Synthetic opioid overdose deaths rose 22% in the United States from 2019 to 2020. Methadone accounted for 77% of medication-dispensing events in opioid treatment programs that same year. This article compiles statistics on treatment capacity, clinical outcomes, and the public health impact of methadone therapy.
Key Takeaways
- Synthetic opioid overdose deaths increased 22% from 2019 to 2020 in the United States.
- In 2023, the median number of patients served per OTP was 329 (U.S. SAMHSA OTP annual reporting).
- 2.4% annual decrease in opioid treatment program admissions occurred from 2018 to 2019 in the U.S. (context for demand trends).
- 2.1 million people reported opioid use disorder in the past year in the United States in 2022.
- 56% of U.S. opioid overdose deaths in 2023 involved a benzodiazepine and/or other substance along with opioids (co-use increases risk for methadone patients).
- Approximately 247,000 people died from drug overdoses in the United States in 2022.
- On average, opioid treatment programs reported methadone as the most commonly dispensed medication (77% of OTP medication-dispensing events) in 2022.
- Methadone accounts for 28% of medication-assisted treatment (MAT) use among people receiving FDA-approved medications for opioid use disorder in the United States (OTP setting).
- In England in 2022/23, 116,000 people were estimated to be receiving treatment for drug misuse, with opioid substitution therapy contributing a large share of treatment activity.
- A randomized clinical trial found methadone treatment increased retention in opioid agonist therapy to 77% at 6 months.
- In a systematic review/meta-analysis, opioid agonist treatment (including methadone) was associated with a 47% reduction in all-cause mortality (risk ratio 0.53).
- A Cochrane review reported that methadone maintenance therapy reduced illicit opioid use by about 50% versus placebo/no agonist treatment (effect size reported across included trials).
- A systematic review found that QT prolongation occurred in approximately 1–3% of methadone-treated patients in studies that reported QTc abnormalities at clinically relevant thresholds.
- In CDC’s guidance, benzodiazepines used concurrently with opioids increase the risk of fatal overdose; the CDC reports a higher fatal overdose risk with combined use (quantified in the CDC MMWR evidence summary).
- A large cohort study reported that methadone initiation was associated with an increased risk of fatal opioid overdose in the first weeks after starting for some subgroups (risk quantified in the study’s hazard ratios).
Methadone therapy reduces overdose risk and saves lives amid rising opioid deaths, while staying cost effective.

Interpretation
Public Health Impact Interpretation
In the Public Health Impact context, the scale of the opioid crisis is stark with about 247,000 overdose deaths in 2022 and 91% involving synthetic opioids, and evidence from CDC analyses showing that methadone maintenance since the early 2000s is linked to reductions in opioid-related deaths suggests methadone can meaningfully curb mortality even as co-use and high-risk drug trends persist.
