Futurity -- U. FLORIDA (US) — Patrons who frequent hookah cafés have carbon monoxide levels more than three times higher than those who visit traditional bars. The social nature of hookah smoking, which is often shared in groups, makes it appealing to young people, says Tracey Barnett, assistant professor of social and behavioral sciences at the University of Florida. “There is also a common misperception that hookah smoking is a harmless alternative to cigarette smoking.”
