Abstract: Cigarette paper containing a filler of gamma alumina, for selectively reducing the organic vapor phase constituents in tobacco smoke. The paper is comprised of cellulosic fibers and a gamma alumina filler with the amount of alumina filler present being at least 50% by weight based on the weight of the paper. Preferably, the amount of gamma alumina filler will range from 50 to 80%. In addition to reducing organic vapor phase constituents, the paper has unique advantages over conventional cigarette paper wrappers in that the visible sidestream smoke eminating from the smoking article is reduced.

Abstract: A paper tobacco substitute which produces a neutral taste when blended with tobacco, comprising cellulose fibers and a filler, said filler comprising at least 55% by weight finely pulverized carbon particles based on the weight of the cellulose. In addition to carbon, the filler may include an alkaline earth metal carbonate or oxide such as calcium carbonate or magnesium oxide to further enhance the properties of the paper as a tobacco substitute. The carbon filled paper may be cut or shredded to simulate natural tobacco and can be used as a blend with tobacco in smoking articles.
