Prescription stimulants are effective at treating attention disorders in children and adolescents, but concerns have been raised that they could make a young person more vulnerable to developing later substance use disorders.

This suggests that treatment with ADHD medication does not affect (either negatively or positively) an individual’s risk for developing a substance use disorder.39
