Experts say hookah can be just as dangerous as smoking cigarettes

The United States may be winning the war on cigarettes. After decades of public service announcements about the dangers of smoking, fewer teens are lighting up.

But if you ask young Americans about smoking tobacco through a hookah, also called a waterpipe or shisha, there's a good chance you won't find the same level of awareness.

"I've smoked hookah since college, and I can tell you, most of my friends think it's safer than cigarettes," said Bruce Kafil, an avid hookah smoker and the owner of Lotus hookah lounge in Los Angeles.

A new study published Monday in the journal Pediatrics finds about 18% of high school seniors have tried hookah.

Researchers used survey data taken between 2010 and 2012 from 5,540 high school seniors around the country. They found that teens of higher socioeconomic status -- those who had a weekly income or whose parents were well-educated -- were more likely to be hookah smokers.

Hookah originated in the Persian Empire in the 16th century. Waterpipes burn charcoal, which then heats up tobacco and produces smoke. The fumes are cooled by bubbling through a water-filled chamber before being inhaled.

Hookah smokers traditionally use tobacco without added flavoring. But mixing tobacco with flavors like green apple, coconut and even bubble gum is now all the rage. Appealing flavors mask the harsh nature of hookah tobacco and attract younger smokers, says Dr. Vinayak Prasad, senior adviser for the World Health Organization's Tobacco-Free Initiative.

Kafil says there's a "cool" factor to hookah, and the fruit-scented smoke makes it hard to fathom dangerous consequences.

"I don't smoke cigarettes because I can't handle the terrible smell," Kafil said. "Hookah smoke is pleasant. Even the parents of college students who smoke (at the Lotus hookah lounge) are surprised at how nice it smells."

The CDC says the drop in cigarette use is being offset by other forms of tobacco, including hookah, e-cigarettes and smokeless tobacco products.

Between 2011 and 2012, hookah use rose from 4.1% to 5.4% among high school students, according to the CDC. Even middle school students are joining in; a 2013 CDC report says 1.3% of middle schoolers reported recent hookah use. And studies show around 40% of American college students have tried hookah.

Hookah is a great way to socialize because several friends can share one pipe for hours, says Kafil.

"When I was in college, smoking at hookah lounges was a great option since none of my friends or I could drink at bars," he said.

But experts say hookah can be just as dangerous as smoking cigarettes. Burning charcoal and tobacco means the smoke contains high levels of metals, carbon monoxide and cancer-causing chemicals, says Dr. Norman Edelman, senior medical adviser for the American Lung Association.

Hookah users may be exposed to even higher concentrations of toxins than cigarette users -- because they inhale more deeply, puff more often, and tend to smoke for longer periods of time, according to the CDC. A typical hookah session lasts an hour and involves 200 puffs, while an average cigarette is only 20 puffs.
