    In 2016, 5.9 million children were diagnosed with attention-deficit/hyperactivity disorder (ADHD) and 63% of them were taking ADHD medication. However, little causal evidence exists on the effectiveness of ADHD drugs in the long-run, particularly on academic achievement. I compile a unique data set using administrative health, school, and criminal records from South Carolina and use quasi-random assignment of patients to medical providers to estimate causal effects of ADHD medications on multiple aspects of children's wellbeing. The estimated effects are positive in health and behavioral domains, but I find no evidence supporting improved school performance. Only some of the benefits of ADHD medications that accrue to female patients, are experienced by male patients, suggesting overdiagnosis of boys. I further show evidence that at least some of this effect may be coming from mislabeling boys who have other mental health conditions.
