Abstract: An article that serves the dual function of a smoking pipe and drinking receptacle, and thereby permits the concurrent smoking of tobacco and consumption of a beverage through use of a single instrument. The article has the general configuration of a mug, comprising an inner shell that forms a reservoir for holding a beverage and a surrounding outer shell having smoke input and output means, a smoke chamber normally containing a smoke filtering agent being provided between the inner and outer shells to accommodate the travel of smoke between said input and output means. The smoke chamber is securely sealed from the reservoir to prevent contamination of the beverage by the smoke or filtering agent, while the inner shell serves to conduct heat between the chamber and reservoir to provide auxiliary cooling of the smoke.
