E-cigarette devices used on school grounds [PDF]
Addictive Behaviors, 2020 Preliminary evidence suggests adolescents use e-cigarettes in school. However, little is known about the types of devices that are used in schools, where they are used, and who uses them. Knowledge about these issues is critical to inform school regulations.Cross-sectional surveys were conducted in 6 Connecticut high schools in 2019.
