Nicotine e-cigarettes help smokers quit more effectively than gums or patches, according to a University of Oxford study published in Addiction.
Researchers analyzed 14 systematic reviews from 2014 to 2023, including a 2024 Cochrane analysis showing 2 to 5 additional quitters per 100 users compared to nicotine replacement therapies.
Despite proven efficacy, experts warn e-cigarettes aren't risk-free. Long-term health impacts remain unclear, and exposure to carcinogens is still a concern.
The World Health Organization criticized the industry for targeting minors, citing over 15 million children aged 13-15 using e-cigarettes globally. WHO’s Etienne Krug warned of a new wave of youth nicotine addiction threatening public health gains.
