Abstract
This invention provides a smoking article (1) having reduced sidestream smoke in the inter-puff period. A smoking article (1) according to the invention may comprise segments of a high level of tobacco-containing material (5) interconnected by segments of low level of tobacco-containing material (6) which are capable of maintaining smoulder in the inter-puff period and re-igniting the segments of a high level of tobacco-containing material (5) in the puff period. Alternatively, a smoking article according to another aspect of the invention may comprise a lengthwise, axially extending, tobacco-containing fuse portion (46) which sustains smoulder in the inter-puff period when surrounding tobacco material (45) is substantially extinguished and which re-ignites the extinguished material on puffing of the smoking article (1).
