A bong, also commonly known as a water pipe, is a smoking device, generally used to smoke marijuana and tobacco, but also other substances. The construction of a bong and its principle of action is similar to that of the hookah, which is also called "water pipe". Smoking a bong contrasts with smoking a pipe or cigarette in two major ways: bongs cool the smoke before it enters the user’s lungs (making it easier to smoke), and a large amount of smoke is inhaled quickly as opposed to the smaller, more frequent, inhalations of pipe and cigarette smoking
