Montgomery County overdose data
Montgomery County publishes some of the most detailed local overdose data in the country, through the Community Overdose Action Team at Public Health Dayton and Montgomery County. The current picture:
- 149 accidental overdose deaths in 2025, preliminary, down roughly 12 percent from 2024
- 176 deaths in 2024, a 39 percent decline from 2023
- 74 percent below the 2017 peak of 566 deaths
- Four consecutive years of decline
- 76 percent of 2024 overdose deaths involved an opioid, and 69 percent involved illicit fentanyl
- 1,049 emergency department visits for overdose in 2024, down 25 percent from 1,402 the prior year
- 6,728 naloxone kits distributed to the public in 2024
Montgomery County overdose deaths by year, 2017 to 2025
| Year | Deaths | Note |
|---|---|---|
| 2017 | 566 | Peak year, carfentanil in the supply |
| 2018 | 291 | First decline since 2010 |
| 2019 | 288 | Roughly level |
| 2020 | 323 | Pandemic-era increase |
| 2021 | 337 | Post-2017 high |
| 2022 | 316 | Decline resumes |
| 2023 | 293 | Down 7 percent |
| 2024 | 176 | Down 39 percent |
| 2025 | 149 | Preliminary, down roughly 12 percent |
The 2025 figure is preliminary. County totals are revised as the coroner’s office finalizes each case, so the most recent year is always the least settled number in the series.
How Dayton became a national epicenter
In 2017, Montgomery County recorded one of the highest overdose death rates of any county in the United States. The coroner’s office ran out of storage capacity and rented refrigerated trailers. Local officials described it publicly as a mass casualty event.
Two factors made the county unusually vulnerable. Dayton sits at the junction of two major interstates, which put it on a direct trafficking corridor. And the local supply in 2016 and 2017 contained carfentanil, an analog roughly 100 times more potent than fentanyl and originally developed as a large animal tranquilizer. Carfentanil appeared in a substantial share of the county’s deaths during that period and largely disappeared from the local supply afterward.
What changed
The scale of the decline in Montgomery County is unusual enough that it has been studied as a model. No single factor explains it, and local officials are careful to say so, but several elements are consistently credited.
The Community Overdose Action Team brought more than 100 organizations into a coordinated response with shared data, rather than agencies working separately. Naloxone was distributed at saturation levels through Project DAWN and community programs. Law enforcement shifted emphasis toward diversion into treatment. Real-time surveillance let the county spot spikes in days rather than months.
Changes in the drug supply itself also played a role, including the disappearance of carfentanil and, according to some analysts, reduced fentanyl production upstream. This part is genuinely uncertain, and researchers disagree about how much credit belongs to intervention versus supply. That uncertainty is worth stating plainly rather than papering over, because it affects how durable the gains are.
What is in the drug supply now
Fentanyl remains dominant
Illicit fentanyl was involved in 69 percent of Montgomery County overdose deaths in 2024, and some form of opioid in 76 percent. Fentanyl is roughly 50 times more potent than heroin and is mixed into powders and pressed into counterfeit pills without any consistency, so the amount in any given dose is unpredictable.
Stimulants mixed with opioids
The clearest shift in the Dayton area is polysubstance exposure. Methamphetamine and cocaine are increasingly found alongside fentanyl, sometimes because they were deliberately combined and sometimes through contamination. People who use stimulants and do not consider themselves opioid users are dying of opioid overdoses. This is why naloxone matters for anyone using any illicit substance, not only opioids.
Xylazine
Xylazine, a veterinary sedative that is not an opioid, has moved through the Midwest supply. Naloxone does not reverse its sedative effects, but it should still be administered immediately in any suspected overdose because fentanyl is typically present alongside it. Xylazine exposure is also associated with severe skin wounds.
Detox, rapid detox, and what these terms mean
People searching for detox options in Dayton encounter several terms used loosely and sometimes interchangeably. They describe different things.
Detoxification is the process of clearing opioids from the body and managing the withdrawal that follows. It is a medical event, not a course of treatment, and it addresses physical dependence rather than the psychological and behavioral dimensions of substance use disorder.
Medically supervised withdrawal in a residential program means staff monitor the person through withdrawal, with varying levels of medical capability on site.
Inpatient medical detoxification takes place in a hospital or licensed medical facility, where a physician manages symptoms, monitors vital signs, and can respond to complications.
Anesthesia-assisted or rapid detox refers to procedures that accelerate withdrawal under sedation or anesthesia. These are performed in a small number of facilities nationally, not in the Dayton area, and they vary considerably in protocol, setting, and medical oversight. Anyone considering one should ask specific questions: what facility is the procedure performed in, is it an accredited hospital, what are the physician’s credentials, what monitoring happens during and after, what happens if a complication arises, and what follow-up care is included.
One point applies to every version of detox. Tolerance falls quickly once opioids clear the body, which means a return to a previously ordinary dose after detox can be fatal. Detox without a plan for what follows carries real risk, and that plan should be made with a physician before the process begins rather than after.

Frequently asked questions
How many overdose deaths were there in Dayton and Montgomery County in 2025?
Preliminary county data shows 149 accidental overdose deaths in Montgomery County in 2025, roughly 12 percent fewer than 2024 and the fourth consecutive annual decline. Preliminary figures are revised as the coroner’s office finalizes cases.
Is Dayton still the overdose capital of America?
No. That description came from 2017, when Montgomery County recorded 566 overdose deaths and one of the highest per-capita rates in the country. Deaths have fallen roughly 74 percent since then. The county still sees a meaningful number of overdose deaths, but it is no longer an outlier nationally and is frequently cited as an example of a successful local response.
What drug causes the most overdose deaths in Montgomery County?
Illicit fentanyl. It was involved in 69 percent of overdose deaths in 2024, with some opioid present in 76 percent. Fentanyl is increasingly found combined with methamphetamine or cocaine.
Are there rapid detox centers in Dayton, Ohio?
Anesthesia-assisted rapid detox is performed at a small number of facilities nationally, and there are none in the Dayton area. People considering the procedure generally travel. Before doing so, it is worth asking what facility the procedure takes place in, whether it is an accredited hospital, the credentials of the supervising physician, what monitoring is provided, and what follow-up care is included.
Does naloxone work on a fentanyl overdose?
Yes, though more than one dose is often needed because of fentanyl’s potency. Naloxone is available free through Project DAWN and other Montgomery County programs. Emergency services should be called in every case, even when the person appears to recover.
Why did overdose deaths fall so sharply in Montgomery County?
Local officials credit a coordinated response through the Community Overdose Action Team, widespread naloxone distribution, law enforcement diversion into treatment, and real-time data surveillance. Changes in the illicit supply, including the disappearance of carfentanil, also contributed. Researchers disagree about how the credit divides between intervention and supply changes.
What should I do if someone is overdosing?
Call 911 immediately. Administer naloxone if it is available, and give additional doses if there is no response. Stay with the person until help arrives. Ohio’s Good Samaritan law provides limited immunity from certain drug possession charges for people who seek emergency help in good faith during an overdose.
How we source this page
County and state overdose figures come from different reporting systems and will not always match. Montgomery County figures on this page come from the Montgomery County Coroner’s Office as reported through the Community Overdose Action Team, which counts accidental overdose deaths occurring in the county. Ohio Department of Health figures count unintentional overdose deaths among Ohio residents and use a different methodology, so state and county numbers are not directly additive.
Preliminary counts are labeled as such. They are revised as the coroner’s office completes toxicology and finalizes cause of death, which typically means the most recent year rises somewhat before settling.
