Abstract

See full text

A smoking article such as a filter cigarette can have an adjustable delivery air dilution while exhibiting a reduced pressure drop decrease during air dilution thereof. The pressure drop decrease is controlled during various stages of air dilution by positioning the structure for greatest air dilution on the cigarette a greater distance from the extreme mouthend of the cigarette relative to the structure for least air dilution. Filter cigarettes of this invention are capable of exhibiting a somewhat constant smoking character at various air dilution levels.
