Cigarettes which yield low levels of visible sidestream smoke upon use employ a paper wrapping material having about 25 weight percent magnesium hydroxide, about 15 weight percent calcium carbonate and about 60 weight percent flax. The wrapping material has an inherent permeability of about 20 CORESTA units. The wrapping material contains an amount of water soluble alkali metal salt sufficient to provide at least about 35 mg water soluble alkali metal ions per gram of dry base web. The alkali metal salt is such that the wrapping material includes a significantly greater level of potassium ions than sodium ions. The wrapping material includes at least one organic acid. The cigarette includes a filter element which has an organic acid incorporated therein. The cigarettes, when employed, provide cohesive ash which is not highly flakey.
