The World Health Organization (WHO) states that users of electronic cigarettes, such as vapes, should be warned about the health risks associated with the products they use.
The electronic cigarettes analyzed by the WHO are divided into two categories: electronic nicotine delivery systems (ENDS) and electronic non-nicotine delivery systems (ENNDS).
However, field findings differ. The WHO notes that most countries have not mandated health warnings for all types of products, both devices and e-liquids.
Specifically, 97 countries do not require warnings on nicotine-containing e-cigarette devices, and 91 countries do not require them on e-liquids.
Meanwhile, for non-nicotine e-cigarettes, 144 countries do not require warnings on devices and 143 countries do not require them on e-liquids.
"This data shows that regulatory measures, particularly in the form of health warnings, are still limited globally, especially for products that do not contain nicotine," the WHO wrote in its report, quoted on Tuesday, July 8, 2025.

Meanwhile, pictorial warnings are still rarely implemented on all types of products. The WHO notes that only 6 to 13 countries implement them.
Text-based warnings are more widely adopted for all types of products, particularly on nicotine-containing e-cigarette liquids (49 countries) and nicotine-containing e-cigarette devices (45 countries).
However, the good news is that the sale of these products is prohibited in a large number of countries, between 36 and 42 countries for all categories, both devices and e-liquids.
