Abstract
A tobacco smoke filter is made of the stem of a tobacco plant, free of leaf, from which the greater part of the nicotine and of the tarry content has been removed. The stem may comprise the veins of tobacco leaves, free of leaf, and may be formed into fibres. The fibres may be subsequently bleached or coloured as desired and may be impregnated with absorption capacity accelerators and aromaticizing substances.
