Do vapes contain nicotine, and can nicotine-free labels be trusted?
Many vapes contain dependence-forming nicotine, with concentrations varying between products. Nicotine has been found in some products marketed as nicotine-free. Its absence would not make the aerosol harmless, because other substances may affect respiratory health.

Flavour does not reveal composition
A sweet flavour or mild smell does not show what is in the liquid or how much is inhaled. Devices and liquids vary. Nicotine salts may allow substantial intake with less harshness, so one concentration range cannot describe every product.
Children and people who do not smoke
Nicotine can affect adolescent brain development and cause dependence. Non-smokers should not start vaping, and colourful packaging or marketing claims do not establish safety. Keep liquids away from children and animals to prevent swallowing or accidental exposure.
If you want to stop
Discuss cravings and support options with a professional, including the product and how it is used. Do not rely on unknown liquids to reduce nicotine. Breathlessness or chest pain after use needs assessment. If a child swallows vape liquid, obtain urgent medical or poison-centre advice immediately.
