- Cochrane published an updated living systematic review of 80 randomized controlled trials (29,861 participants) finding nicotine e-cigarettes produced higher quit rates than nicotine patches and gum, with about 4 additional quitters per 100 people.
- Nicotine e-cigarettes also outperformed non-nicotine e-cigarettes (~2 additional quitters per 100) and showed higher quit rates than quitting with behavioral support or no support, though researchers had less confidence in the latter comparison due to potential study-design bias.
- The review found no evidence that using regulated e-cigarettes to quit smoking increased the risk of serious harm, though the authors emphasized longer-term research is still needed.
- The conclusions apply only to regulated, nicotine-containing e-cigarettes; illicit products and devices containing substances like THC may carry different risks, including unstable batteries and harmful chemicals, the authors warned.
- Dr. Jamie Hartmann-Boyce (University of Massachusetts Amherst, senior author) and Dr. Nicola Lindson (University of Oxford, lead author) characterized e-cigarettes as a "proven and viable option" for smokers who have not succeeded with other aids.
- WHO and other major health bodies continue to warn that e-cigarettes expose users to harmful chemicals, with concerns about nicotine addiction among children and young people and possible progression to tobacco use.
- The researchers view e-cigarettes as a transition tool, not a final endpoint, and are already working on a follow-up review of interventions to help people quit vaping entirely.
Why it matters: Smokers who have failed with patches or gum now have high-certainty Cochrane evidence — 80 trials, 29,861 participants — pointing to regulated e-cigarettes as a more effective alternative, yielding about 4 additional quitters per 100 versus NRT. The researchers are already drafting the next review: how to help people quit vaping, signaling a bridge-to-quit framing rather than a permanent switch.
