- Essential for bong operation, a downstem is a small, removable piece of glass that houses ground cannabis. Once lit, the user inhales from the mouthpiece, filling the chamber with smoke. Removing the downstem at this point then allows the user to inhale the produced smoke inside the chamber. They also tend to be the most delicate part of the bong, but thankfully, many head shops and dispensaries sell spares.
