When addressing co-occurring disorders in teen drug treatment programs, it is crucial to take a holistic approach that considers both the substance abuse issues and any underlying mental health conditions. Integrated treatment programs that simultaneously address both aspects have been shown to be more effective in achieving long-term recovery for teens.

For example, a teen struggling with both substance abuse and depression may benefit from a treatment plan that includes therapy for both conditions, as well as support groups and educational workshops to address coping strategies and relapse prevention.
