Fentanyl Statistics and What They Mean
Fentanyl statistics describe several different things: deaths involving a drug, people living with opioid use disorder, overdose responses, and access to treatment. They cannot be used interchangeably. The most recent final national mortality figures below cover 2024, while a separate federal report identifies specific drugs in deaths through 2023.[1][2]
The decline in overdose deaths is encouraging. It does not erase the losses or predict any one person’s future. Research also points to practical ways to help, including access to naloxone and ongoing medication treatment for opioid use disorder.[3][4]
If someone may be overdosing, give naloxone if available and call 911. Stay with them until emergency help arrives. Do not wait to identify the drug or calculate the odds of survival.[5]
- 47,735 U.S. overdose deaths involved synthetic opioids other than methadone in 2024.[1] This category includes fentanyl and other drugs. It is not a fentanyl-only count.[1]
- The age-adjusted death rate for that category fell 35.6% from 2023 to 2024.[1] That is a change in a population-adjusted rate, not the percentage decline in the number of deaths.[1]
- Fentanyl ranked first among specific drugs in overdose deaths during 2017–2023 in a separate analysis of death-certificate text.[2]
- Time receiving methadone or buprenorphine was associated with lower mortality than time out of treatment in a large review of cohort studies.[6]
How Many People Die from Fentanyl and Other Opioids?
Final federal data recorded 79,384 drug overdose deaths in the United States in 2024, including 54,045 involving an opioid.[1] Deaths can involve more than one substance, so the opioid categories below overlap and must not be added together.[1]
The broad synthetic-opioid category is often used to describe the fentanyl era, but it also includes other drugs, such as tramadol.[1] A headline calling every death in that category a “fentanyl death” is more specific than these data support.
| Category | 2023 | 2024 |
|---|---|---|
| All drugs | 105,007[1] | 79,384[1] |
| Any opioid | 79,358[1] | 54,045[1] |
| Synthetic opioids other than methadone | 72,776[1] | 47,735[1] |
| Natural and semisynthetic opioids | 10,112[1] | 7,989[1] |
| Heroin | 3,984[1] | 2,743[1] |
| Methadone | 3,355[1] | 3,229[1] |
The age-adjusted rate for synthetic opioids other than methadone fell from 22.2 to 14.3 deaths per 100,000 people between 2023 and 2024, a 35.6% decline.[1] The overall drug overdose death rate fell from 31.3 to 23.1, a 26.2% decline.[1] These declines do not identify a single cause or establish that an individual drug product is safer.
Why a Fentanyl-Specific Report Has Different Numbers
A separate National Center for Health Statistics report examined the words written on death certificates, rather than only broad drug codes. Fentanyl ranked first in every year from 2017 through 2023.[2] Its death rate increased substantially over that period and then remained statistically stable between 2022 and 2023, while the heroin-involved rate declined.[2]
That report identified 73,297 fentanyl-involved deaths in 2023, or 68.9% of its overdose deaths.[2] Its fentanyl group includes related substances, such as analogs and metabolites. It also uses a later extraction from a database that continues to receive updates, which is why its counts differ from the fixed final annual series above.[2]
Do not splice the two reports into one fentanyl-only trend. For a comparison across years, use the same definition and series. Provisional figures can provide earlier signals, but they are subject to revision and should be labeled separately from final data.[2]
What Deaths Involving More Than One Drug Tell Us
In the death-certificate report, fentanyl was the most common additional drug among deaths involving each of the other leading drugs in 2023.[2] “Co-involvement” means that both drugs were identified as involved in a death. It does not establish which drug alone caused the death.[2]
| Deaths involving this drug | Also involved fentanyl | Share (%) |
|---|---|---|
| Xylazine | 6,033 of 6,096[2] | 99.0[2] |
| Heroin | 3,335 of 4,071[2] | 81.9[2] |
| Cocaine | 24,084 of 31,700[2] | 76.0[2] |
| Methamphetamine | 22,705 of 34,167[2] | 66.5[2] |
| Oxycodone | 2,002 of 4,142[2] | 48.3[2] |
The direction of a percentage matters. The xylazine row asks how often fentanyl was also involved in xylazine deaths. Looking in the opposite direction, 8.2% of fentanyl-involved deaths also involved xylazine.[2] Neither percentage measures the contents of all drugs sold.
Death records cannot distinguish every instance of intentional combined use from an unexpectedly contaminated product. Fentanyl, methamphetamine, and cocaine were the three most frequently identified drugs in unintentional overdose deaths in 2023, but that ranking alone does not prove fentanyl contamination of stimulant products.[2]
Other evidence does show that illicit fentanyl can be added to heroin, cocaine, methamphetamine, and counterfeit pills made to resemble prescription medicines.[7] Our fentanyl guide explains prescribed medical use, illicit supply, and addiction. The guides to heroin and prescription opioids explain those related risks.
Fentanyl test strips can provide information about a tested sample, but they cannot measure the fentanyl dose or establish that a drug is safe. Uneven mixing and false-negative results are possible. Keep naloxone available and avoid using alone even when a sample tests negative.[8]
Limits of the Mortality Data
Garnett and colleagues emphasize that reporting and toxicology testing vary across jurisdictions. A drug may be involved without being named on the certificate, and the analysis cannot assign each drug’s contribution to a death involving several substances.[2] This is why precise labels matter more than a dramatic headline.
Why Fentanyl Can Cause an Overdose
Fentanyl is a potent opioid that can slow or stop breathing. It has legitimate uses for severe pain, but most fentanyl contributing to the current overdose crisis is illegally made. Even a small amount can cause a fatal overdose, including when a person does not know a pill or another drug contains it.[7]
Potency means the amount needed to produce an effect. It does not translate into one universal fatal dose or an individual survival percentage. Appearance, taste, and smell cannot reliably tell someone whether another drug contains fentanyl.[7]
Computer models help researchers study overdose response. Baird and colleagues modeled how naloxone requirements could rise nonlinearly as fentanyl exposure increased.[9] Laffont and colleagues varied the time before an overdose-reversal medicine was given in a computer simulation.[10] These are simulations, not bedside dosing rules or a deadline after which help should be withheld.
What Naloxone Studies Show
Naloxone can reverse opioid overdose, including fentanyl overdose.[3] Study results depend on who received it, which events were reported, and whether the outcome was restored breathing, reported reversal, or survival. Those outcomes are related, but they are not identical.
| Study setting | Finding | How to interpret it |
|---|---|---|
| Programs serving people who use drugs | 98.3% survival, 95% confidence interval 97.5%–98.8%.[11] | Pooled reported outcomes in studies published during 2003–2018, not survival across all overdoses.[11] |
| Programs serving families or other community members | 95.0% survival, confidence interval 91.4%–97.1%.[11] | Different programs and circumstances, not a randomized comparison.[11] |
| Police naloxone programs | 92.4% survival, confidence interval 88.9%–94.8%.[11] | The difference does not establish that one responder type is less effective.[11] |
| Philadelphia smartphone-alert volunteers | Reported reversal in 71 of 74 naloxone-use cases, or 95.9%.[12] | A specific volunteer network in 2019–2020, not every bystander response.[12] |
A confidence interval describes the statistical uncertainty around an estimate. It does not predict an individual person’s outcome. Fischer and colleagues also identified a smaller group of studies published during 2018–2022 with similar survival findings.[11]
In the Philadelphia study, layperson intervention preceded emergency medical services by at least five minutes in 59.5% of naloxone-use cases.[12] The system linked witnesses to emergency services. It supports the value of prepared community responders, not replacing emergency care.
Missing Naloxone and Repeat Doses
Quinn and colleagues examined 33,084 fatal opioid-involved overdoses in 37 states and the District of Columbia in 2019.[13] They found no evidence of naloxone administration in 77.3%.[13] That means administration was not documented in the available records. It does not prove that naloxone was absent from every scene or explain every death.
A separate survey asked 125 U.S. adults about their most recent overdose response using 4 mg Narcan nasal spray.[14][15] Respondents reported using at least two doses in 78% of events and at least three in 30%.[14] These selected, self-reported events are not a universal dosing rule and do not establish that higher-strength products work better.
Historical Maryland poison-center reports also showed a change: mean prepacked naloxone doses rose from 2.12 mg to 3.63 mg during 2015–2017, while initial reversal rates declined from 82.1% to 76.4%.[16] The authors described the trend as likely multifactorial. It cannot isolate fentanyl as the cause.
That Maryland study detected fentanyl or an analog in 36 of 55 opioid-related deaths, or 65.5%.[16] This was a death subset within regional reported cases, not a national estimate. Additional naloxone from emergency personnel reversed toxicity in many patients whose initial response was insufficient.[16]
Use the person’s breathing and the product instructions, not a study percentage. Give naloxone and call 911. If normal breathing has not returned after 2 to 3 minutes, give another dose according to the product instructions.[3] Stay with the person until emergency help arrives.[5] See our fentanyl overdose response guide for the full steps.
Who the Data Describes
The fatal-overdose study found no evidence of naloxone administration in 87.3% of deaths among people age 65 or older and 87.5% among children younger than 15.[13] These are subgroups of fatal opioid cases, not the proportions of all older adults or children who lacked access. Fatal-case data alone cannot fully describe disparities in naloxone use.
Another important distinction is between using multiple drugs and having more than one substance use disorder. A disorder describes a pattern of use causing significant problems, not simply a positive drug test.[17] A review of 194 studies involving 77,212 people with opioid use disorder estimated that 59.5% had another current substance use disorder.[18]
| Other substance use disorder | Estimate | 95% confidence interval |
|---|---|---|
| Any non-opioid disorder | 59.5%[18] | 49.1%–69.5%[18] |
| Cocaine | 30.5%[18] | 23.0%–38.7%[18] |
| Alcohol | 27.1%[18] | 24.4%–30.0%[18] |
| Cannabis | 22.7%[18] | 19.0%–26.6%[18] |
The review found substantial variation across studies, settings, and countries.[18] These estimates are not a current U.S. census or proof of contaminated drugs. They support asking about the whole pattern of substance use so treatment can address co-occurring needs.[4]
Treatment Access and Outcomes
CDC reports that an estimated 6.1 million people age 12 or older had opioid use disorder in 2022.[19] This is a historical estimate covering opioids broadly, not a current count of fentanyl addiction.
A separate analysis estimated that 9,367,000 adults, or 3.7%, needed opioid use disorder treatment in 2022.[20] Its broader definition included people who met diagnostic criteria or received treatment during the past year. Some people continuing successful treatment no longer met the past-year symptom criteria.[20]
Among adults in that treatment-need group, 25.1% reported medication for opioid use disorder.[20] The medication measure included methadone, buprenorphine, and naltrexone. It was not limited to methadone or buprenorphine, and the household survey excluded people in institutions and people experiencing homelessness outside shelters.[20]
What Medication Studies Found
In a systematic review, 36 cohort studies involving 749,634 people with opioid dependence found an all-cause mortality rate ratio of 0.47 during opioid agonist treatment compared with time out of treatment.[6] The confidence interval was 0.42–0.53.[6] In plain language, the observed rate was about half as high.[6] This is an association, not a guaranteed personal benefit or a fentanyl-only estimate.
Opioid agonist treatment in that review meant methadone or buprenorphine.[6] These medications can reduce cravings and withdrawal, the symptoms that develop after opioid use is reduced or stopped.[17][4] Naltrexone blocks opioid effects and is another approved treatment, with different starting requirements.[4] A clinician can help select and start treatment based on the person’s needs.
| Who was studied | What happened | Important limit |
|---|---|---|
| 4,898 New Jersey Medicaid beneficiaries, ages 12–64, with an opioid overdose during 2015–2018.[21] | 19.6% had another opioid overdose within a year. Only 21.7% received medication for opioid use disorder during follow-up.[21] | In the heroin/synthetic-opioid subgroup, medication was associated with lower repeat-overdose hazard (hazard ratio 0.30, confidence interval 0.20–0.46). Observational association does not prove causation.[21] |
| 136,762 adult Medicare fee-for-service beneficiaries with a nonfatal drug overdose in 2020.[22] | 4.1% received medication for opioid use disorder and 6.2% filled a naloxone prescription in the following year.[22] | The starting overdoses involved drugs broadly, not only fentanyl or opioids. Prescription claims do not measure every way naloxone may be obtained.[22] |
A hazard is the rate at which an event occurs during follow-up among people who have not yet had it. A lower repeat-overdose hazard in one subgroup does not mean that treatment prevents the same percentage of overdoses in every population.
How Fentanyl Is Affecting Treatment Practice
In a conference survey of 91 addiction specialists, about 89% said high-potency synthetic opioids had changed treatment, and 86% reported changing their medication prescribing.[23] These are the views of that respondent group, not a survey of every clinician.
Sharma and colleagues compared 30 participants with fentanyl exposure against 103 participants with other opioid exposure in a study that gave participants scheduled morphine under research supervision.[24] The fentanyl group had more severe withdrawal on several measures and remained less stabilized over several days.[24] The study supports individualized withdrawal planning. It does not establish that everyone needs inpatient detox or will have the same course.
Our fentanyl withdrawal guide explains what to discuss with a clinician. Withdrawal management should connect to ongoing treatment. Detoxification means managing the period of withdrawal. Detoxification alone, without medication for opioid use disorder, is not recommended because of the risks of returning to use and overdose.[4]
Using the Numbers to Take a Next Step
The studies describe populations, not your worth or your future. You can use them to ask practical questions: Can I get naloxone today? Does this provider offer medication for opioid use disorder? How will they help with withdrawal and other substance use?
Ask a pharmacist or local health department about naloxone. Community programs may offer it free or at reduced cost.[3] For treatment referrals, call SAMHSA at 1-800-662-HELP (4357) or visit FindTreatment.gov.[7] For suicidal thoughts or a mental-health crisis, call or text 988. Suspected overdose requires 911.[7]
Our treatment centers directory can help you explore care options. Ask specifically about medications for opioid use disorder, follow-up, cost, and the level of care available. If you also want counseling, explore our online therapy resource.
Frequently asked questions
How Many People Die From Fentanyl and Opioids Each Year?
Final federal data counted 79,384 U.S. drug overdose deaths in 2024, including 54,045 involving any opioid and 47,735 involving synthetic opioids other than methadone.[1] The last category includes fentanyl but is not fentanyl-only. The categories overlap and should not be added together.
What Percentage of Overdose Deaths Involve Fentanyl?
A federal analysis of death-certificate text found fentanyl involved in 68.9% of its 2023 overdose deaths.[2] Its fentanyl group includes related substances, and the report uses a later database extraction than the fixed final annual mortality file. This percentage describes deaths, not the share of drugs sold that contain fentanyl.
How Many People Are Addicted to Opioids in the US?
CDC reports an estimated 6.1 million people age 12 or older had opioid use disorder in 2022.[19] A separate estimate of 9,367,000 adults needing treatment used a broader definition that also included people receiving treatment.[20] These are historical opioid-wide estimates, not current fentanyl-addiction counts. Opioid use disorder involves a pattern causing significant distress or impairment.[17]
Why Is Fentanyl So Much More Deadly Than Other Opioids?
Fentanyl is potent and can slow or stop breathing. Even a small amount can cause a fatal overdose. Illicit fentanyl may also be present unexpectedly in counterfeit pills or other drugs, and appearance cannot tell you whether it is there.[7] Mortality rankings do not establish one universal fatal dose or an individual risk percentage.
Is One Dose of Narcan Enough for a Fentanyl Overdose?
One dose may be enough, but another may be needed. Give naloxone and call 911. If normal breathing has not returned after 2 to 3 minutes, give another dose according to the product instructions.[3] Stay until emergency help arrives.[5] Study percentages are not dosing rules for an individual overdose.
Does Treatment for Fentanyl Addiction Actually Work?
Medication treatment can help. A review of cohort studies found about half the all-cause mortality rate during methadone or buprenorphine treatment compared with time out of treatment.[6] That is an observational association, not a fentanyl-specific guarantee. Treatment should be individualized, and withdrawal management should connect to ongoing care.[4]
How Do I Get Help for Myself or Someone Using Fentanyl?
For treatment referrals, call SAMHSA at 1-800-662-HELP (4357) or visit FindTreatment.gov.[7] Ask about medication for opioid use disorder and help managing withdrawal.[4] Our treatment centers directory offers another way to explore care. For a suspected overdose, give naloxone and call 911.[5]
