A bong, also commonly known as a water pipe, is a smoking device, generally used to smoke cannabis, tobacco, or other substances.^[1][2] The construction of a bong and its principle of action is similar to that of the hookah, which is also called "water pipe." A bong may be constructed from any air- and water-tight vessel by adding a bowl and stem apparatus (a slide)^[3]. The word bong is an adaptation of the Thai word baung (Thai: บ้อง /bɔːŋ/),^[4] 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 the West is the McFarland Thai-English Dictionary, published in 1944, which describes one of the meanings of bong in the Thai language as, "a bamboo waterpipe for smoking kancha, tree, hashish, or the hemp-plant." A January 1971 issue of the Marijuana Review also used the term.^[5]

Comparison with other smoking methods

The physics of a bong are similar to those of a laboratory gas washing bottle. The gas (smoke) is passed through the water to remove solids and particulate from the gas (smoke).

The rationale behind the use of a bong is the claim that the cooling effect of the water helps to reduce the chance of burning the mouth, airways, and lungs, thus many claim that using a bong to smoke is safer. The water can trap some heavier particles and water-soluble molecules, preventing them from entering the smoker's airways.^[6] Thus the mechanics of a bong function similarly to those of a laboratory gas washing bottle. This "filtration" can lead to the belief that bongs are less damaging than other smoking methods.

A variety of pipes and bongs for sale. In countries where marijuana is illegal, retailers often specify their use for tobacco in an attempt to circumvent laws against selling drug paraphernalia.

However, 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".^[7] 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^[8] 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."^[9] This study suggests that a bong's smoke is less harmful than unfiltered smoke.

Legality

Bongs are often sold in head shops and on the Internet. In the United States, under the Federal Drug Paraphernalia Statute, which is part of the Controlled Substances Act, it is illegal to sell, transport through the mail, transport across state lines, import, or export drug paraphernalia. Nonetheless, the sale of bongs is tolerated as are other general purpose smoking tools, including rolling papers, crack pipes, etc.^{[citation needed]}

In countries where marijuana and hashish is illegal, some retailers specify that bongs are intended for use with tobacco in an attempt to circumvent laws against selling drug paraphernalia. While technically 'bong' does not mean a device used for smoking marijuana, drug-related connotations have been formed with the word itself. Due to these connotations, some head shops will not serve customers who use the word "bong".^[10]
