Characterisation of young people known to Child & Adolescent Mental Health Services (CAMHS) who use substance and exploration of the impact of ADHD and adversity on substance use

This project will look at if adolescents with a psychiatric ADHD diagnosis are more likely to use drugs and alcohol than their peers and see if experiences of hardship in childhood change that relationship
