* Results: A total of 5 RCTs (n=3,253) were included. Compared with conventional smoking cessation therapies, the use of nicotine e-cigarettes was associated with an increase in abstinence, defined by the most rigorous criterion of abstinence reported (RR: 1.77; 95% CI: 1.29-2.44). Nicotine e-cigarettes also increased abstinence (defined by the most rigorous criterion) compared to non-nicotine e-cigarettes (RR: 1.56; 95% CI: 1.13-2.15). The incidence of death or SAEs was low across all trials at maximum follow-up. | * Results: A total of 5 RCTs (n=3,253) were included.

===2023: [https://www.sciencedirect.com/science/article/pii/S221133552300092X An examination of quitting smoking as a reason for vaping by the type of nicotine vaping device used most often among adults who smoke and vape: Findings from the Canada, England and the United States 2020 ITC Smoking and Vaping Survey]=== | |||
*In 2020, most adults who used NVPs and smoked cigarettes reported usually using either cartridge/pod or tank device types which were associated with greater odds of use to help with smoking cessation, compared to disposables. However, when we assessed this relationship separately within each country, significant associations were found in England and Canada, but not in the US. Adults who were vaping daily were more likely to report vaping to quit smoking, with the majority using tanks most often. | |||
