E-cigarette device type and combustible tobacco use: Results from a pooled analysis of 10,482 youth.

Introduction:
This text provides an analysis of data from 10,482 adolescents and young adults collected in 2018 to early 2020, examining the association between e-cigarette device use and combustible tobacco product use. The study aims to identify the specific e-cigarette devices that may place youth at higher risk for combustible tobacco product use.

Key Points:

* The study used data from 4 studies across Connecticut and California, with a total of 10,482 participants.
* Past-month e-cigarette use among high-school aged adolescents was 19.6% in 2020, and among young adults (18-23 years) was 9.3% in 2019.
* E-cigarette device types that appeal to youth include disposable devices, vape pens, tanks or mods, and pod-based systems.
* among past-month e-cigarette users, combustible tobacco use across all studies was 15.8%-61.5%.
* Pooled associations found that using multiple devices in the past month was associated with greater odds of combustible tobacco use (aOR 2.33, 95% CI: 1.74, 3.14).
* among past-month e-cigarette users, using disposable devices most frequently in the past month placed youth at high risk of combustible tobacco product use.
* The study did not determine whether the association between disposable devices and combustible tobacco product use is due to use of cigalikes or disposable pod devices.
* The findings suggest that use of any e-cigarettes, including pod-based systems, is associated with greater likelihood of combustible tobacco product use.

Main Message:
The study highlights the importance of understanding the association between e-cigarette device use and combustible tobacco product use among youth. The findings suggest that using disposable devices and multiple devices in the past month places youth at higher risk for combustible tobacco product use. The study supports the need for regulations targeting all e-cigarette devices to prevent e-cigarette use and combustible tobacco product use among youth.
