ABSTRACT OF THE DISCLOSURE This invention relates to smoking articles having reduced free burn time, including cigarettes, cigars and little cigars. The smoking article comprises tobacco wrapped in a paper having at least one circumferential band printed between the ends of the smoking article; preferably at about the center of the smoking article. The band contains a substance which will cause the smoking article to extinguish in about 2-5 minutes under free burn conditions after the cone reaches the banded area if it is not puffed. The band is typically about 2-10 mm wide containing a substance which is a liquid in the temperature range of about 100°C to 200°C and which as the burning cone comes in contact with it pro- vides a fluid film on the paper, without substantially pene- trating through the surface of the paper, which film is sub- stantially impervious to air and decomposes and/or distills endothermically from about 140°C to 300°C to yield gaseous decomposition products normally present in the smoke of smoking articles without the band. The amount of the substance used in the band should be sufficient to extin- guish the smoking articles under free burn conditions within 2-5 minutes. -24-
