Summary
Introduction:
This article examines the associations between home and workplace vaping restrictions and e-cigarette use, frequency of use, and exposure to environmental vape aerosol among adults in the U.S. The study used data from the 2018 Tobacco Use Supplement to the Current Population Survey.
Key Points:
* The study found that respondents with household vaping restrictions had lower odds of current e-cigarette use.
* Those with some household vaping restrictions had significantly fewer expected days of past-month e-cigarette use.
* Workers with full workplace vaping restrictions had lower odds of workplace environmental vape aerosol exposure.
* Home e-cigarette restrictions appear to have a stronger association with e-cigarette use behaviors than workplace restrictions.
* The study controlled for age, sex, race, employment status, income, education attainment, any tobacco product use, metropolitan status, and census division.
* The analysis adjusted for the differential probability of sample selection, nonresponse, and noncoverage using sampling weights.
* The study used multivariable logistic and zero-inflated Poisson regression to assess the associations.
Main Message:
The study suggests that vaping restrictions in homes are associated with lower prevalence and frequency of e-cigarette use among adults. Those in worksites with complete vaping bans are less likely to be exposed to environmental aerosol at work. However, home e-cigarette restrictions appear to have a stronger association with e-cigarette use behaviors than workplace restrictions. Further research is needed to assess the directionality of the relationship between e-cigarette use and restrictions in the workplace and in private homes, as well as dual-use of cigarettes and e-cigarettes.
