WHO, Nicotine and Vaping: Why Context Matters in Public Health Messaging
Recent World Health Organization (WHO) social media messaging has again framed nicotine and e-cigarettes in a way that lacks essential scientific context. Statements that are technically true in isolation can still mislead in practice, especially when they blur the difference between smoking (combustion) and non-combustible nicotine products (such as vaping). This article sets out the UK evidence-led position and why wording matters.
Nicotine is addictive, but not the main driver of smoking-related harm
Nicotine is addictive. That part is not controversial. What is often lost in public messaging is that nicotine is not the primary cause of smoking-related cancer, heart disease, COPD and premature death. The overwhelming harm from smoking comes from inhaling the toxic products created by burning tobacco.
This distinction is fundamental to UK healthcare. It is why nicotine replacement therapies (NRT) such as patches, gum, lozenges and sprays are licensed and used within NHS stop smoking care. If nicotine itself were the main driver of smoking-related harm, these treatments would not be widely recommended and used.
Key point: Addiction risk matters, but so does the risk of disease. Public health decisions should be based on the full risk picture, including whether a smoker can move from high harm (smoking) to substantially lower harm (vaping or licensed NRT).
What UK public health bodies actually say about vaping
In the UK, major public health bodies have consistently taken an evidence-led harm reduction approach. The Royal College of Physicians concluded that vaping is unlikely to exceed around 5 percent of the harm of smoking, and that encouraging smokers who cannot quit to switch is in the interests of public health.
Public Health England’s evidence reviews (now continued under UK public health structures) have repeatedly found that vaping exposes users to substantially lower levels of toxicants than smoking and can support smoking cessation at population level.
NICE guidance supports the use of licensed stop smoking treatments, including NRT, and provides the framework used across UK stop smoking services.

“Harmful emissions” needs comparison to smoking
E-cigarettes are not risk-free and they do produce an aerosol. The crucial public health question is not whether a product is completely harmless, but whether it is substantially less harmful than the alternative.
UK evidence reviews have repeatedly concluded that toxicant exposure from vaping is far lower than from smoking because there is no combustion and therefore no tobacco smoke. Messaging that mentions “harmful emissions” without comparing the far higher harms of cigarette smoke can mislead smokers into thinking there is no meaningful difference.
Youth protection is essential, but should not mislead adult smokers
Preventing youth uptake is essential. Children and non-smokers should not vape. Nicotine exposure in adolescents is undesirable, and enforcement on underage sales must be robust.
However, public messaging must be capable of holding two truths at once: protecting young people and accurately communicating that adult smokers who switch from cigarettes to vaping substantially reduce their health risks. If smokers believe vaping is “just as bad”, many will simply keep smoking.
Vapour Central stance: We support strict age enforcement and responsible retail. Our focus is adult smokers who want to quit cigarettes or stay off cigarettes.
Practical, responsible advice for customers
- If you do not smoke, do not start vaping.
- If you smoke, switching fully to vaping is likely to significantly reduce harm compared with continuing to smoke.
- Use reputable products and avoid unknown sellers. Product quality and compliance matter.
- If your goal is to quit nicotine entirely, vaping can be used as a step-down tool, alongside licensed stop smoking support.
- Keep nicotine products away from children, and treat nicotine responsibly.
FAQ
Is nicotine harmful?
Nicotine is addictive and not risk-free. It is not the main cause of smoking-related cancers and disease, which are driven primarily by the toxic products of burning tobacco. This is why licensed nicotine medicines are used in the NHS.
Is vaping safe?
Nothing inhaled should be described as completely safe. UK evidence reviews consistently conclude vaping is substantially less harmful than smoking, and it can help adult smokers quit cigarettes.
Should young people vape?
No. Children and non-smokers should not vape. Age restrictions should be enforced and youth access should be prevented.
What is the UK approach compared with some global messaging?
The UK approach is harm reduction: moving adult smokers away from combustible tobacco products. This is supported by UK public health bodies and the wider stop smoking system.
