Shisha and Secondhand Smoke: The Evidence

July 21, 2026Anders Signell

Shisha smoking does not only affect the person using the waterpipe. Public health authorities warn that shisha also exposes others nearby to harmful secondhand smoke.

This is especially relevant in social settings, cafés, and enclosed spaces.


What Is Secondhand Smoke?

Secondhand smoke is a mixture of smoke exhaled by the user and smoke released from burning tobacco or charcoal.

According to the World Health Organization (WHO) , secondhand smoke contains many of the same toxic substances inhaled by the smoker.


Secondhand Smoke From Shisha

Shisha produces large amounts of smoke due to:

  • Burning charcoal
  • Long session duration
  • Continuous smoke production

The CDC notes that exposure to secondhand smoke increases the risk of heart disease and respiratory problems.


Carbon Monoxide Exposure for Bystanders

Charcoal used in shisha produces carbon monoxide that accumulates in indoor spaces.

WHO reports that carbon monoxide exposure is not limited to the smoker and can affect anyone nearby, particularly in poorly ventilated environments.


Shisha Cafés and Enclosed Spaces

In cafés and social venues, secondhand exposure can be substantial.

Public health authorities warn that employees and non-smoking patrons may face prolonged exposure to harmful smoke and gases.


How Smoke-Free Alternatives Change the Equation

Smoke-free nicotine products such as nicotine pouches do not produce secondhand smoke.

Vaping products also avoid combustion and do not release sidestream smoke in the same way as shisha or cigarettes.

According to the Royal College of Physicians , eliminating smoke greatly reduces risk to bystanders.


Frequently Asked Questions

Is secondhand shisha smoke dangerous?

Yes. It contains toxic substances that can harm non-smokers.

Does ventilation remove secondhand smoke risk?

Ventilation can reduce but not eliminate exposure.

Do nicotine pouches affect bystanders?

No. Nicotine pouches do not produce smoke or aerosol.


Conclusion

Public health evidence shows that shisha smoking poses risks not only to users but also to people nearby through secondhand smoke and carbon monoxide exposure.

Smoke-free alternatives eliminate this risk entirely by removing smoke and combustion from the environment.
