Abstract
There is provided a smoking article (100) incorporating an additive delivery system. The additive delivery system comprises a frangible capsule (110) comprising a breakable shell containing a liquid core. The shell can be broken by means of a pressure to release a single burst of the liquid core. Further, the additive delivery system comprises a sustained-release liquid delivery material (111) comprising a liquid composition. The liquid composition is releasable in discrete amounts from the liquid delivery material upon compression of the liquid delivery material so as to selectively combine the first and second additive. The frangible capsule and the sustained-release liquid delivery material are spaced apart, such that a consumer can separately and selectively activate the release of additive from either component of the delivery system.
