Cochrane review finds nicotine e‑cigarettes boost quit rates over patches and gum
The updated review reports about four extra quitters per 100 users compared with nicotine patches and gum.
By Felo News Desk · Published
An updated Cochrane living systematic review of 80 randomised trials involving 29,861 participants finds that regulated nicotine e‑cigarettes produce higher smoking‑cessation rates than nicotine‑replacement therapy (NRT) such as patches and gum, as well as than no support or behavioural programmes.
What happened
The review added nine new trials to its previous version. Across the pooled data, for every 100 people using nicotine e‑cigarettes, roughly four more quit smoking than those using NRT patches or gum. Compared with non‑nicotine cigarettes, e‑cigarettes yielded about two additional quitters per 100 participants. The analysis also showed higher quit rates than no support or behavioural support, though the authors noted lower confidence in that comparison because of potential bias in some studies.
What the report adds
High‑certainty evidence supports the superiority of e‑cigarettes over patches and gum, according to the Cochrane authors. The review found no evidence that using e‑cigarettes to quit increases the risk of serious harm, but it stressed that longer‑term data are still needed. The conclusions apply only to regulated, nicotine‑containing devices; unlicensed products may pose safety risks.
What was said
"We have very strong evidence that regulated nicotine e‑cigarettes are substantially less harmful than smoking," said Dr Jamie Hartmann‑Boyce, senior author of the review from the University of Massachusetts Amherst, as reported by ScienceDaily.
"Unlicensed e‑cigarettes are potentially dangerous, with issues including unstable batteries and harmful chemicals," he added, urging users to purchase devices approved by regulators such as the FDA or MHRA.
How it came about
The Cochrane team maintains a "living" systematic review, continually updating its analysis as new trials become available. This latest update incorporates nine additional studies, confirming earlier findings that e‑cigarettes can be an effective cessation aid when properly regulated.
