What is Shisha? Separating Fact from Fiction
Shisha is tobacco smoked through a water pipe, and the water does not make it safe. That’s the short version. The longer version involves unpacking years of cultural myth-making that has convinced a lot of people a hookah session is basically harmless fun.
Marcus, 24, thought the same when he started smoking shisha every weekend at a cafe near his university in Leeds. Two years later, he was coughing every morning and craving sessions mid-week. “I genuinely believed it was nothing like cigarettes,” he said. “Then my doctor showed me the numbers.”
Those numbers are not pretty.
What is Shisha and How is it Used?
Shisha tobacco is sweetened, flavored, and heated with charcoal. The smoke travels through a water chamber and up a long hose before you inhale it. The fruity smell and smooth draw are the product’s whole pitch, and they work as effective distractions from what’s actually happening.
The core issue: charcoal combustion, tobacco, and deep inhalation are all present regardless of the flavor. The social setting just means you sit there longer. A typical shisha session runs 45 to 60 minutes, according to the World Health Organization. That is a long time to breathe combustion byproducts.
Myth 1: Shisha is Safer Than Cigarettes
It isn’t. One hour of shisha exposes users to the smoke volume equivalent of 100 or more cigarettes, per WHO estimates. The water cools the smoke so it feels less harsh, which mostly means you inhale deeper and stay at it longer.
Shisha smoke contains carbon monoxide, heavy metals including arsenic and lead, and carcinogens at levels comparable to or exceeding cigarette smoke. The delivery method does not clean the product. It just makes it go down easier.
Myth 2: The Water Filters Out the Toxins
Water does trap some large particles, but nicotine, carbon monoxide, and most toxic compounds pass through with minimal reduction. Studies measuring shisha smoke post-water stage show it retains the large majority of its harmful content.
The cooling effect is real. The filtration effect is mostly folklore. Users interpret the smoothness as purity, and those are not the same thing.
Myth 3: Herbal Shisha is Harmless
Herbal shisha skips the tobacco but keeps the charcoal, and charcoal combustion is a major source of the problem. Burning any plant material with charcoal produces carbon monoxide, polycyclic aromatic hydrocarbons, and tar. Lab tests on herbal shisha products have found toxic metal levels comparable to tobacco-based varieties.
“Tobacco-free” does not mean “smoke-free” or “safe.” The harm in shisha comes from multiple sources, not just the leaf.
Myth 4: Shisha Is Not Addictive
Most shisha tobacco contains nicotine, which creates physical dependence. A single long session can deliver enough nicotine to trigger cravings, particularly because blood nicotine levels have time to climb over a 45-minute sitting.
Beyond the chemistry, the social ritual locks in a behavioral habit that is genuinely hard to separate from the chemical one. Priya, 29, quit cigarettes using nicotine patches but found shisha harder to walk away from. “With cigarettes I was alone. Shisha is always with people. The craving felt social, not just physical.”

Myth 5: Casual Use Carries No Real Risk
Every session carries risk. Carbon monoxide from the charcoal binds to red blood cells and reduces oxygen delivery, even during a single sitting. People with cardiovascular conditions can experience measurable effects from one session.
Long-term intermittent use still accumulates damage. Researchers have not identified a session frequency that eliminates risk, and there is no scientifically established safe dose of shisha smoke. Infrequent use just means slower accumulation.
The Actual Health Effects of Shisha
The research is consistent. Regular shisha use is linked to serious harm across multiple body systems.
| Health Area | Documented Risks |
|---|---|
| Lungs | Chronic bronchitis, emphysema, elevated lung cancer risk |
| Cardiovascular | Heart disease, stroke, elevated resting heart rate and blood pressure |
| Oral Health | Gum disease, oral cancer, tooth decay |
| Infectious Disease | Herpes, hepatitis, and other pathogens spread via shared mouthpieces |
Disposable mouthpieces reduce but do not eliminate transmission risk. Shared hoses remain a clear vector.
Carbon monoxide deserves specific attention. Charcoal-heated shisha produces significantly higher CO levels than cigarettes because you’re burning coal for an extended period in an often enclosed space. A 2017 study in Public Health Reports found CO levels inside hookah lounges exceeded OSHA workplace safety thresholds during busy service periods.
If You’re Thinking About Quitting
Quitting shisha follows the same basic path as quitting cigarettes, but the social element adds friction. Both the physical dependence and the behavioral habit need to be addressed, not just one.
The best quit smoking aids tackle the nicotine side. For the social craving, most people find they need to change the setting first: stop going to the cafe before trying to stop smoking, not the other way around.
