What to know
- The nonfatal drug overdose data on this dashboard come from CDC’s Drug Overdose Surveillance and Epidemiology (DOSE) system. DOSE captures electronic health record information in syndromic surveillance systems.
- Currently, 46 states and the District of Columbia share syndromic surveillance data with DOSE.
About this dashboard
Expand AllThe nonfatal drug overdose data on this dashboard come from CDC's Drug Overdose Surveillance and Epidemiology (DOSE) system, which captures electronic health record information in syndromic surveillance systems.
This dashboard represents the most up-to-date dataA that CDC's DOSE system has available and is updated shortly after new data are made available each month. CDC funds 46 states and the District of Columbia to share syndromic data with DOSE. Some data may be unavailable, including for states that are newly funded (indicated by "data not available") or if the state is unfunded (indicated by "unfunded state").
Data are presented as the monthly or annual percent change in the rate of emergency department (ED) visits involving suspected drug overdoses (e.g., ED visits involving drug overdoses divided by total ED visits and multiplied by 10,000). Important data considerations to help with interpretation of the data are detailed below the dashboard.

- Select a drug syndrome: Click on the box to select from a drop–down list of options.
- Select a state: Click on the box or the map to view overdose data by a specific state or overall.
- Compare month/year: Click on the box to select whether to compare by month or by year.
- Select timeframe for comparison: Use the date slider to select the adjacent month (e.g., February 2022 compared to January 2022) or previous year for comparison (e.g., January 2022 compared to January 2021).
- All visualizations will responsively adjust to your selections, including the summary data points; map; state table beneath the map; and changes over the past 6 months overall and by state, sex, and age.

* Data were collected for the time period beginning January 2018, but exclude several months during the onset of the COVID-19 pandemic (i.e., March 2020-August 2020). In some cases, the funded state did not provide CDC enough months of data to calculate percent change. Rates are suppressed when based on <20 overdoses, thus no percent change is available; for more information, please see: Healthy People 2010 Criteria for Data Suppression.
† To account for changes occurring across time, monthly and annual trends for the rate of ED visits involving suspected drug overdoses (e.g., ED visits involving drug overdoses divided by total ED visits and multiplied by 10,000) were analyzed overall and by U.S. state. Annual change, controlling for seasonal effects, was estimated as the change from a month in a given year to the same month in the following year (e.g., January 2018 to January 2019). Significance testing was conducted using chi-square tests.

- All data previously available on this dashboard (i.e., for the years 2018–2023) have been updated to reflect revisions in syndrome definitions. Datasets downloaded before June 2024 used older syndrome definitions, which have since been archived.
