A water pipe or bong (not to be confused with bhang, an Indian term for a mixture of milk and hashish) is an object most often used for smoking cannabis. It is also used to smoke other substances such as tobacco. Smoking with a water pipe would be appreciated for the very different experience than smoking a pipe or a joint. Water pipes are used for the purpose of generating and cooling a large amount of smoke, which the user will usually inhale in one puff. The word bong is a word derived from the Thai word bΔung which refers to a cut piece of bamboo.
