Smoking articles having reduced ignition proclivity characteristics are disclosed. The smoking articles include a wrapper comprising cellulosic fibers and a filler. In accordance with the present disclosure, the filler has a particle size of at least about 3.2 microns and is present in the wrapper in an amount less than about 20% by weight. Further, the wrapper may have a basis weight of less than about 23 gsm and a permeability of from about 15 Coresta to about 110 Coresta. It has been discovered that such wrappers are capable of reducing the ignition proclivity characteristics of a smoking article. If desired, the particular wrapper as described above can also contain discrete areas treated with an ignition reducing composition which further serves to reduce the ignition proclivity characteristics of the article.

Wrappers for smoking articles having reduced diffusion leading to reduced ignition proclivity characteristics

The present invention is directed to smoking articles having reduced carbon monoxide delivery are described. A carbon monoxide reducing agent is incorporated into the smoking article in order to reduce carbon monoxide levels in mainstream smoke. The carbon monoxide reducing agent may be, for instance, in metal oxide or in metal carbonate. The carbon monoxide reducing agent may be incorporated into a wrapper and/or into a column of smokable filler that are used to construct the smoking article.
