Abstract

A cigarette filter plug, comprising a wad of cotton wool, has embedded within it one or more small-bored tubes extending longitudinally through the whole or a portion of its length, which thus can be greater than normal. The tubes, preferably made of a plastic material or a plasticized material or a plasticized fabric, are held between two or more slivers of cotton. They may have different lengths.
