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.
