Association of Electronic Cigarette Regulations With Electronic Cigarette Use Among Adults in the United States.

Introduction:
This text provides an analysis of the association between US state regulations regarding electronic cigarettes (e-cigarettes) and current e-cigarette use among US adults. The study uses data from the Behavioral Risk Factor Surveillance System surveys from 2016 and 2017 to examine the association. The study hypothesizes that state laws regarding e-cigarettes may be associated with lower prevalence of e-cigarette use among adults across US states.

Key Points:

* The study uses data from the Behavioral Risk Factor Surveillance System surveys from 2016 and 2017.
* The study examines the association between US state regulations regarding e-cigarettes and current e-cigarette use among US adults.
* The study includes 894,997 adults aged 18 years or older with data on state residence and e-cigarette use available.
* The study considers participants as being exposed to the state law if they were living in the state where the state law regarding e-cigarette use was implemented no later than January 1 of the survey year.
* The study links state laws to each participant according to the year the survey was completed.
* The study adjusts for age, gender, race/ethnicity, education, family income, smoking status, alcohol intake, and physical activity.
* The study finds that state laws regarding e-cigarettes are associated with reduced e-cigarette use among US adults.

Main Message:
The study suggests that several state regulations regarding e-cigarettes may be associated with reduced current e-cigarette use among US adults. This finding highlights the potential impact of state regulations on public health and the importance of considering regulatory measures to reduce e-cigarette use. The study's results can inform policy-making and regulatory decisions regarding e-cigarettes at the state and federal levels.
