Real-world effectiveness of e-cigarettes when used to aid smoking cessation: a cross-sectional population study.

摘要

Among smokers who have attempted to stop without professional support, those who use e-cigarettes are more likely to report continued abstinence than those who used a licensed NRT product bought over-the-counter or no aid to cessation. This difference persists after adjusting for a range of smoker characteristics such as nicotine dependence.
