Abstract

A tobacco smoking device comprises a porous mass of active particles adapted to enhance a tobacco smoke flowing over said active particles and binder particles. The active particles comprises about 1-99% weight of the porous mass, and the binder particles comprises about 1-99% weight of said porous mass. The active particles and said binder particles are bound together at randomly distributed points throughout the porous mass. The active particles have a greater particle size than the binder particles.
