Prescriptions for controlled stimulants among adolescents and young adults have increased significantly in the US since 2008. In a new research letter assessing the recent trends of controlled medication prescriptions for young Americans, a team of Boston investigators observed a substantial increase in stimulants among adolescents aged 13-18 years old and young adults aged 19-25 years old. Though the total prescriptions peaked in 2016, the trajectory of annual stimulant prescriptions in these age groups remained approximately twice greater than it was in 2008.
