The World Health Organisation (WHO) has issued a statement calling for urgent action to control e-cigarettes to protect children, as well as non-smokers, and minimise health harms to the population. E-cigarettes as consumer products are not shown to be effective for quitting tobacco use at the population level. Instead, alarming evidence has emerged on adverse population health effects.

E-cigarettes have been allowed on the open market and aggressively marketed to young people. Thirty-four countries ban the sale of e-cigarettes, 88 countries have no minimum age at which e-cigarettes can be bought, and 74 countries have no regulations in place for these harmful products.

“Kids are being recruited and trapped at an early age to use e-cigarettes and may get hooked to nicotine," said Tedros Adhanom Ghebreyesus, WHO director-general. "I urge countries to implement strict measures to prevent uptake to protect their citizens, especially their children and young people.”

E-cigarettes with nicotine are highly addictive and are harmful to health. Whilst long-term health effects are not fully understood, it has been established that they generate toxic substances, some of which are known to cause cancer and some that increase the risk of heart and lung disorders. Use of e-cigarettes can also affect brain development and lead to learning disorders for young people. Fetal exposure to e-cigarettes can adversely affect the development of the fetus in pregnant women. Exposure to emissions from e-cigarettes also poses risks to bystanders.

Ruediger Krech, WHO director for health promotion, said “E-cigarettes target children through social media and influencers, with at least 16,000 flavours. Some of these products use cartoon characters and have sleek designs, which appeal to the younger generation. There is an alarming increase in the use of e-cigarettes among children and young people with rates exceeding adult use in many countries.”

Data collated from WHO regions suggests children 13–15 years old are using e-cigarettes at rates higher than adults. In Canada, the rate of e-cigarette use among 16–19-year-olds has doubled between 2017–2022, and in the UK, the number of young users has tripled in the past three years.

Even brief exposure to e-cigarette content on social media can be associated with increased intention to use these products, as well as more positive attitudes toward e-cigarettes. Studies consistently show that young people who use e-cigarettes are almost three times more likely to use cigarettes later in life.

The WHO says urgent measures are needed to prevent the uptake of e-cigarettes and counter nicotine addiction alongside a comprehensive approach to tobacco control and in light of national circumstances. It suggests the following measures:

  • Where countries ban the sale of e-cigarettes to strengthen implementation of the ban and continue monitoring and surveillance to support public health interventions and ensure strong enforcement; and
  • Where countries permit commercialisation (sale, importation, distribution and manufacture) of e-cigarettes as consumer products to ensure strong regulations to reduce their appeal and their harm to the population, including banning all flavours, limiting the concentration and quality of nicotine, and taxing them

Cessation strategies should be based on the best available evidence of efficacy, to go with other tobacco control measures and subject to monitoring and evaluation. Based on the current evidence, the WHO does not recommend that governments permit the sale of e-cigarettes as consumer products in pursuit of a cessation objective.

Any government pursuing a smoking cessation strategy using e-cigarettes should control the conditions under which the products are accessed to ensure appropriate clinical conditions and regulate the products as medicines (including requiring marketing authorisation as medicines), says WHO. The decision to pursue a smoking cessation objective, even in such a controlled form, should be made only after considering national circumstances, along with the risk of uptake and after exhausting other proven cessation strategies.
