Nicotine vapes best chance to quit smoking, major review finds

Nicotine‑based e‑cigarettes have emerged as the most effective tool for quitting smoking, according to a comprehensive Cochrane review that examined 80 large‑scale trials involving nearly 30,000 participants. The analysis found that people using nicotine vapes were about 60 % more likely to stop smoking than those relying on traditional nicotine‑replacement therapies such as patches, gum or pills, raising quit rates from roughly six per 100 smokers to ten per 100. Vapes also outperformed non‑nicotine e‑cigarettes, and early evidence suggests they may be more successful than the newly introduced anti‑smoking medication cytisine, although further research is required. The review focused exclusively on regulated devices that meet strict safety standards, excluding unlicensed products that could contain harmful substances.

The findings carry significant public‑health implications, especially in the United Kingdom where the prevalence of vaping now exceeds that of smoking among adults. Approximately 5.3 million people (10 % of the adult population) still smoke, while about 5.4 million use e‑cigarettes either daily or occasionally. Experts stress that, while vaping is not without risk, it is considerably safer than combustible tobacco. The review reported no evidence of increased serious harm from using regulated e‑cigarettes as a cessation aid, though long‑term health effects remain uncertain. Health authorities caution that unlicensed devices pose dangers such as unstable batteries and toxic chemicals, urging users to purchase only products approved by national regulators.

The report’s conclusions are already influencing cessation services across the NHS, where most local stop‑smoking programmes now offer regulated vapes alongside other support. Public‑health bodies continue to warn that vaping should never be taken up by children or non‑smokers, and they advocate for limiting appealing flavors and branding to deter youth uptake. As smoking remains the leading cause of preventable death worldwide—accounting for over seven million fatalities annually—enhancing access to the most effective quitting method could markedly reduce tobacco‑related morbidity and mortality.
