Trends in various e-cigarette devices used by high school adolescents from 2017-2019.

Introduction:
This text provides an analysis of trends in e-cigarette device use among high school adolescents in the United States from 2017 to 2019. The study aims to compare rates of e-cigarette device use over time, examine changes in frequency of device use, and identify predictors of device use. The research was conducted through cross-sectional surveys distributed in four high schools in Connecticut.

Key Points:

* The study found that rates of using JUUL, disposables/cig-a-likes, and vape pens increased significantly from 2017 to 2019, while use of mods and other pod devices decreased.
* Over 59% of youth reported using more than one e-cigarette device in 2019.
* Over time, more youth were frequent users (using ≥20 out of 30 days) of disposable/cig-a-likes and JUUL devices.
* In multivariable models, first trying e-cigarettes at a younger age was associated with current use of disposable/cig-a-like, vape pens, mods, and other rechargeable pod devices.
* The study also found that high school adolescents who used e-cigarettes were more likely to use other tobacco products, such as cigarettes, cigars, and hookah.
* The researchers suggest that tobacco regulations designed to reduce youth use should consider various device types.

Main Message:
The study highlights the increasing popularity of e-cigarette device use among high school adolescents in the United States, specifically JUUL, disposables/cig-a-likes, and vape pens. The findings suggest that regulations aimed at reducing youth e-cigarette use should consider various device types and the factors associated with their use, such as age of first trying e-cigarettes and use of other tobacco products. The researchers emphasize the need for further research to inform effective interventions and policies to reduce e-cigarette use among adolescents.
