Abstract
In one aspect, the invention provides a simple, readily manufacturable, low tar cigarette with individual puff deliveries similar to those obtained from conventional cigarettes which have a higher total smoke delivery such as a full flavor cigarette. The low tar cigarette includes a tobacco rod segment having a length of 53 mm. or less abutting a filter segment having an overall length of at least 31 mm. wherein the filter segment includes a synthetic fiber filter plug and provides a smoke delivery reduction of at least 55% and wherein the cigarette has an average puff count of 6.5 or less. In another aspect, the invention provides nonconventional smoking articles which have an elongated nonsmokable mouthend portion, i.e., greater than 3/8 of the length of the smoking article, yet have the appearance of conventional filtered or non-filtered cigarette wherein the elongated nonsmokable mouthend portion is wrapped with a tipping paper which bears on at least a portion of its surface adjacent its edge nearest the lighting end of the cigarette, a verge pattern visually similar to the verge pattern on a conventional cigarette paper.
