ABSTRACT:
A ventilated smoking pipe comprises a bowl having a cavity and an integral stem portion with a short passageway adjacent a bottom portion of the bowl opening into the bowl cavity at one end and into the stem at the remote end. A longitudinal ventilation chamber is formed in the stem communicating with the passageway in the bowl having a substantially uniform cross-section larger than that of the passageway and extending from adjacent the bowl on one end along substantially the entire length of the stem. An air hole is formed in the stem communicating with the ventilation chamber intermediate the end thereof for introducing fresh outside air into the chamber reducing the moisture content and cooling the smoke as it passes through the stem.
