Dr. Sarah Helseth received a NIDA K23 grant for her study, entitled "Development and Preliminary Testing of an Adjunct Smartphone App to Reduce Marijuana use in Court-Involved, Non-Incarcerated Adolescents." This 5-year study will explore the mobile health needs and preferences of teens in the juvenile justice system, to build a new smartphone app to help teens cut down on their marijuana use. Congratulations!
