Pipe

A pipe, in cannabis context, is a handheld combustion device consisting of a bowl, an air chamber or stem, a mouthpiece, and usually a small side hole called a carburetor ("carb"). The archetypal form is the spoon pipe — a rounded bowl at one end transitioning into a straight stem and mouthpiece. Hand pipes are typically palm-sized and made of borosilicate or quartz glass, though metal, wood, ceramic, stone, and silicone are all common. The user packs ground flower into the bowl, covers the carb with a thumb, applies flame while inhaling to build smoke in the chamber, then releases the carb mid-draw to clear the chamber with fresh air. "Cornering" — lighting only one edge of the bowl — preserves unburned flower for subsequent hits. Related hand-pipe variants include the one-hitter or chillum (single-hit cylinder, no carb), the steamroller (larger cylindrical pipe with carb), the Sherlock (curved stem), and the bubbler (hand-sized water pipe). Pipes differ from bongs in that they do not filter smoke through water. → See also: Bowl, Bong. ---
