This cohort study assesses whether stimulant medication for attention-deficit/hyperactivity disorder is associated with later substance use after considering age and other confounding factors not previously studied.
Findings: In this cohort study of 547 children initially treated in a randomized clinical trial for ADHD and assessed repeatedly to adulthood, comprehensive analyses did not support an association between stimulant treatment and adolescent or adulthood substance use or substance use disorder.
Meaning: This study found no evidence that stimulant treatment, predominantly prescribed in childhood and adolescence, protects against or increases risk of later frequent use of alcohol, cigarettes, marijuana, or other substance use by a mean age of 25 years.
