Electronic Cigarette Use and Smoking Abstinence in Japan: A Cross-Sectional Study of Quitting Methods
TLDR
For effective smoking cessation, e-cigarette use appears to have low efficacy among smokers in Japan, and follow-up studies are needed to assess the prospective association between e-cigarettes use and smoking cessation.
The effect of e-cigarettes on smoking cessation and cigarette smoking initiation: An evidence-based rapid review and meta-analysis
TLDR
Low certainty evidence suggests that e-cigarettes appear to be potentially effective for smoking cessation and the use of e-cigarette in adolescents may be associated with smoking initiation.
E-cigarettes and Smoking Cessation in Smokers With Chronic Conditions.
Role of e-cigarettes and pharmacotherapy during attempts to quit cigarette smoking: The PATH Study 2013-16
TLDR
Among US daily smokers who quit cigarettes in 2014–15, use of e-cigarettes in that attempt compared to approved cessation aids or no products showed similar abstinence rates 1–2 years later, robust to sensitivity analyses.
E-cigarette use and smoking reduction or cessation in the 2010/2011 TUS-CPS longitudinal cohort
TLDR
Among early adopters, ever-use of first generation e-cigarettes to aid quitting cigarette smoking was not associated with improved cessation or with reduced consumption, even among heavier smokers.
Cohort study of electronic cigarette use: effectiveness and safety at 24 months
TLDR
E-cigarette use alone might support tobacco quitters remaining abstinent from smoking, but dual use did not improve the likelihood of quitting tobacco or e-cigarettes, but may be helpful to reduce tobacco consumption.
Smoking cessation among US adults: use of e-cigarettes, including JUUL, and NRT use
TLDR
Few smokers in the US use e-cigarettes, and JUUL specifically, for cessation, and NRTs use is relatively low, suggesting all e- cigarettes should undergo FDA review to minimise recreational use and understand their cessation efficacy.
E-Cigarette Use, Perceptions, and Cigarette Smoking Intentions in a Community Sample of Young Adult Non-Daily Cigarette Smokers
TLDR
E-cigarette frequency was positively associated with perceiving e-cigarettes as less harmful than cigarettes and more positive e-cigarette expectancies and the combination of these findings suggests that, at least among non-daily smoking young adults, other factors may influence frequency of e- vaping more than harm reduction.

E-Cigarettes and Smoking Cessation: Evidence from a Systematic Review and Meta-Analysis
TLDR
Use of e-cigarettes is associated with smoking cessation and reduction, and more randomised controlled trials are needed to assess effectiveness against other cessation methods.
E-Cigarettes and Smoking Cessation: Insights and Cautions From a Secondary Analysis of Data From a Study of Online Treatment-Seeking Smokers.
TLDR
The magnitude and significance of the estimated association between e-cigarette use and cessation in this study were dependent upon the analytical approach and future research should employ better measures of patterns of and reasons for e- cigarette use, frequency of e-cigarettes use, and concurrent use of cessation aids.

TLDR
Daily use of electronic cigarettes for at least 1 month is strongly associated with quitting smoking at follow-up, and the underlying reasons for intensive versus intermittent use are investigated to shed light on the mechanisms underlying the associations between e-cigarette use, motivation to quit, and smoking cessation.
A longitudinal analysis of electronic cigarette use and smoking cessation.
TLDR
A longitudinal analysis of a national sample of current US smokers to determine whether e-cigarettes use predicted successful quitting, or reduced cigarette consumption, found that e-cigarette users were less likely to have quit at 7 months than non-users.
Use of E-Cigarettes Among Current Smokers: Associations Among Reasons for Use, Quit Intentions, and Current Tobacco Use.
TLDR
Nearly a quarter of smokers in this study reported e-cigarettes use, primarily motivated by intentions to quit or reduce smoking, which identifies a clinical and public health opportunity to re-engage smokers in cessation efforts.
Alternative tobacco product use and smoking cessation: a national study.
TLDR
Alternative tobacco products are attractive to smokers who want to quit smoking, but these data did not indicate that alternative tobacco products promote cessation.
Effect of an electronic nicotine delivery device (e-Cigarette) on smoking reduction and cessation: a prospective 6-month pilot study
TLDR
The use of e-Cigarette substantially decreased cigarette consumption without causing significant side effects in smokers not intending to quit, and perception and acceptance of the product was good.
Electronic cigarettes and conventional cigarette use among U.S. adolescents: a cross-sectional study.
TLDR
Use of e-cigarettes was associated with higher odds of ever or current cigarette smoking, higher chances of established smoking, high odds of planning to quit smoking among current smokers, and, among experimenters, lower odds of abstinence from conventional cigarettes.
