The Bottom Line: Roughly 9 in 10 of the adolescents studied were of Latinx or Black race/ethnicity, allowing for a more holistic view of ADHD medication use in these populations. After 4 years of follow-up, only about 30% of patients were still using their ADHD medication. In the case of pharmacological interventions—stimulants, mostly—parents and adolescents blamed side effects as the main reason for discontinuation.
