What was done
A retrospective temporal analysis of US opioid overdose mortality from 1999 to 2024 was conducted using the CDC WONDER Multiple Cause-of-Death database. Opioid-related deaths among adults aged 25 years and older were identified using ICD-10 codes T40.0–T40.4 and T40.6. Mortality rates were calculated by year, sex, age, race/ethnicity, and US census region, and temporal trends were evaluated using Joinpoint regression to estimate annual percent changes.
What was found
A total of 806,765 opioid overdose deaths were identified. The age-adjusted mortality rate (AAMR) increased from 4.41 to 22.84 per 100,000 between 1999 and 2024. Men consistently had higher AAMRs than women (20.64 vs. 9.52). By race/ethnicity, the highest AAMRs were observed in non-Hispanic American Indian/Alaska Native (21.79), non-Hispanic White (18.07), and non-Hispanic Black (15.97) populations. Adults aged 35–44 years had the highest crude mortality rate (20.52 per 100,000). By US census region, the Northeast had the highest AAMR (18.09), followed by the Midwest (15.69), South (14.74), and West (13.09).
Why it matters
This 25-year national analysis demonstrates that opioid overdose mortality in US adults increased more than fivefold, highlighting persistent demographic and geographic disparities that can inform targeted harm-reduction and policy interventions.
Limits
The study relies on death certificate data, which is susceptible to misclassification and coding variability across jurisdictions and over time. The dataset was restricted to adults aged 25 years and older, excluding younger populations. Specific opioid subclasses (e.g., illicit fentanyl vs. prescription opioids) and quantitative annual percent change figures were not provided in the abstract.
