A new comprehensive evidence review led by researchers at the University of Oxford provides further strong support for the role of vaping in helping smokers quit combustible tobacco.
Published in the scientific journal Addiction, the study brings together findings from 14 systematic reviews conducted between 2014 and 2023, offering one of the most robust overviews of the current evidence base on smoking cessation.
Strongest Evidence to Date
The results are clear: nicotine-containing e-cigarettes are more effective for smoking cessation than traditional methods, including nicotine replacement therapies such as patches, gums, and lozenges.
When focusing specifically on the highest-quality evidence, the findings consistently favour vaping over other cessation approaches.
Dr. Angela Wu, one of the lead researchers, emphasized the clarity of the evidence:
“The evidence is clear and consistent… e-cigarettes are effective at helping people stop smoking.”
Consistent With Previous Research
These findings align with previous high-quality research, including well-established reviews from Cochrane Collaboration, which have repeatedly shown that nicotine e-cigarettes increase quit rates compared to traditional nicotine replacement therapies.
The growing body of evidence points in the same direction:
- Higher quit rates compared to NRT
- Lower relapse rates among those who switch
- Continued use can help prevent returning to smoking
- Implications for Public Health Policy
This latest Oxford-led review reinforces a key message: harm reduction works. For millions of adult smokers who struggle to quit, access to less harmful alternatives like vaping can make a decisive difference. Public health strategies that acknowledge this reality can accelerate progress in reducing smoking-related disease.
A Call for Evidence-Based Regulation
The implications for policymakers are clear. Regulation of nicotine products should be guided by scientific evidence and relative risk, not by perception or ideology. Treating fundamentally different products—combustible tobacco and smoke-free alternatives—in the same way risks undermining public health goals.
As the evidence base continues to grow, it is increasingly difficult to ignore the role that vaping can play in reducing smoking rates across Europe and beyond.
Conclusion
Dustin Dahlmann, President of IEVA: “The new Oxford review adds to a consistent and expanding body of research: Vaping is not risk-free—but it is a significantly more effective tool for smoking cessation than many traditional approaches. Ensuring that adult smokers have access to these alternatives, alongside clear and accurate information, remains essential for any effective tobacco control strategy.“
