ABSTRACT:
A smoking aid for reducing concentrations of poisonous substances contained in tobacco smoke including a pipe bowl having a smoke retaining cavity, a stem coupled with the pipe bowl and a mouthpiece connected to the stem. A cap-like member is movably secured to a top portion of the pipe bowl such that a space formed between the pipe bowl and cap-like member can be adjusted. A hole is formed in a top wall of the cap-like member, through said hole a root portion of a cigarette may be protruded into the smoke retaining cavity. By moving the cap-like member relative to the pipe bowl to adjust a dimension of the space, it is possible to adjust an amount of clean air introduced into the smoke retaining cavity to control a dilution of tobacco smoke.
