Vaping May Help Quitting Smoking, But Safety Questions Persist
A living Cochrane review of around 80 randomized trials (nearly 30,000 smokers) finds regulated nicotine e-cigarettes boost quit rates more than nicotine replacement therapies and non-nicotine vapes, adding about 4 extra quitters per 100 versus NRT and about 2 per 100 versus non-nicotine options. The evidence is rated high certainty for vaping’s relative effectiveness, and experts say regulated devices are substantially less harmful than smoking. However, the review does not answer whether people stay off nicotine or vaping long term, and warns about unlicensed devices, potential long-term and cancer risks, and the need for more rigorous safety data. Funding came from Cancer Research UK, the NIH/NCI, and the FDA Center for Tobacco Products; published in Cochrane Database.
