Marin County Overdose Data
Overdose is the leading cause of death for Marin County residents aged 55 and under. Fentanyl is driving these overdoses and is associated with approximately 60% of overdose deaths in the county. The following data are intended to track trends and provide information for shared understanding and action across our county. OD Free Marin strives to prevent overdoses through data-driven strategies and community collaboration.
Non-Fatal Overdose
A non-fatal overdose is a sign of unsafe drug use and a risk for future fatal overdose. Tracking non-fatal overdose events provides valuable insights to guide prevention strategies. Outreach to overdose survivors is a proven approach to limiting mortality. Spikes in non-fatal overdoses may signal the presence of particularly potent substances in the drug supply, including fentanyl.

Data notes
Marin Health & Human Services (HHS) uses Emergency Medical Services (EMS) records from all 911 calls to identify suspected drug overdoses. A single overdose can include multiple substances. These records include both intentional and unintentional overdoses. Results are updated in the first week of each month.
* Data for the current year is complete as of the data refreshed date. ** Counts are not mutually exclusive, meaning one overdose event can include multiple types of drugs. *** Race/Ethnicity information became a mandatory field starting in 2021.
****Data recorded on 911 calls for gender only include Male or Female, limiting our understanding of the experience of those who may identify with other gender identities. We are sharing data collected that identifies the binary sex reported at the time of the 911 call as only Male or Female and thus recognize that this limits our understanding of those impacted who identify in other ways.
Fatal Overdose
OD Free Marin sees overdose deaths as preventable. We aim to reverse this trend by raising awareness, coordinating action, and directing resources to prevent overdose and save lives.

Data notes
Death investigations conducted by the Marin County Sheriff-Coroner for drug overdoses may take six months to a year, leading to delays in tallies of fatal events. 2023 data is now available with a few additional records under investigation and it presents an unchanged trend in the number of overdose deaths compared to 2022. These records include both intentional and unintentional overdoses. Results are updated the first week of each month.
* Counts are not mutually exclusive, meaning one overdose event can include multiple types of drugs.
**Data recorded on death certificates for gender only include Male or Female, limiting our understanding of the experience of those who may identify with other gender identities. We are sharing data collected that identifies the binary sex reported on the death certificate as only Male or Female and thus recognize that this limits our understanding of those impacted who identify in other ways.
Free Naloxone Distribution Dashboard
This dashboard shows naloxone kits given for free in Marin County to help prevent opioid overdose. Naloxone is a life-saving medicine that can reverse overdoses. It’s also available for purchase online and at pharmacies. We aim to make naloxone accessible without cost, raising awareness about its importance. OD Free Marin provides naloxone through vending machines, Naloxboxes, and community events. For free naloxone and training videos (in English and Spanish) visit our naloxone page.
Data Source: Naloxone vending machine data are provided by Behavioral Health and Recovery Services (BHRS), Department of Health and Human Services (HHS)
Treatment for Opioid Use Disorder: Buprenorphine and Methadone Prescriptions
Buprenorphine and methadone are medications that effectively treat Opioid Use Disorder (OUD) and reduce the risk of overdose. The fentanyl crisis has increased demand for these therapies, and improving access to treatment is an OD Free Marin goal. Learn more, including where to access treatment for opioid use disorder on our Medication Assisted Treatment (MAT) page.

Data notes
Buprenorphine prescriptions are reported by dispensing pharmacies to the California Prescription Drug Monitoring Program (PDMP). Marin County Department of Health and Human Services updates results here semi-annually.
Opioid Prescriptions, Marin County, 2008-2022
Safe and appropriate prescribing is a goal of OD Free Marin. Historically, opioid overprescribing fueled the opioid overdose epidemic. Tracking opioid prescriptions (by morphine equivalent) in Marin allows us to see trends in “opioid prescription burden,” or the negative health impacts of overprescribing over time. Additional details can be found on the California Opioid Overdose Surveillance Dashboard.
