Is smoking a hookah more harmful than smoking a cigarette? That's what one high schooler decided to investigate.  Centennial student Dominique DeVilbiss studied over 400 high school students.  She claims teens mistakenly believe that hookah water filters out chemicals.  She's taking her results to the Young Epidemiology Scholars (YES) Competition in Washington, D.C., this week. She joins us on the phone, and talks about whether hookah smoking is harmless, or turning into a Las Vegas epidemic.
