Hookahs are smoking devices featuring long flexible tubes. Smoke is pulled through water, and thus cooled, before traveling through a tube and inhaled. Hookahs can have several pipes emanating from the central column, allowing multiple users to smoke from the same device without passing it around. Hookahs range in price from around $20 to as much as $600 for specialty models.
However, hookahs are more popular around the world for smoking various types of flavored tobacco, instead of only marijuana. In addition, marijuana smoked in a hookah is said to taint the flavor of tobacco in the device for future use.
