Methadone Statistics

GITNUXREPORT 2026

Methadone Statistics

Synthetic opioid overdose deaths rose 22% from 2019 to 2020, while opioid use disorder reached 2.1 million people in the US in 2022, and benzodiazepine co use showed up in 56% of 2023 opioid overdose deaths. This page tracks why methadone remains central to opioid treatment and outcomes, from dispensing patterns and retention gains to mortality, overdose, and cost evidence.

Synthetic opioid overdoses jumped 22% in the United States from 2019 to 2020, even as opioid treatment programs increasingly rely on methadone as the most dispensed option. At the same time, nearly 1 in 100 U.S. adults reported misusing prescription opioids in 2022 and opioid deaths are now shaped heavily by synthetic opioids and dangerous co use patterns. This post pulls together the latest methadone related statistics, from treatment capacity and dosing policies to outcomes like overdose death, HIV and hepatitis C risk, and even cost effectiveness.
