The number of people receiving prescriptions for attention deficit/hyperactivity disorder (ADHD) in Ontario has risen more than 157 percent in less than a decade, with a marked increase among adults.
A study published in JAMA Network Open this week analyzed all prescriptions for stimulant drugs like Ritalin and Adderall that were dispensed in the province from 2015 to 2023. Researchers found there was a 157 percent rise in the overall annual new stimulant prescriptions by 2023 compared to 2015.
