1Whose health comes first: teenagers or adult smokers?
The same product can hurt one group and help another.
Supporters say vapes hook a new generation on nicotine. Opponents say they help smokers quit something far deadlier.

An e-cigarette, or vape, is a battery-powered device that heats a liquid into an aerosol that the user breathes in.5 Most contain nicotine, the drug in tobacco, which is highly addictive.12 Banning vaping can mean a total ban on sales, as in India, or a ban on certain kinds, such as flavored or disposable vapes.
Vapes became popular as a less harmful way for smokers to get nicotine. In 2015, Public Health England said “the current best estimate is that e-cigarettes are around 95% less harmful than smoking.”10 Then teenagers took them up. By 2019, 27.5% of American high school students were vaping.3
Countries have split. In 2023 the World Health Organization (WHO) counted 34 countries that ban the sale of e-cigarettes and 74 with no rules for them at all.4 India banned their production and sale in 2019, with up to a year in prison for a first offense.18 Since July 2024, Australia has allowed vapes to be sold only in pharmacies.15 WHO's Director-General, Tedros Adhanom Ghebreyesus, warns: “Kids are being recruited and trapped at an early age to use e-cigarettes and may get hooked to nicotine.”4
In the United States, vapes are legal for adults 21 and over, but each product needs authorization from the Food and Drug Administration (FDA), which had authorized 39 by July 2025.21 Youth vaping has fallen: 1.63 million middle and high school students (5.9%) vaped in 2024, down from 2.13 million the year before. Of those users, 87.6% chose flavored products.1 Among adults, use rose from 4.5% in 2019 to 6.5% in 2023.25
Safety is still argued over. In 2019 and early 2020, 2,807 Americans were hospitalized or died with a lung injury linked to vaping, and 68 of them died.6 Most had used vapes containing THC, the main drug in cannabis, bought from friends or dealers, and investigators found that vitamin E acetate, an additive, was “strongly linked” to the outbreak.7 The US National Academies of Sciences found in 2018 that the long-term health effects of vaping “are not yet clear.”11
Vapes can also help people stop smoking. A 2025 Cochrane review found that out of every 100 smokers given nicotine vapes, about 9 quit for at least six months, compared with about 6 given nicotine patches or gum.8 That matters because tobacco kills more than 7 million people every year.5
The debate turns on three questions. Whose health should come first: teenagers who might start vaping, or adult smokers who might quit with its help? Are vapes a gateway into smoking or a way out of it? And does a ban actually stop vaping, or does it hand the trade to criminals? In January 2024, the UK's prime minister, Rishi Sunak, explained why his government was banning disposable vapes: “As any parent or teacher knows, one of the most worrying trends at the moment is the rise in vaping among children.”13
Most vaping debates are won or lost on these four questions.
The same product can hurt one group and help another.
Both sides agree vapes are not harmless. They disagree about what to compare them with.
Vapes might lead people into smoking, or out of it.
A law on paper is not the same as a change on the street.
The US: vapes are legal for adults 21 and over, but only products the FDA has authorized may be sold, and it had authorized 39 by July 2025.21
Full bans: 34 countries ban the sale of e-cigarettes, including India, which banned their production, sale and advertising in 2019.418
Middle paths: the UK banned single-use vapes in 2025, and Australia sells vapes only through pharmacies.1415 In New Zealand, more adults now vape daily (11.1%) than smoke daily (6.9%).26
Debate tip: comparing countries is useful evidence on both sides. Pro can point to countries that ban vapes outright; Con can point to places where smoking fell as vaping rose, or where restrictions fed a black market.
