Abstract:
The present invention relates to a smoking article (9) comprising a mouthpiece (1), a color change segment and a rupturable, fluid-containing capsule (5). The color change segment is adapted to interact with the fluid from the rupturable fluid-containing capsule such that, upon interaction, the color change segment shows a color change when the capsule is ruptured. The smoking article comprises a permeable outer wrapper which is in a first region covered with an impermeable coating such that the first region is impermeable, wherein a second region, which is not covered by the impermeable coating, is permeable.
