Nicotine Vapes Offer Smokers Best Chance of Quitting, Major Review Concludes

Smokers seeking to quit the habit have the strongest chance of success if they turn to regulated nicotine e-cigarettes, according to a major new review published by the Cochrane collaboration. The analysis, which examined 80 trials involving nearly 30,000 participants, found that nicotine vapes increased the quit rate by approximately 60 per cent, from six in every 100 smokers managing to stop to one in every ten. This puts them ahead of traditional aids such as nicotine patches, gum, and support plans, and they also outperformed non-nicotine vapes, although researchers suggest switching to the latter could assist in the final weaning process.

Dr Jamie Hartmann-Boyce, one of the report's authors, stressed that the findings apply exclusively to regulated vapes compliant with strict safety laws, not the unlicensed products that may contain illicit substances like spice or THC. "Unlicensed e-cigarettes are potentially dangerous, with issues including unstable batteries and harmful chemicals," she warned. "Anyone looking to use e-cigarettes to quit smoking should only purchase devices that have been tested and approved by their country's regulatory body." The review found no evidence of increased risk of serious harm from using regulated e-cigarettes to quit, though it acknowledged that the long-term risks of vaping are not yet entirely clear.

The findings come at a time when the popularity of vaping in the UK has reached a notable milestone. Official figures now show that more over-16s use vapes or e-cigarettes than smoke cigarettes, with approximately 5.4 million people using vapes daily or occasionally, compared to 5.3 million who smoke. Experts, including the charity Action on Smoking and Health, have pointed to the stark contrast in health outcomes, noting that around two in three people who smoke long-term will die from a tobacco-related illness. According to the World Health Organization, smoking remains the leading cause of preventable disease and death, killing over seven million people annually.

Despite the promising data on vaping as a cessation tool, the NHS maintains a cautious stance, advising that children and non-smokers should never vape. Doctors have expressed concern that vaping could lead to health harms in young people and have called for measures to make the devices "less attractive" to them. The review's authors note that while nicotine vapes may also prove more effective than the new anti-smoking pill cytisine, which the NHS has begun to roll out, further research is needed to confirm this.

Almost every local NHS stop smoking service now provides vapes or other support to help people quit. Quitting smoking, whether through vaping or other means, significantly reduces the risk of serious illnesses such as heart disease, lung cancer, and stroke. The review serves as a significant contribution to the evidence base, offering a clear verdict for policymakers and clinicians: for adults who smoke, regulated nicotine vapes represent the most effective tool available to break the addiction.
