Drug Use Statistics

Despite 4.3% of adults worldwide using drugs in 2021, a staggering 86% of people who use drugs still do not get drug treatment. From 12.4 million people using amphetamine-type stimulants in 2023 to the US death toll of 81,806 overdoses in 2023, this page connects gaps in care to real health and economic costs.

In 2023, 81,806 people died from drug overdoses in the United States, even though 86% of people who use drugs do not receive drug treatment. At the same time, 14.0 million people aged 12 and older used illicit drugs in the US in 2022 and 12.4 million people globally used amphetamine type stimulants in the past year. How do you reconcile these gaps in use, treatment, and harm across regions and drug types.
