An improved cigarette is prepared through use of modified cigarette paper as a wrapper. The wrapper is treated in preselected areas with a burn control additive comprising a mixture of potassium chlorate and sodium chlorate in a molar ratio of from 2.6:1 to 1.0:1. When the burning coal reaches the area of treatment, the treated area is burned away, allowing for the passage of air through the opening created during smoking of the cigarette. The mixture of potassium chlorate and sodium chlorate provides for a more stable treatment, particularly when the cigarettes having the thus treated wrapper are stored under conditions of high humidity.read more
