U.S. Overdose Deaths Drop 27% in 2024

U.S. Drug overdose deaths fell by 27% in 2024, according to a new report from the Commonwealth Fund, which details a sharp decline. Preliminary data for 2025 indicates another meaningful decrease, though mortality remains high.

Epidemiologist Brandon Marshall of Brown University called the rapid decline unprecedented. He cautioned, however, that the nation is nowhere near out of this crisis. The report's author, senior research associate Evan Gumas, found no single cause after speaking with public health authorities from two dozen states and other countries.

Potential Drivers of the Decline

Every official Gumas interviewed agreed there was no one solution. They repeatedly pointed to a handful of initiatives: naloxone distribution and harm reduction, expanded access to medications for opioid use disorder, better treatment in and around prisons, and enhanced data infrastructure.

Wider availability of the overdose reversal drug naloxone is a key factor. Since 2022, federal opioid response funding required states to develop naloxone saturation plans. Virginia saw a 40% decrease in overdose deaths from 2023 to 2024 after implementing its plan. Maryland more than doubled its naloxone distribution between 2021 and 2025, using vending machines, EMS, and public safety programs. The state recorded a 25% decrease in overdose deaths from 2019 to 2024.

Sarah Wakeman, an addiction medicine physician at Mass General Hospital, said every single overdose death is really a failure, because no one should die from an opioid-related overdose when an antidote exists.

Improving Medication Access

Access to medications like methadone and buprenorphine is also improving. Gumas's report calls Medicaid expansion the single most influential lever for this access. Colorado's methadone clinics more than doubled from 25 to 54 in five years. New York saw similar growth. Swedish authorities told Gumas that a decade of expanding medication access contributed to about a 25% reduction in deaths since 2017.

Treatment access for incarcerated people is another cited factor. Substance use disorders are 12 times more common in prisons than in the general population. In New York prisons and jails, the use of opioid use disorder medications increased sevenfold between 2022 and 2025.

Other Factors and Future Threats

Other sobering factors may play a role. Wakeman noted that the high death rates of prior years may have reduced the size of the population at risk. The drug supply is also constantly changing, with the potency of fentanyl declining in recent years.

Overdose deaths decreased in every U.S. State in 2024 except South Dakota, which had three more deaths than the year before. The geographical variation was wide and largely unexplained. Marshall said more research is needed rapidly to tease apart what is going on, adding that the dominant hypothesis is that it is mostly a function of the drug supply.

While hopeful, experts do not assume the decline will continue. Provisional 2025 data suggests rates may have crept back up in Scotland, which has the world's second-highest overdose death rate after the U.S.

In the U.S., many fear progress is at risk. Marshall criticized the Trump administration, saying its funding decisions risk and compromise much of the progress made so far. The Substance Abuse and Mental Health Services Administration saw more than half its staff cut and roughly $2 billion in funding canceled in the administration's first year. An agency directive also warned against using federal funds for certain harm reduction supplies.

The biggest threat is looming Medicaid cuts. Researchers from Penn and Boston University estimated last year that these cuts would cause 156,000 people to lose access to opioid treatment, leading the overdose rate to double among that group. Gumas said these cuts are going to be pretty catastrophic in a lot of cases.
