Here I present information on the variety of risk factors that predispose children and teens to later antisocial activities and drug use disorders. Approximately 25-45% of children with ADHD develop antisocial behavior by adolescence or adulthood and about 25%+ go on to develop substance use problems. That risk is further heightened if the person with ADHD also has a history of antisocial activities. This video explains all the risk factors at play across development to bring about these problems and also what might be done about them.
