UK Doctors Review 81 Vaping Studies, Link E-Cigarettes To Breathing Problems And Nicotine Addiction In Kids

Britain's leading children's doctors just put a number on what a lot of parents already suspected: vaping isn't harmless, and it's hitting kids hard.

The Royal College of Paediatrics and Child Health (RCPCH) reviewed 81 studies covering more than 14,000 published articles on vaping among children and young people. The findings, published in the journal Archives of Disease in Childhood, are blunt. Vaping is linked to wheezing, coughing, bronchitis symptoms and asthma flare-ups. It's linked to anxiety, depression and panic disorder. It's linked to oral and dental damage including inflammation, ulcers and dry mouth. It's linked to sleep problems, eye irritation and allergies.

Babies weren't spared either. Researchers found evidence that infants born to mothers who vaped during pregnancy showed "more abnormal reflexes," "lower motor maturity," poorer self-regulation and higher risk of low weight gain, according to the RCPCH.

Professor Will Carroll, who co-authored the review, didn't soften it: "Vaping should not be seen as a harmless part of growing up. The evidence shows clear links with respiratory symptoms, nicotine dependence and subsequent cigarette smoking, while concerns about wider impacts on young people's health continue to grow." He's calling on the government to "make vaping less attractive and accessible to children."

Vaping is supposed to be the safer alternative to smoking for adults trying to quit. Nobody in this review disputes that. The problem is the same candy-colored, fruit-flavored products designed to help a 45-year-old quit Marlboros are exactly what's hooking 13-year-olds who never smoked a cigarette in their life.

The RCPCH says the evidence on cigarette "gateway" effects is strong: kids who vape are significantly more likely to pick up traditional cigarettes down the line, reversing decades of progress on youth smoking.

The numbers are not small

Roughly one in five 11-to-17-year-olds in Britain have tried vaping, according to a poll for Action on Smoking and Health (ASH) cited by the BBC. The Mirror cites Children's Society data putting current vaping at nearly one in ten secondary school pupils, with one in four 11-to-15-year-olds having tried it at some point. Vape use overtook cigarette smoking in the UK last year for the first time, with 5.5 million vapers versus 4.9 million smokers, according to the Daily Mail.

This isn't just a UK problem. In the U.S., federal figures show nearly 6% of middle and high school students, about 1.63 million kids, reported vaping in 2024, according to Breitbart. That's down from peak years, but e-cigarettes remain the most-used tobacco product among American teens, and nearly 9 in 10 of those kids choose flavored products.

Policy response, and where it's headed

The UK government already passed the Tobacco and Vapes Act, which bans cigarette sales for life to anyone born after January 1, 2009, and banned single-use vapes. In July, it launched a 12-week consultation on vape packaging and flavor names, aiming for plain packaging and simple descriptors like "apple" instead of dessert- or candy-inspired branding. Health Secretary James Murray said "the evidence is clear: there are too many young people" being drawn in, according to the Mirror.

The RCPCH says that's not enough. Dr. Mike McKean, the college's vice-president for policy, called the Act "an important step" but warned it "must not be seen as a one-and-done solution." Carroll wants the government to go beyond renaming flavors and actually restrict which flavors can be sold at all.

Vapes exist because cigarettes kill people, and e-cigarettes are widely regarded as less harmful than combustible tobacco for adults trying to quit. Banning flavors outright risks pushing adult smokers back toward cigarettes or toward an unregulated black market, the same argument that's shaped FDA policy in the United States. The FDA recently authorized its first fruit-flavored vapes for adult smokers after pressure from the vaping industry and, according to Breitbart, appeals directly to President Trump. An FDA memo acknowledged those fruit flavors aren't meaningfully better than tobacco-flavored vapes at helping people quit, which undercuts the case for allowing them at all if the harm-reduction benefit is marginal while the appeal to teenagers is obvious.

Dr. Scott Hadland of Mass General Brigham for Children put it plainly to Breitbart: "I worry this could erode the hard-won progress that brought teen vaping to its lowest level in roughly a decade."

None of the sources here identify a randomized controlled trial proving vaping causes depression, asthma, or the other conditions listed. Most of the evidence is observational and cross-sectional, meaning it shows association, not proof of direct causation in every case. The RCPCH review itself is careful to describe some findings as "emerging evidence" rather than settled fact, particularly on sleep, eye symptoms, and allergies. That distinction matters and the doctors involved make it themselves.

The UK's 12-week consultation on vape packaging is still open, and the RCPCH is pushing to get flavor limits added before it closes. Whether Parliament goes further than plain packaging and simple flavor names, actually banning categories of flavors outright, remains an open question the government hasn't answered.
