The porosity of the cigarette paper during smoking of the cigarette will typically be from about 30% to abut 60%. The heat-degradable filler particles are capable of being dissipated at temperatures from about 25° C. to about 350° C. and/or at distances from about 0.1 mm to about 10 mm in advance of a charline formed in the cigarette paper during combustion of the cigarette. Methods of making the cigarette paper, a cigarette using the cigarette paper, and methods for making and smoking such a cigarette are also provided.
