ABSTRACT:
Cigarettes which yield low levels of visible sidestream smoke upon use employ an outer paper wrapping material including magnesium hydroxide, calcium carbonate and flax fibers. The outer wrapping material has an inherent permeability of about 10 CORESTA units. The wrapping material contains an amount of water soluble alkali metal salt sufficient to provide at least about 30 mg water soluble alkali metal ions per gram of dry base web. The alkali metal salt normally is such that the wrapping material includes a significantly greater level of potassium ions than sodium ions. The cigarettes also employ an inner paper wrapping material including carbonaceous material and/or tobacco.
