Adolescent Substance Abuse Statistics

Recent 2023 figures show how quickly experimentation can escalate, including 9.0% of U.S. high school students reporting current inhalant use and 11.4% of adolescents 12 to 17 reporting past month marijuana use. The page ties these patterns to the real-world cost, including unmet treatment needs and major links to depression and violence, so you can see why effective prevention and early intervention matter before risk becomes routine.

In 2023, 11.4% of U.S. adolescents ages 12 to 17 reported past month marijuana use, even as a much larger share of teens with substance use still go without needed specialty care. And the pattern goes beyond substances, because past year use is linked to higher odds of depressive episodes and can spill into injuries, school discipline, and violence. By putting use, risk, and treatment gaps side by side, the dataset shows why adolescent substance abuse is harder to “catch” early than the headlines suggest.
