- 25. A smoking article having a low carbon monoxide delivery comprising:
a column of a smokable filler; and a wrapping paper surrounding said column of said smokable filler, said wrapping paper comprising a paper substrate containing a filler, said wrapping paper having a basis weight of up to about 30 gsm and a fiber basis weight of less than about 18 gsm; and wherein when said smoking article is smoked, said smoking article produces a carbon monoxide delivery of less than about 18 mg.
- 26. A smoking article as defined in claim 25, wherein said smoking article has a carbon monoxide delivery of less than about 17 mg per cigarette.
- 27. A smoking article as defined in claim 25, wherein said smoking article has a carbon monoxide delivery of less than about 15 mg per cigarette.
- 28. A smoking article as defined in claim 25, wherein said wrapping paper has a fiber basis weight of less than about 15 gsm.
- 29. A smoking article as defined in claim 25, wherein said wrapping paper has a permeability of from about 15 Coresta units to about 55 Coresta units and a basis weight of less than about 22 gsm, said filler comprising a white pigment having a median particle size of from about 0.2 microns to about 0.4 microns, said wrapping paper having a total filler content of from about 15% to about 35% by weight.
