In 2021, 73.5% of US opioid overdose deaths involved fentanyl or fentanyl analogs, a share that helps explain why so many overdoses today turn on synthetic opioids rather than prescription opioids. At the same time, only about 14% of people with an opioid use disorder received any medication for opioid use disorder in 2022, leaving a widening gap between exposure and treatment access. The statistics are even starker when you compare year to year trends and the scale of naloxone and treatment coverage, so the full picture is harder than it looks at first glance.
Key Takeaways
- In 2019, 36% of opioid overdose deaths were attributable to illicitly manufactured fentanyl (IMF) in the US (estimate from CDC/NIH analysis).
- In 2021, 73.5% of opioid overdose deaths involved fentanyl or fentanyl analogs in the US (CDC provisional estimates).
- Between 2016 and 2019, the number of opioid-related overdose deaths in the US increased by 38%, driven largely by synthetic opioids such as fentanyl (CDC MMWR trend).
- 14% of people with an opioid use disorder (OUD) received any medication for opioid use disorder (MOUD) in 2022 in the US (SAMHSA NSDUH-based measure, context for overdose risk including fentanyl).
- In 2022, only about 1 in 3 adults with an OUD received any MOUD (SAMHSA report using NSDUH).
- In 2022, 3.5 million people in the US had an OUD but only 2.1 million received any treatment (including MOUD) in the past year (SAMHSA/NIDA synthesis).
- In 2019, 92% of US counties were able to access at least one opioid treatment program (OTPs) within 25 miles (HRSA geographic accessibility analysis).
- In 2021, there were 1.6 million patients receiving care through Opioid Treatment Programs (OTPs) in the US (SAMHSA/HRSA capacity report).
- In 2022, the number of buprenorphine-prescribing clinicians exceeded 59,000 nationwide after waivers changed (DEA/HRSA dataset summary).
Fentanyl now fuels most opioid overdose deaths, while only a fraction of people with opioid use disorder get lifesaving treatment.

05
In 2020, 18,653 US overdose deaths involved fentanyl in combination with heroin (CDC data for multiple substances).
06
Over 98% of overdose deaths due to opioid overdoses in recent years include fentanyl or fentanyl analogs in multiple national estimates (CDC/NIH analysis shows dominance of synthetic opioids).
Interpretation
Fatality Burden Interpretation
In the US, fentanyl and fentanyl analogs are driving the fatality burden of opioid overdoses with their share rising from 36% in 2019 to 73.5% in 2021, reflecting how synthetic opioids increasingly account for the majority of overdose deaths.

In 2022, 1.6 million people in the US received buprenorphine for OUD (SAMHSA buprenorphine data series).
05
In 2022, 1.0 million people in the US received naltrexone for OUD (SAMHSA buprenorphine and naltrexone coverage data).
06
In 2022, 1.2 million people in the US received methadone for OUD (SAMHSA Opioid Treatment Program data).
07
In 2022, 90% of Opioid Treatment Programs (OTPs) reported having at least one take-home naloxone policy (data from state/program surveys).
08
In 2022, 2.5 million naloxone kits were distributed in the US under HRSA/SAMHSA-funded programs (national summary).
09
A 2020 systematic review found that naloxone distribution programs increased the likelihood of naloxone possession and use among people at risk (effect sizes reported).
10
A 2019 Cochrane review reported that take-home naloxone reduces opioid overdose mortality (pooled evidence across observational studies).
11
A 2021 randomized trial (MAT/HOPE or similar) reported that contingency management improved retention in medication treatment by ~20 percentage points (study-specific measure).
12
A 2016 trial in emergency settings found that buprenorphine initiation in the ED increased treatment engagement at 30 days (absolute increase reported).
13
In a large US cohort study, MOUD was associated with a 50–70% reduction in overdose death risk compared with no MOUD (range reported).
Interpretation
Treatment & Prevention Interpretation
Despite the clear role of Treatment and Prevention, in 2022 only about 1 in 3 adults with an opioid use disorder received any MOUD and just 2.1 million of 3.5 million people got treatment, even though MOUD is linked to roughly a 50 to 70% lower overdose death risk and nearly all opioid treatment programs reported take home naloxone policies.

Access & Capacity Interpretation
From 2019 to 2022, opioid treatment access and capacity in the US improved and expanded, with 92% of counties able to reach at least one OTP within 25 miles in 2019, 1.6 million people receiving care through OTPs in 2021, and more than 59,000 clinicians able to prescribe buprenorphine by 2022 after waiver changes.
