A water bong, also known as a bong or waterpipe, is a filtration device used to smoke cannabis or other herbal substances. It consists of a bowl, a stem, a chamber, and a mouthpiece. The smoke from the bowl is drawn through the stem and into the chamber, where it is cooled and filtered by the water. The filtered smoke is then inhaled through the mouthpiece.
Water bongs have been used for centuries by various cultures around the world. They are popular because they provide a smoother and less harsh smoking experience than other methods, such as joints or pipes. Water bongs also filter out some of the harmful toxins and carcinogens that are present in smoke.
