SAN DIEGO, Aug. 19 (UPI) -- Researchers in California say they've tracked an alarming increase in the use of hookahs -- water pipes used for smoking tobacco -- among young adults.
Researchers at the University of California, San Diego, said hookah use in the state was much higher among young adults aged 18 to 24 -- 24.5 percent among men, 10 percent among women -- than it was among all adults together at 11.2 percent among men and 2.8 percent among women.
