A smoking article, such as a cigarette, includes an air impermeable generally cylindrically shaped plug located in coaxial abutment to one end of the tobacco column of the cigarette and a generally cylindrically shaped filter rod located in coaxial abutment with the plug. The plug is formed with a plurality of grooves in its peripheral surface extending generally longitudinally of the plug from one end to the other end thereof. Air permeable tipping material circumferentially surrounds the impermeable plug and the filter rod, and overlaps a portion of the tobacco column adjacent to plug to fasten the plug and filter rod to the tobacco column. |
