 a second wrapping paper around the filter portion. 
   
     
     
         5 . The smoking article of  claim 4 , wherein the second wrapping paper at least partially defines the interface. 
     
     
         6 . The smoking article of  claim 4 , further comprising:
 a third wrapping paper around the filter portion, the third wrapping paper positioned between the second wrapping paper and the filter portion.   
     
     
         7 . The smoking article of  claim 6 , wherein the third wrapping paper at least partially defines the interface. 
     
     
         8 . The smoking article of  claim 6 , wherein the third wrapping paper includes an inner adhesive line for adhering the third wrapping paper to the filter portion. 
     
     
         9 . The smoking article of  claim 1 , wherein the interface is completely defined by the inner surface of the wrapping paper, the mouth end of the tobacco filler material, and a cap or plug on a mouth end of the tobacco filler material. 
     
     
         10 . The smoking article of  claim 1 , wherein the interface is empty.
