Substance Use Statistics

Substance use remains a leading cause of preventable harm, with tobacco smoking causing 8.71 million deaths globally in 2019 and alcohol and drug use together accounting for 5.1% of all deaths. This page connects those global burdens to the pathways behind them, including opioid use disorders and the rising stakes of injection related risk, while also contrasting how use patterns and treatment access look today.
