Abstract
A self-extinguishing pipe is described for use with tobacco or other smoking material. The pipe is made in two parts, a body and an endpiece, and holds a filter internally. The endpiece includes a reservoir for the tobacco or other smoking material at one end which has an adjustable base for changing the depth of the reservoir. The two-part construction and adjustable base facilitate cleaning of the pipe, replacement of the filter, and removal of ash without needing additional tools. The depth of the reservoir is adjusted by rotating an inner component of the endpiece in relation to a surrounding cowl. Various bores through the body of the pipe and the components of the endpiece communicate with each other so as to form an air passage from the smoking material to the mouth end of the pipe, thereby allowing smoke to be drawn into the user's mouth.
