Abstract
A cigarette-type smoking article has a short tobacco-containing fuel element, a passageway for mainstream tobacco smoke flow, a flavor source which provides enhanced flavor to the tobacco smoke which passes therethrough, and a mouthend piece. The article is highly air diluted and the air dilution is provided through the periphery of the article as perforations in a region immediately behind the fuel element. Such an article delivers highly flavored mainstream tobacco smoke and relatively low levels of pyrolysis and/or combustion derived wet total particulate matter.
