Emerging trends and innovations in the identification and management of drug use among adolescents and young adults.

One in four youths aged 12 to 17 years and more than half of young adults aged 18 to 25 years in the United States have used an illicit drug in their lifetime. A significant number progress to problematic use, and only 1 in 10 young people who meet criteria for dependence or abuse receive some form of treatment. Despite advances in the field, effectively intervening along the continuum of drug use involvement remains a challenge. In this article, we review the current epidemiology of illicit drug use by young people; describe recent advances in assessment, intervention and treatment; and highlight how technology can help overcome barriers to effective management of drug use among young people.
