Hookah is often smoked in group settings and at commercial establishments such as hookah bars and is available in a variety of fruit and candy flavors. Young adults are misinformed about the risks: 24.5 percent of young adults 18 to 34 years old say hookah is less risky than cigarettes. But a typical 1-hour long hookah smoking session can result in the inhalation of the amount of smoke produced by 100 or more cigarettes.
