Abstract
Abstract A smoking article containing an ignition suppression disk is disclosed. The smoking article comprises a tubular smoking wrapper having tobacco therein extending from about one-half to about two-thirds of the length of the wrapper and terminating at a face against which a disk is placed that suppresses ignition. The disk prevents the smoking article from being consumed beyond one-half to about two-thirds the length thereof. A short fill of tobacco in between the disk and the mouthpiece of the smoking article prevents the consumption of the short fill which generally contains the most harmful smoking by-products in highest concentration since the short fill acts as a filter. A non-tobacco filter may be employed on the mouthpiece end of the smoking article.
