association of e-Cigarette Use With Discontinuation of Cigarette Smoking among adult Smokers Who Were Initially Never Planning to quit.

Introduction:
This text provides an analysis of a study examining the association between e-cigarette use and discontinuation of cigarette smoking among smokers who were initially not planning to quit. The study uses data from the Population assessment of Tobacco and health (PaTh) Study and includes adult daily cigarette smokers who were not using e-cigarettes and had no plans to ever quit smoking. The study evaluates the use of e-cigarettes as a potential factor in helping smokers to discontinue cigarette smoking.

Key Points:

* The study uses data from the Population assessment of Tobacco and health (PaTh) Study, which is a nationally representative, longitudinal cohort study of youth and adults in the US.
* The study includes adult daily cigarette smokers who were not using e-cigarettes and had no plans to ever quit smoking.
* The study uses generalized estimating equations to evaluate the association between time-varying e-cigarette use and time-varying cigarette discontinuation and discontinuation of daily cigarette smoking.
* The study found that daily e-cigarette use was associated with greater odds of cigarette discontinuation among smokers who initially had no plans to ever quit smoking.
* The study adjusted for demographic characteristics, cigarettes smoked per day, and wave pair.
* The study used the PaTh Study W5 all-waves weights to produce nationally representative estimates.
* The study found that 6.2% of the population discontinued cigarette smoking, and daily e-cigarette use was associated with an 8-fold greater odds of cigarette discontinuation compared with no e-cigarette use.

Main Message:
The main message of the text is that daily e-cigarette use was associated with greater odds of cigarette discontinuation among smokers who initially had no plans to ever quit smoking. This finding suggests that e-cigarettes may be a potential factor in helping smokers to discontinue cigarette smoking, even if they were not initially planning to quit. however, further research is needed to understand the causal mechanisms underlying this association, and to assess long-term patterns of subsequent relapse and requitting. additionally, the study highlights the importance of considering smokers who are not planning to quit when evaluating the risk-benefit potential of e-cigarettes for smoking cessation in the population.
