Cut filler compositions, cigarettes, methods for making cigarettes and
methods for smoking cigarettes are provided, which involve the use of an
oxyhydroxide compound that is capable of decomposing to form at least one
product capable of acting as an oxidant for the conversion of carbon
monoxide to carbon dioxide and/or as a catalyst for the conversion of
carbon monoxide to carbon dioxide. The oxyhydroxide compound and/or the
product formed from the decomposition of the oxyhydroxide can be in the
form of nanoparticles. Cut filler compositions are described which
comprise tobacco and at least one such oxyhydroxide compound. Cigarettes
are provided, which comprise a tobacco rod, containing a cut filler
having at least one such oxyhydroxide compound. Methods for making a
cigarette are provided, which involve (i) adding at least one such
oxyhydroxide compound to a cut filler; (ii) providing the cut filler
comprising the oxyhydroxide compound to a cigarette making machine to
form a tobacco rod; and (iii) placing a paper wrapper around the tobacco
rod to form the cigarette. Methods of smoking the cigarette, as described
above, are also provided, which involve lighting the cigarette to form
smoke and inhaling the smoke, wherein during the smoking of the
cigarette, the oxyhydroxide compound decomposes during smoking to form a
compound that acts as an oxidant for the conversion of carbon monoxide to
carbon dioxide and/or as a catalyst for the conversion of carbon monoxide
to carbon dioxide.
