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.
