Nature Medicine has published a significant author correction to the Global Burden of Disease Study, updating epidemiological estimates for substance use disorders across 204 countries from 1990 to 2023. The corrected dataset focuses on four major drug classes—amphetamines, cannabis, cocaine, and opioids—representing the primary substances of global health concern.
