Nearly One-Fourth of Eastern Ethiopian Adolescents are Current Psychoactive Substance Users: A School-Based Cross-Sectional Study.

One out of four adolescents was a current psychoactive substance user. Being male, substance availability, having substance-user friends, and being at younger age increased the psychoactive substance use rate in school adolescents in Eastern Ethiopia. The intervention that involves the schools' community, students' families, and executive bodies should be strengthened to overcome the substance use-related burdens among high school adolescent students.
