A bong, also commonly known as a water pipe, is a smoking device, generally used to smoke cannabis, tobacco, or 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.

Etymology

The word bong is an adaptation of the Thai word baung (Template:Lang-th /bɔːŋ/), a cylindrical wooden tube, pipe, or container cut from bamboo, and which also refers to the bong used for smoking. Bongs have been in use, primarily by the Hmong, in Laos and Thailand, for centuries. One of the earliest recorded uses of the word in Western literature dates to a piece in the January 1971 issue of the Marijuana Review. An even earlier reference, the McFarland Thai-English Dictionary, published in 1944 describes one of the meanings of bong in the Thai language as, "a bamboo waterpipe for smoking kancha, tree, hashish, or the hemp-plant."

Operation

To use a bong, the base of the bong pipe is filled with water or other liquids. While alcoholic beverages or oils can be used in a bong, both of these substances filter out some of the THC when the bong is used for smoking marijuana, because THC is fat-soluble and, to a lesser extent, alcohol-soluble. THC is only very slightly water-soluble, which makes water a good choice of fluid for filling a bong. The substance to be smoked is packed into the cone piece and ignited.

Comparison with other smoking methods

Bong advocates claim that the cooling effect of the water helps to reduce the chance of burning the mouth, airways, and lungs. The water can trap some heavier particles and water-soluble molecules, preventing them from entering the smoker's airways. While smokers tend to believe that bongs are less damaging than other smoking methods, a 2000 NORML-MAPS study found that "water pipes filter out more psychoactive THC than they do other tars, thereby requiring users to smoke more to reach their desired effect". In the study, smoke from cannabis supplied by the NIDA was drawn through a number of smoking devices and analyzed. An inhalation machine, adjusted to mimic the puff length of cannabis smokers, drew smoke through a standard bong, a small portable bong with a folding stem, a bong with a motorized paddle that thoroughly mixes the smoke with the water, and two different types of vaporizers. Comparisons to traditional non-filtered smoking methods were not included in these experiment.

MAPS also reviewed a study that examined the effects and composition of water-filtered and non-filtered cannabis and tobacco smoke. It found that when alveolar macrophages were exposed to unfiltered smoke, their ability to fight bacteria was reduced, unlike exposure to water-filtered smoke. It also found substantial epidemiological evidence of a lower incidence of carcinoma among tobacco smokers who used water-pipes, as opposed to cigarettes, cigars, and regular pipes. "It appears that water filtration can be effective in removing components from cannabis smoke that are known toxicants... The effectiveness of toxicant removal is related to the smoke's water contact area. Specially designed water pipes, incorporating particulate filters and gas-dispersion frits, would likely be most effective in this regard; the gas-dispersion frit serves to break up the smoke into very fine bubbles, thereby increasing its water-contact area." This study suggests that a bong's smoke is less harmful than unfiltered smoke.
