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, 47 states and the District of Columbia share syndromic surveillance data with DOSE.
About this dashboard
The 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 47 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.

- 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 Datasets downloaded before June 2024 used older syndrome definitions, which have since been archived.
