This article provides a review of tobacco smoking using a hookah, an emerging threat to public health, especially among young adults. Knowledge deficits persist in regards to this form of smoking, because many perceive it as less harmful than cigarette smoking and little research is available. Knowledge about hookah smoking can be instrumental in guiding health professionals to address this practice with their clients and in their communities. A failure to address all tobacco products as unique, individual entities undermines any success in public policy efforts to control tobacco use.
