A hookah is basically a water pipe intended for the smoking of tobacco. It is often made of glass with two or more flexible stems drawing the water cooled smoke from the Smoking Pipe. It originated in India many centuries ago, and moved from there into the Middle East. Although tobacco was the original substance burned in the hookah, others are also used. Some of these others have been illegal substances such as Cannabis or Opium, and this has tended to give hookahs a bad name in Western Culture. In recent years, the hookah has been making some headway in dispelling this bad reputation. One of the attractions of hookah smoking in the East was the manner in which the activity induced relaxation, and stimulated conversation.
