A smoking article is provided comprising a rod of aerosol generating material (3) and a filter element (5) attached to an end of the rod of aerosol generating material (3) by means of a tipping paper (7) such that the rod and filter element extend along a longitudinal axis. The filter element comprises a cavity (9) containing an additive (11) and is at least partially surrounded by substantially transparent or semi-transparent wrapper (13) such that the additive in the cavity is visible through the wrapper (13). The tipping paper (7) comprises at least two cut-out windows (15) arranged to allow light to enter the cavity (9) in the filter element from at least two different directions perpendicular to the longitudinal axis. The additive (11) fills between about 10 to about 60% of the cavity. |
