摘要： A smoking device includes a pipe made of an elongated glass tube having an open first end and an open second end. An internal surface of the elongated glass tube includes a narrowed portion defining a narrowed diameter opening. The narrowed portion separates chambers within the elongated glass tube. The chambers include a material chamber from the second open end to the narrowed portion, and a smoke chamber defined from the narrowed portion to the first open end. A cap includes an open end and output openings. The cap is placed over the open first end or the open second end. The pipe further includes a polymer coating sealed to an outer surface of the elongated glass tube.
