The World Health Organisation portrays itself as the ultimate health authority. But its approach to vaping and other safer nicotine products has faced growing criticism for contradictions and missteps. Here are five major failures that have undermined global harm reduction efforts.
1. Equating vaping with smoking
Despite clear evidence that vaping carries far lower risk than smoking, the WHO continues to lump vapes and other “electronic nicotine delivery systems” in with cigarettes.
In its ‘Electronic cigarettes: call to action’ report, the WHO states: “E-cigarettes.. are harmful to health.” And in a 2023 news release, it claims that vapes “with nicotine are highly addictive and are harmful to health.. they generate toxic substances, some of which are known to cause cancer and some that increase the risk of heart and lung disorders.”
But there is no evidence that vaping causes cancer, and nicotine itself is not a carcinogen. The main culprits are the tar and thousands of chemicals released by burning tobacco. Studies show that vape aerosol contains far fewer and much lower levels of toxicants, making vaping a significantly less harmful alternative for smokers.
The WHO’s blanket statements fail to acknowledge the large body of evidence showing vaping carries far lower risk than smoking, implying an equivalence that could deter smokers from switching to safer alternatives.
2. Alarmist youth framing that ignores real patterns
The WHO has repeatedly warned that vapes are “fuelling a new wave of nicotine addiction,” claiming they “are marketed as harm reduction but, in reality, are hooking kids on nicotine earlier and risk undermining decades of progress.”
While youth vaping deserves attention, harm reduction experts point out that the WHO’s framing blurs key distinctions – between experimentation and regular use, and between teenage curiosity and adult smoking cessation. The result is public confusion and fear rather than clarity.
3. Endorsing overly restrictive bans that backfire
By promoting sweeping flavour bans, shop display restrictions and heavy taxation – without considering adult smokers who want to quit – the WHO risks pushing people back to cigarettes or into black markets.
Its one-size-fits-all approach fails to distinguish between policies that protect young people and those that make it harder for adults to stop smoking by switching to vaping.
4. Focusing on unknown risks over well-documented benefits
The WHO’s call for “urgent and strong decisive action.. to prevent uptake of e-cigarettes.. to protect children, as well as non-smokers” has shaped restrictive policies worldwide.
But this focus on hypothetical risks overlooks a well-established reality: smoking kills half its long-term users, while vaping exposes people to a fraction of those toxins.
By emphasising uncertainty over evidence, the WHO reinforces fear instead of supporting a practical path out of smoking.
5. Weak support for independent harm reduction research
As the most influential health body in the world, the WHO shapes national policy. But it has largely ignored independent research on safer nicotine alternatives.
UK experts have accused the agency of distorting science. “E-cigarettes are clearly less harmful than tobacco.. WHO misrepresents the available scientific evidence,” said Professor John Britton, a leading tobacco control researcher.
By sidelining harm reduction science, the WHO weakens the very evidence base it should be strengthening.
Why it matters – and what must change
The WHO’s misjudgments on vaping matter because they echo around the world. When it treats all nicotine products as equally dangerous, governments follow suit by imposing blunt bans that ignore harm reduction and keep smokers smoking.
If the WHO wants to maintain credibility, it must start reflecting science instead of fear. This means acknowledging the overwhelming evidence that safer nicotine products reduce harm, distinguishing clearly between smoking and vaping, and supporting research that helps people quit cigarettes for good.
Until then, the world’s leading health agency risks being on the wrong side of public health progress.
