E-cigarette Usage Is associated With Increased Past-12-Month quit attempts and Successful Smoking Cessation in Two US Population-Based Surveys.

Introduction:
This text is a summary of a research study examining the relationship between e-cigarette use and smoking cessation in the United States. The study uses data from two large, nationally representative surveys to analyze trends in smoking behaviors and the impact of e-cigarette use on quit attempts and cessation rates among adults aged 25-44.

Key Points:

* The study found that past-12-month quit attempts and smoking cessation significantly increased in recent years compared to 2006.
* Current e-cigarette use was associated with higher quit attempts and greater smoking cessation.
* The positive effects of e-cigarette use on quit attempts and cessation were strongest in everyday smokers.
* The study adjusts for demographic shifts in the US population and controls for various factors that may affect smoking behaviors.
* The data is analyzed using survey procedures and weighted to produce nationally representative estimates and to account for complex sample design.
* The study includes data from the National health Interview Survey from 2006 to 2016 and the Tobacco Use Supplement to the Current Population Survey in 2006-2007, 2010-2011, and 2014-2015.
* Data on e-cigarette use was available in the 2014-2016 NhIS and 2014-2015 TUS-CPS surveys.

Main Message:
The main message of the study is that the use of e-cigarettes among established smokers is associated with a reduction in combustible cigarette use, rather than delaying quit attempts and decreasing smoking cessation. These findings suggest that e-cigarettes may be a useful tool for smoking cessation and have implications for future tobacco policy decisions. however, it is important to note that e-cigarette use is not without risks and further research is needed to fully understand the potential benefits and harms of e-cigarette use.
