Is vaping safe, and is it less harmful than smoking cigarettes?
Vaping is not harmless and is not recommended for children or people who do not smoke. For an adult smoker, completely switching from cigarettes to a regulated product may reduce some harmful exposures, but does not remove risk, and long-term effects remain incompletely known.

Different from cigarettes does not mean harmless
Burning tobacco generates many toxins. Vaping does not use the same combustion process, but aerosol may contain nicotine, chemicals and harmful particles. Products vary, so safety cannot be assumed to be identical across liquids and devices.
Complete switching differs from dual use
NHS guidance discusses regulated vaping as an option for some adult smokers trying to quit. Continuing cigarettes alongside it maintains exposure to tobacco smoke. Local policies and availability differ; discuss nicotine replacement, approved medicines and behavioural support with a professional.
A practical decision
If you do not smoke, do not start. If vaping is part of a quit plan, work toward stopping cigarettes and eventually nicotine with support. Avoid unknown liquids or home modifications. Pregnancy needs specific advice, and chest pain or breathlessness after use warrants prompt assessment.
