Europe: the WHO steps up its criticism of vaping

On 26 February 2026, the European regional office of the World Health Organization (WHO) published a statement that reopens the controversy around the electronic cigarette. The WHO points to a double alarm signal: a Europe that would remain the region most affected by smoking by 2030, and a worrying rise in vaping among teenagers. As a result, the organisation is calling on states to regulate vaping “like tobacco”, with strong measures on flavours, advertising and where it may be used.

A WHO Europe statement that hardens the tone

In its media release of 26 February 2026, WHO Europe points out that the region (53 countries) could remain, if the trend does not change, the highest in the world for smoking prevalence by 2030. But the angle attracting most attention concerns what it calls a “generational” emergency: the rise of vaping among young people.

• Around 4 million teenagers (aged 13 to 15) are said to use tobacco products in the region.
• Vaping is said to reach an estimated average prevalence of 14.3% among 13 to 15-year-olds, presented as the highest in the world.
• Among adults, WHO Europe refers to 31.4 million users of electronic cigarettes.

Against that background, WHO Europe considers that regulation remains too “fragmented” and is pressing for stricter harmonisation.

What the WHO recommends: applying the “strong tools” of tobacco control to vaping

The message is clear: for WHO Europe, the electronic cigarette should no longer be simply a matter for vigilance, but a product to be governed at the same level as combustible tobacco. The organisation puts forward levers similar to those of tobacco control policies:

• Restrictions on advertising and marketing (including on social media).
• A ban on, or limits to, flavours considered particularly attractive to minors.
• Stronger checks and enforcement of the rules (age, sales, product compliance).
• Possible taxation measures and controls on nicotine.

The statement cites Belgium, Denmark and the Netherlands as examples of countries that have adopted measures judged firmer.

The European Code Against Cancer puts vaping in the same sentence as tobacco

In parallel, the European Code Against Cancer (5th edition), led by IARC/WHO and supported by the European Commission, has crossed a symbolic threshold: its first recommendation explicitly mentions vaping alongside tobacco.

“Do not smoke… do not use vaping products.”

That very direct wording reinforces the idea of a precautionary approach: as long as the long-term effects are not fully known, encouraging vaping at population level remains contested.

Vaping and cancer: where the science is solid, and where it is not yet

The subject is often simplified in public debate, when it in fact rests on different levels of evidence:

1. The presence of substances of concern in emissions (some compounds may be carcinogenic).
2. Biomarkers of exposure or of biological effects (inflammation, oxidative stress, signatures consistent with a risk).
3. Epidemiological data (the actual incidence of cancers among exclusive vapers over the long term).

On the first two levels, recent literature (2021-2026) tends to show that there is a biological risk that is not zero: measurable toxicants, metals, biomarkers. On the third level, however, direct evidence of an impact on cancer incidence, the data remain limited, largely for want of hindsight.

A crucial point: “exclusive use” versus dual use

Many studies are hard to interpret because they mix together:

• former smokers who have become vapers (with a smoking history),
• “dual users” (vaping and cigarettes),
• and exclusive vapers, who are rarer.

Dual use can blur the results and dilute the potential benefits of a complete switch.

The “puffs” and metals angle: a further source of concern

Disposable devices (often called “puffs”) have added new elements to the debate, in particular around the quality of components and the variability between products. Some scientific publications have pointed to higher emissions of toxic metals in certain models, with exposure that may increase over successive puffs, which feeds the arguments for targeted restrictions (disposables, tighter checks, technical standards).

Risk reduction versus tobacco control: two readings that collide

The hardening of the WHO Europe line highlights a classic tension:

• Priority 1: to cut smoking (and its deadly effects) drastically through potentially less harmful alternatives.
• Priority 2: to prevent young people from taking up nicotine and to stop “recreational” use from becoming normal.

Within that framework, WHO Europe takes on an extended tobacco control logic: the aim is to slow the spread of nicotine dependence in a new generation, by targeting what makes the products attractive (flavours, marketing, social media).

Advocates of risk reduction, on the other hand, put forward a central idea: for a smoker, the question is not “vaping or nothing” but “vaping rather than smoking”, particularly where the switch is complete.

What this could change in Europe

The February 2026 statement can be read as an attempt to align several levels of decision-making: WHO recommendations, European orientations (smoke-free and aerosol-free spaces, taxation, product directives) and national measures (flavours, advertising, disposables, checks).

Three implications stand out:

1. Protecting young people becomes the main driver (flavours, advertising, access).
2. Product quality and safety take a central place (standards, market surveillance, action against non-compliant products).
3. Taxation could become a more explicit public health lever, with debate about the balance between the price signal and the risk of an illicit market.

Conclusion: a complex subject, far from settled

The WHO Europe message is unambiguous: faced with the rise of vaping among teenagers, the organisation wants stronger regulation, as close as possible to that of tobacco. Scientifically, the current picture is also clear: biological signals exist, but direct evidence on the actual incidence of cancers among exclusive vapers is still lacking.

Between health caution and the logic of risk reduction for smokers, Europe is moving along a narrow ridge. And at this rate, the rules on the electronic cigarette should continue to change quickly in the months ahead.
