A hookah, or water pipe, is typically made of glass. Water is used to cool tobacco smoke before inhalation. The hookah originated in India and Iran in the sixteenth century, where it was seen as a good way to purify the smoke before it entered a person's body. The hookah soon spread into Pakistan and the Middle East. It has since become popular in other parts of the world and hookahs can be found in North and South America, Europe, Australia and parts of Africa.
