A smoking product comprising a porous self-supporting central core of carbonized matter circumscribed by tobacco shreds is disclosed. The preferred method for making the core of the smoking product involves the forming of a precursor rod of loosely twisted or substantially non-woven cellulosic material containing additives for ash control, and pyrolyzing said rod by heating in an inert atmosphere to produce a carbonized integral rod consisting of at least about 80 percent carbon. Tobacco shreds and a wrap are applied to the pyrolyzed core to complete the preparation of the smoking product. |
