A major new study confirms that e-cigarettes are more effective than nicotine patches and gum for quitting smoking but health experts are issuing urgent warnings about the serious risks these devices carry, particularly for young people and non-smokers.
The study, led by researchers at the University of Oxford and published in the journal Addiction, analyzed 14 systematic reviews conducted between 2014 and 2023. The findings were clear: nicotine e-cigarettes consistently outperform traditional Nicotine Replacement Therapies (NRT) such as patches and gum in helping smokers achieve abstinence.
A 2024 Cochrane review included in the analysis found that for every 100 smokers, an additional two to five peoplesuccessfully quit using e-cigarettes compared to conventional NRT methods a clinically meaningful difference that could impact millions globally.
Senior researcher Angela Difeng Wu of Oxford’s Nuffield Department of Primary Care Health Sciences was unequivocal: the evidence is clear and consistent e-cigarettes work for smoking cessation.
However, the health picture is far more complex. While e-cigarettes eliminate combustion the primary driver of tobacco-related cancers and respiratory disease they are far from harmless. A February 2026 study confirmed that e-cigarette users are still exposed to carcinogenic chemicals, even if at significantly lower levels than traditional smokers. Long-term effects on the lungs, cardiovascular system, and immune function remain insufficiently studied due to the products’ relatively short consumer history.
The most alarming health concern, however, centres on children. The World Health Organization estimates that at least 15 million children aged 13 to 15 are already vaping worldwide a generation being hooked on nicotine before adulthood. WHO’s Etienne Krug described e-cigarettes as “fuelling a new wave of nicotine addiction,” warning they risk reversing decades of hard-won progress in tobacco control.
The medical consensus is clear: e-cigarettes may be a legitimate cessation tool for existing smokers, but they must never be seen as safe and must be kept firmly out of the hands of young people.
