What the Ontario Data Reveals

New research published in March 2026 reveals that the number of new monthly dispensations of stimulant medications to adults in Ontario more than doubled after the onset of the COVID-19 pandemic. By June 2024, approximately 1 in 50 adults aged 18-34 had been dispensed stimulants—a stunning increase that represents tens of thousands of new prescriptions.

The steepest growth occurred among young adults aged 18-24, a population that experienced unprecedented disruption to their education, work, and social environments during pandemic lockdowns. Researchers analyzing the Ontario population data noted the sharp rise began immediately after pandemic restrictions took effect and continued to climb through 2024.
