Association of e-cigarette advertising with e-cigarette and cigarette use among US adults.

Introduction:
This text provides an analysis of the association between e-cigarette advertising exposure and e-cigarette and cigarette use among U.S. adults. The study aims to estimate the strength of this association across different age groups and to determine whether e-cigarette advertising encourages adult smokers to quit. The summary will cover the study design, major findings, and the main message of the text.

Key Points:

* The study used data from the National Adult Tobacco Survey (NATS) and the Simmons National Consumer Study (NCS) to construct measures of e-cigarette advertisements on TV and in magazines.
* The relationship between advertisement measures and outcomes was estimated using logistic and Poisson regressions, controlling for sociodemographics, state cigarette taxes, and state and year fixed effects.
* Exposure to e-cigarette advertisements on TV was associated with increased awareness, ever use, and current use of e-cigarettes among all adults.
* Exposure to e-cigarette advertisements in magazines was associated with some e-cigarette-related behaviors, but these effects were substantially weaker than those for TV advertisements.
* Exposure to e-cigarette advertisements on TV and in magazines was associated with higher proportions of current cigarette smokers and increased consumption among smokers.
* The association between e-cigarette advertising exposure and cigarette use was stronger among adults aged 18-24 years and adults aged 45 years and older.
* The study did not find evidence that e-cigarette advertising encourages adult smokers to quit.

Main Message:
The study finds that greater exposure to e-cigarette advertising is associated with greater ever and current use of e-cigarettes among U.S. adults. The findings also suggest that e-cigarette advertising is linked to increased cigarette use and consumption, particularly among older adults. These results provide evidence to inform potential regulatory actions on e-cigarette advertising and whether to place stricter evidentiary standards on promoting e-cigarettes as a cessation aid.
