Hookahs

Overview

• Hookahs—sometimes called water pipes—are used to smoke specially made tobacco that is available in a variety of flavors (e.g., apple, mint, cherry, chocolate, coconut, licorice, cappuccino, and watermelon).^1,2

• Hookah is known by a number of different names, including narghile, argileh, shisha, hubble-bubble, and goza.^1,2
• Hookahs vary in size, shape, and composition.²
• A typical modern hookah comprises a head (with holes in the bottom), a metal body, a water bowl, and a flexible hose with a mouthpiece.⁴

Compared with Cigarettes

While many hookah smokers may consider this practice less harmful than smoking cigarettes, hookah smoking carries many of the same health risks as cigarettes.^1,2

• Water pipe smoking delivers the addictive drug nicotine and is at least as toxic as cigarette smoke.²
• Due to the mode of smoking—including frequency of puffing, depth of inhalation, and length of the smoking session—hookah smokers may absorb higher concentrations of the toxins found in cigarette smoke.^1,2
• A typical 1-hour-long hookah smoking session involves inhaling 100–200 times the volume of smoke inhaled from a single cigarette.⁴
• Hookah smokers are at risk for the same kinds of diseases as are caused by cigarette smoking, including oral cancer, lung cancer, stomach cancer, cancer of the esophagus, reduced lung function, and decreased fertility.⁵

Health Effects

Hookah Smoke and Cancer

• The charcoal used to heat tobacco in the hookah increases the health risks by producing high levels of carbon monoxide, metals, and cancer-causing chemicals.^1,4
• Even after it has passed through water, the smoke produced by a hookah contains high levels of toxic compounds, including carbon monoxide, heavy metals, and cancer-causing chemicals.⁴
• Hookah tobacco and smoke contain numerous toxic substances known to cause lung, bladder, and oral cancers.^1,4
• Irritation from exposure to tobacco juices increases the risk of developing oral cancers. The irritation by tobacco juice products is likely to be greater among hookah smokers than among pipe or cigar smokers because hookah smoking is typically practiced (with or without inhalation) more often and for longer periods of time.⁶

Other Health Effects of Hookah Smoke

• Hookah tobacco and smoke contain numerous toxic substances known to cause clogged arteries and heart disease.^1,4
• Infectious diseases may be transmitted by sharing a hookah.²
• Babies born to women who smoked one or more water pipes a day during pregnancy have lower birth weights (were at least 3½ ounces less) than babies born to nonsmokers and are at an increased risk for respiratory diseases.⁵

Hookahs and Secondhand Smoke

• Secondhand smoke from hookahs poses a serious risk for nonsmokers, particularly because it contains smoke not only from the tobacco but also from the heat source (e.g., charcoal) used in the hookah.^1,4
