Abstract

A tobacco product comprising nanocrystalline particles and methods of reducing the levels of undesirable compounds in tobacco smoke are provided. The nanocrystalline particles are effective sorbents of numerous toxic compounds released by burning tobacco and may be incorporated into the tobacco itself, incorporated into a filter element, or incorporated into the fibers of a wrapping paper.
