Hookah is just one name for a type of tobacco smoking called waterpipe smoking. Other common names include Shisha and Narjila. All types of waterpipes have their roots in India, Africa, and the Middle East. Hookah smoke use an indirect heat source (such as lit charcoal) to slowly burn tobacco leaves while users draw smoke through a water chamber and into their mouth using hoses. The introduction of ma’assel, a molasses-soaked smoking tobacco, in the early 1990s has led to growth of hookah smoking across the Middle East and other regions.
