1. A pipe for use with smoking materials, the pipe comprising:

  • an elongated body having a longitudinal axis and opposite ends, the ends having openings therein, the body having an interior wall defining a passage extending through the body and communicating with the openings at the ends;

    an endpiece removably secured to one of the ends of the body, the endpiece having portions defining a reservoir for smoking materials, the reservoir in communication with the passage in the body when the endpiece is secured to the body;

    the reservoir comprising a base and a side extending from the base and terminating in an edge and having a depth measurable from the edge of the reservoir; and

    means for varying the volume of the reservoir between a maximum volume and a minimum volume by rotating the body relative to the endpiece about the longitudinal axis, whereby the means for varving the volume advances the base toward the edge to decrease the depth of the reservoir when the body is rotated relative to the endpiece in a first direction and retracts the base away from the edge to increase the depth of the reservoir when the body is rotated relative to the endpiece in a second direction.
