A bong is a water pipe that filters smoke from cannabis before you inhale it. It’s vertical, consisting of a base (where the water goes) and a chamber where you draw in smoke. Like a pipe, a bong has a bowl for cannabis; smoke then travels through the downstem and into water, and then into the main chamber to be inhaled. Bongs are typically less harsh than pipes because the smoke is filtered through water.
“My friend brought over his six-foot bong and we got absolutely ripped.”
“I’m going to change out the water in this bong so we can get some clean hits.”
