MEMPHIS , Oct. 17 (UPI) -- University of Memphis researchers say the use of water pipes, also known as hookahs, hubble-bubbles, narghiles, shishas, gozas or narkeelas, is increasing.

Dr. Wasim Maziak of the University of Memphis and colleagues searched for published and unpublished water pipe cessation trials in any language -- especially in areas of the world where water pipe use is widespread, but could find none.

"As water pipe use is increasing throughout Europe and North America it is very important that we initiate comprehensive research efforts to combat this looming epidemic," Maziak said in a statement.

Maziak said many believe that because the tobacco smoke is drawn through water, it is less harmful, but the evidence accumulated so far does not support that assumption.

It also appears that using a water pipe is as addictive as other forms of tobacco smoking, Maziak added.

The findings are published in the Cochrane Library.
