Hookah Smoking and Risks

Hookah is often mistaken as a healthier alternative to cigarette smoking, primarily due to its sweet smell and taste and the fact that people typically smoke hookah only occasionally.

But there's no such thing as a healthy smoking option. Hookah is not healthier than cigarettes, and it carries risks similar to those of cigarette smoking including cancer, heart disease, and lung disease.

What Is Hookah?

A hookah is a water pipe that is used to smoke sweetened and flavored tobacco. Other names people use for hookah are narghile, argileh, shisha, hubble-bubble, and goza. The pipe is usually quite large and consists of a water chamber, a tobacco chamber, and one or more flexible tubes stemming from it that allow multiple people to inhale at the same time.

Hookah tobacco is often sweetened with molasses, fruit pulp, or honey, with additional flavors such as coconut, mint, or coffee. Flavorings sweeten the taste and aroma of tobacco, making it especially appealing to young people.

Aside from tobacco, It's important to note that hookah can be used to smoke herbal shisha, marijuana, and hashish.

Toxins in Hookah

It's a common misconception that hookah smoking removes nicotine and other toxins from tobacco. While water-cooled smoke is less harsh on delicate lung tissue, the toxicity of the smoke is unchanged and the cancer-causing chemicals present in the hookah tobacco are not filtered out by this process. 

Hookah smoke contains many of the same harmful chemicals in traditional cigarette smoke, including:

• Acetaldehyde
• Acrolein
• Arsenic
• Cadmium
• Carbon monoxide
• Chromium
• Cobalt
• Formaldehyde
• Lead
• Nickel
• Polonium 210, a radioactive isotope
• Tar
  

Some hookah tobacco products claim they don't contain tar, but that is misleading. Tobacco doesn't ever contain tar until it is burned, or in the case of hookah tobacco, heated. This difference leads some to believe that the toxicity of hookah tar may be less than that of cigarette tar—but this is not the case.

Additionally, the charcoal that is used to heat the tobacco contains carbon monoxide, metals, and other cancer-causing agents like polyaromatic hydrocarbons, adding another level of danger for those who smoke hookah.

Hookah vs. Cigarettes

The average, manufactured cigarette contains between 7 and 22 milligrams (mg) of nicotine, with about 1mg absorbed by the person who is smoking. An average hookah bowl contains as much nicotine as a pack of 20 cigarettes. Nicotine is an addictive drug, so smoking hookah can be every bit as addictive as smoking cigarettes.

A person smoking hookah inhales about 90,000 milliliters (ml) of smoke in a single 45-minute session; comparatively, someone smoking a single cigarette inhales 500 to 600 ml of smoke.

Those who smoke hookah may take in more of the additional toxins also found in cigarettes—such as tar and heavy metals—because inhalation through the water pipe requires a stronger and longer drag or inhale.

Health Concerns Associated With Hookah

Many health concerns related to hookah smoking are similar to those associated with cigarette smoking, including the risk of cancer, decreased fertility, heart disease, and more.

Addiction

Smoking a water pipe hookah delivers nicotine just as cigarettes and other tobacco products do. Nicotine is highly addictive and can have a variety of health effects. 

Nicotine reaches the brain within seconds, where it acts to trigger the production of adrenaline. Adrenaline is a hormone that plays a role in the body's fight-or-flight response. It causes physiological changes, including increased heart rate, respiration, and blood pressure. 

Cancer

People who smoke hookah are at risk for many different types of cancer, including bladder cancer, esophageal cancer, lung cancer, oral cancer, and stomach cancer.

Damage to Women's Health

One study found that women who smoke hookah are at an increased risk of premature menopause and reduced bone density.

Decreased Fertility

Hookah smoking may lead to decreased fertility among both men and women.

One study found that sperm motility (the ability of sperm to swim in the proper direction) and sperm morphology (the size and shape of sperm) were negatively impacted in men who regularly smoked hookah compared to men who did not smoke hookah.

Heart Disease and Stroke

Hookah smoking raises your blood pressure and your heart rate, which may increase your risk of heart attack and stroke. Hookah smoking can also contribute to clogged arteries and heart disease.

Lung Disease

Even short-term use of hookah is linked with impaired lung function. You might notice you become out of breath more easily when performing physical tasks. Over time, hookah smoking also increases the risk of impaired pulmonary function and lung diseases like chronic obstructive pulmonary disease (COPD).

Pregnancy Risks

Hookah smoking while pregnant is linked with many risks including chromosomal disorders, ectopic pregnancy, infant disease and mortality, intrauterine growth restriction, and low birth weight. Hookah smoking while pregnant also increases the baby's risk for respiratory illnesses.

Secondhand Smoke

Secondhand smoke from hookah is also hazardous. If you're in the room with a lit hookah water pipe, you're breathing in cancer-causing toxins just as you would with secondhand cigarette smoke.

Secondhand smoke can cause heart disease, lung cancer, and stroke in people who are exposed to it, even if they do not smoke themselves.

Spreading Illness

Hookah smoking can also spread illness. Since people are usually in a social setting when they smoke, with several people often sharing the same pipe and sometimes the same mouthpiece. Colds and other infections, including oral herpes, can be easily passed from one person to another.
