Abstract
The invention relates to low delivery cigarettes, usually having a mainstream particulate matter delivery of about 9 mg or less. An embodiment has a rod of tobacco material and a filter element. The filter element is an alkali filter material section having a loading level of less than 12% by weight of the section. The characteristics of the cigarettes are arranged so that, when smoked, the alkaline filter material is exposed to an amount of smoke acceptable to achieve an increased perception of smoke impact.
