E-cigarette devices used by high-school youth.

Introduction:
This text is a summary of a study examining the use of different types of e-cigarette devices among high school students. The study aims to inform targeted regulatory and prevention strategies to reduce youth e-cigarette use by understanding the kinds of devices being used by youth.

Key Points:

* The study was conducted among high school students in Connecticut in Spring 2017.
* The study found that youth primarily used advanced generation devices, such as vape-pens, mods, and pod devices like JUUL, and not cig-a-likes.
* Nicotine use was highest for JUUL, followed by mods, cig-a-likes, and vape pens.
* Use of multiple devices was common, but JUUL was the highest single use device.
* Users of all devices, except JUUL, used other tobacco products.
* Use of JUUL was associated with higher SES.
* The study also found that youth who used e-cigarettes are using a wide variety of devices and in many cases multiple devices.

Main Message:
The main message of the study is that targeted regulatory and prevention efforts are needed to lower youth e-cigarette use rates, particularly for devices such as JUUL that are popular among youth and often used for nicotine delivery. The study also highlights the importance of considering the use of multiple e-cigarette devices in these efforts.
