Patent

CA 2553414

A smoking article (10) having reduced ignition propensity is disclosed. The smoking article includes a tobacco column (12), a wrapper (14) surrounding the tobacco column (12), and a filter element (16). The wrapper (14) has a base permeability, and untreated area (20) and at least one discrete area (22) treated with a composition to reduce the base permeability. The discrete treated area (22) interacts with a coal of a burning tobacco firecone as it advances to self-extinguish the smoking article (10). The composition of the treated area (22) includes a permeability reducing substance, a bum rate retarding substance and a burn rate accelerating substance. Either the burn rate retarding substance or the burn rate accelerating substance acts as an organoleptic enchancing substance. In this way, a smoker's experience when smoking either the at least one treated area (22) or the untreated area (20) is substantially the same.
