Abstract: A cigarette pipe is disclosed incorporating therewith a replaceable tar cartridge which acts as a liquefier tube. Said tar cartridge is snugly fitted at the downstream portion of the cigarette holder of said pipe. A smoke passage inlet and smoke passage outlets passing to and from said cartridge are tiny orifices of predetermined diameter to produce a low pressure chamber therein. During smoking, a suction pressure is applied at the mouthpiece end and the hot gas molecules of the stream of smoke, through an inlet orifice, flows at high velocity inside the tar cartridge which provides the low pressure chamber and wherein the highly accelerated stream of smoke is expanded, cooled and liquefied. The liquefied tar particles suspended in the stream of smoke sticks and accumulates to the inner walls of the cartridge.
