Burning charcoal on a shisha bowl

Charcoal, Carbon Monoxide and Shisha

July 21, 2026Anders Signell

When discussing the health risks of shisha, most attention is placed on tobacco and nicotine. However, public health authorities identify another major danger: burning charcoal.

Charcoal is a key source of toxic exposure during shisha smoking and significantly increases health risks.


Why Charcoal Is Central to Shisha Smoking

Unlike cigarettes, shisha relies on burning charcoal to heat the tobacco or herbal mixture.

This combustion process produces smoke and toxic gases that are inhaled alongside shisha smoke.


Carbon Monoxide Exposure From Shisha

According to the World Health Organization (WHO) , charcoal used in waterpipe smoking is a major source of carbon monoxide (CO).

Carbon monoxide is a poisonous gas that:

  • Reduces oxygen delivery in the blood
  • Increases strain on the heart
  • Can cause dizziness, headaches, and nausea

Water does not filter carbon monoxide from shisha smoke.


CDC Findings on Charcoal and Shisha

The CDC reports that shisha smokers can be exposed to higher levels of carbon monoxide than cigarette smokers, largely due to charcoal combustion.

This risk is especially high during long sessions and in poorly ventilated spaces.


“Natural” or Coconut Charcoal Is Not Safe

Some shisha users believe that natural or coconut-based charcoal is safer.

Public health authorities emphasize that all charcoal produces carbon monoxide when burned, regardless of its source.

Switching charcoal types does not eliminate the core health risk.


Why Charcoal Makes Shisha Particularly Dangerous

Charcoal increases shisha-related harm by:

  • Adding carbon monoxide exposure
  • Extending session duration
  • Encouraging deeper inhalation of smoke

This combination makes shisha uniquely harmful compared to many other tobacco products.


How Smoke-Free Alternatives Compare

Smoke-free nicotine products such as nicotine pouches and vaping products do not require charcoal and do not produce carbon monoxide from combustion.

According to the Royal College of Physicians , eliminating combustion significantly reduces exposure to the most harmful substances associated with smoking.


Frequently Asked Questions

Does charcoal make shisha more dangerous?

Yes. Charcoal produces carbon monoxide and toxic gases that increase health risks.

Is coconut charcoal safer?

No. All charcoal produces carbon monoxide when burned.

Do nicotine pouches involve carbon monoxide?

No. Nicotine pouches do not involve combustion or smoke.


Conclusion

Charcoal is one of the most overlooked but dangerous aspects of shisha smoking. Public health authorities identify charcoal-related carbon monoxide exposure as a major contributor to shisha’s health risks.

Smoke-free nicotine products eliminate this risk entirely by removing combustion from the equation.
