Changes in the Patterns and Characteristics of Youth ENDS Use over Time.

Introduction:
This article reports on a study examining the factors associated with both short-term and long-term use of electronic nicotine delivery systems (ENDS) among youth. The study used an ecological momentary assessment (EMa) burst design to explore daily variability within adolescents over a two-week observation period and variability over time two years later. The contribution of device characteristics, motivations for use, contextual factors, and community factors to daily use occasions were explored.

Key Points:

* The study found that some youth who experiment with ENDS may only be doing so temporarily, as close to a quarter of participants ceased all tobacco use two years later.
* Regular continued use of ENDS was predicted by trying to quit using cigarettes, appealing flavors, and being in locations where cigarette use was prohibited.
* Factors that affected ENDS use two years later, but did not affect ENDS use at year one, included trying to quit smoking, appealing flavors, and being in locations where smoking was not allowed.
* The study suggests that tobacco policy might target ENDS use by prohibiting all tobacco use, including ENDS, in locations where smoking is already banned.

Main Message:
The study highlights the importance of understanding the factors that contribute to long-term ENDS use among youth. The findings suggest that while some youth may only be experimenting with ENDS, others may become regular users. Factors such as trying to quit smoking, appealing flavors, and being in locations where smoking is prohibited may contribute to continued ENDS use. These findings have implications for tobacco policy, suggesting that prohibiting all tobacco use, including ENDS, in locations where smoking is already banned may be an effective strategy for reducing youth ENDS use.
