavity that is adapted to receive at least a section of the vapour release portion, wherein in the second configuration a section of said vapour release portion remains partially within the cavity, and wherein said vapour release portion has substantially impermeable end surfaces and a permeable side surface, and said cavity has a substantially impermeable inner surface such that in the first configuration the impermeable surfaces form a vapour container to isolate the vapour release portion from the airflow pathway.
