What Xylazine Is and Why This Veterinary Tranquilizer Known as “Tranq” Has Reshaped the Fentanyl Supply in Tennessee
Xylazine is an animal drug that was never meant for people. Veterinarians use it as a sedative and muscle relaxant, most often for large animals, and the FDA has only ever approved it for veterinary use. Over the last several years, though, it has been showing up in the illegal drug supply, mixed into fentanyl and sold on the street as “tranq” or “tranq dope.” Most of the people who encounter it never asked for it. They bought what they thought was fentanyl or a counterfeit pill, and the xylazine was already in it.
What makes xylazine such a stubborn problem is a combination of three things. It deepens and prolongs sedation on top of an opioid, which raises overdose risk. It is not an opioid, so naloxone does not reverse its effects. And with repeated use it is linked to a distinctive pattern of severe, sometimes disfiguring skin wounds. Together, those features have changed what addiction treatment in Tennessee has to be prepared to handle.
This guide explains what xylazine is, what Tennessee and national data show, why naloxone behaves differently here, why the wounds matter so much, and what real treatment involves. It is informational only and is not medical or legal advice.
| Xylazine at a glance | Detail |
|---|---|
| Drug class | Alpha-2 adrenergic agonist, a non-opioid sedative |
| Approved use | Veterinary only; not approved for humans |
| Federal status | Not a scheduled controlled substance; legislation pending |
| Common street names | “Tranq,” “tranq dope,” “zombie drug” |
| Usually found with | Fentanyl, sometimes heroin or cocaine |
| Signature harm | Severe skin wounds, with amputation risk |
How Xylazine Differs From Opioids and Why Naloxone Cannot Reverse Tranq Sedation Even During an Overdose
The most important thing to understand about xylazine is also the most counterintuitive. It is a central nervous system depressant, so it slows breathing, heart rate, and blood pressure, but it is not an opioid. Naloxone, the medication in Narcan, only works on opioid receptors. That means naloxone can reverse the fentanyl in a mixture and get someone breathing again, but it does nothing to the xylazine sedation layered underneath. There is no reversal agent approved for xylazine in humans.
Public health agencies, including the CDC and the DEA, are emphatic on one point despite that limitation: give naloxone anyway. The opioid is usually what stops a person’s breathing, and reversing it can be the difference between life and death. The person may not fully “wake up” the way they would from a pure opioid overdose, and that is expected. Naloxone is still the right first move.
| In a xylazine-fentanyl overdose | Reversed by naloxone? |
|---|---|
| Opioid-driven slowed or stopped breathing | Yes |
| Deep, prolonged xylazine sedation | No |
| Xylazine-lowered heart rate and blood pressure | No |
What Tennessee Department of Health Data Reveals About the Sharp Rise in Xylazine-Involved Overdose Deaths and Seizures
Tennessee has tracked this closely, and the state’s own data is sobering. A study from the Office of Informatics and Analytics at the Tennessee Department of Health, published in JAMA Network Open, identified 324 fatal xylazine-involved overdoses in Tennessee between January 2019 and December 2022, along with 14 nonfatal ones. The climb over that window was steep, and drug seizures involving xylazine rose even faster than deaths.
324 fatal xylazine-involved overdoses in Tennessee, 2019 to 2022.
352% increase in fatal xylazine-involved overdoses across that period.
1,836% increase in xylazine drug seizures over the same window.
Local numbers tell the same story. Metro Nashville recorded its first xylazine overdose death in the first half of 2020, and the Metro Public Health Department issued a public warning in 2023. One quirk worth knowing is that Tennessee’s standard annual overdose report has historically not even used the word “xylazine,” because the national coding system it relies on has no specific code for xylazine toxicity. That gap is part of why independent surveillance and testing matter so much.

What National CDC and DEA Data Show About the Spread of Fentanyl Adulterated With Xylazine Across the United States
Tennessee’s experience mirrors a national one. The DEA reports that it has seized xylazine-fentanyl mixtures in 48 of 50 states, and its laboratory system found that in 2022, roughly 23 percent of fentanyl powder and 7 percent of fentanyl pills it seized contained xylazine.
The mortality trend rose sharply too. Using its State Unintentional Drug Overdose Reporting System, the CDC found that the monthly share of fentanyl-involved deaths with xylazine detected climbed 276 percent, from about 2.9 percent to 10.9 percent, between January 2019 and June 2022, with the heaviest concentration in the Northeast. Because of that trajectory, the White House Office of National Drug Control Policy took a formal step that shaped the federal response.
Fentanyl adulterated with xylazine was formally designated an emerging threat to the United States.
The White House released a National Response Plan targeting fentanyl mixed with xylazine.
An implementation report reviewed the plan’s early progress across testing, treatment, and harm reduction.
Congress has considered the Combating Illicit Xylazine Act, which would restrict illicit xylazine while preserving veterinary access.
It is worth stating plainly that, as of 2026, xylazine is still not a federally scheduled controlled substance. That legal gap is one reason enforcement and tracking have lagged behind the drug’s spread. More detail on the class is available through the DEA’s Diversion Control Division xylazine page.
Why Xylazine Causes Severe Necrotic Skin Wounds and What That Means for Treatment and Recovery
The wounds are what set xylazine apart from almost every other drug in this conversation. People who use xylazine-adulterated drugs can develop severe skin ulcerations that, in the worst cases, progress to necrosis, the death of tissue, and can require amputation. Crucially, these wounds are not limited to injection sites; they can appear on parts of the body far from where a person injected, and even in people who did not inject at all. Researchers believe the mechanism involves constriction of small blood vessels that starves the skin of blood flow, though the full picture is still being studied.
This changes what recovery has to include. A person cannot always work on their substance use in a vacuum while an open, infected wound goes untreated. Good programs treat both at once, which is a genuine differentiator when choosing a facility.
What xylazine-complicated treatment often has to add.
Beyond standard addiction care, this can include wound care with regular dressing changes, evaluation for infection and sometimes an infectious-disease consult, and surgical referral in severe necrotic cases, all alongside the medications and therapy that treat the underlying opioid use disorder.
Recognizing a Xylazine-Involved Overdose and How to Respond When Naloxone Alone May Not Be Enough
Because xylazine travels with fentanyl, an overdose starts as an opioid overdose: unresponsiveness, very slow or stopped breathing, blue or gray lips, and pinpoint pupils. The xylazine adds deeper, longer sedation and a slower heart rate that naloxone will not touch.
If you suspect an overdose.
Call 911 immediately. Give naloxone and be ready to give more than one dose. Because naloxone cannot reverse xylazine, the person may keep breathing yet stay heavily sedated, so they still need emergency care. If they are not breathing normally, rescue breathing helps. Stay with them until help arrives. In Tennessee, a Good Samaritan law provides civil immunity for people who administer naloxone in good faith.
The practical shift is the same one clinicians have been repeating: restored breathing after naloxone is no longer the all-clear it used to be when xylazine is in the supply. Emergency responders need to know xylazine may be involved so they can provide the supportive care that its sedation requires.
Understanding Xylazine Dependence, Severe Withdrawal Symptoms, and the Case for Medically Supervised Detox
Repeated exposure to xylazine can produce its own dependence, layered on top of opioid dependence. Public health agencies describe a withdrawal that can include severe anxiety and agitation, on top of the familiar opioid withdrawal symptoms of muscle aches, sweating, nausea, insomnia, and cravings. For some people the anxiety and restlessness are the hardest part, and they can be intense enough to make an unsupervised attempt to quit unbearable and prone to relapse.
The general course tracks opioid withdrawal, but the added agitation is why medically supervised detox is the safer route. Doing it in a monitored setting means the distress can be managed rather than simply endured.

What Evidence-Based Treatment for Fentanyl and Xylazine Polysubstance Use Disorder Actually Involves
There is no standalone “xylazine rehab,” because the underlying condition is opioid use disorder driven by the fentanyl the xylazine is mixed into. Treatment rests on the same evidence-based foundation used for opioids: medications for opioid use disorder, often shortened to MOUD, combined with behavioral care. Buprenorphine and methadone reduce withdrawal and cravings and are the most effective tools for cutting overdose risk, while naltrexone can support relapse prevention after detox.
What xylazine adds is the need for integrated medical care. The best programs coordinate wound care, infection management, and sometimes surgical evaluation with addiction treatment, rather than treating them as separate problems in separate places. They also manage the agitation-heavy withdrawal, and they address co-occurring depression, anxiety, or trauma. A program that can only offer counseling, with no medical capability, is not equipped for this particular problem.
What Distinguishes a Luxury or Private Xylazine Rehab Facility in Tennessee From Standard Outpatient Care
For a substance whose complications are as medical as they are behavioral, the features that matter most in a luxury or private program are clinical, not cosmetic. The priorities are medical detox with monitoring, experienced management of medications for opioid use disorder, and the ability to coordinate wound and infection care. Private and luxury programs tend to add smaller caseloads, more one-on-one clinician time, private accommodations, and holistic therapies that help people stay in treatment long enough to heal, physically as well as from the addiction. Those comforts are worthwhile, but they should sit on top of medical capability, not stand in for it.
The levels of care below make up the standard continuum, and many people move through more than one as they stabilize.
| Level of care | What it typically involves | Often suited to |
|---|---|---|
| Medical detox | 24-hour monitoring, symptom management | Agitated or severe withdrawal |
| Residential inpatient | Live-in care, often with wound support | Significant dependence or wounds |
| Partial hospitalization | Full-day structure, home at night | Step-down after stabilization |
| Intensive outpatient | Several sessions weekly around work | Milder needs, strong support |
| Outpatient MOUD | Ongoing medication and counseling | Long-term maintenance |
Cost and setting vary across the state. If you are comparing premium options, our look at the most expensive luxury rehab facilities in Tennessee and our guide to the top cities for luxury detox, executive rehab, and premium inpatient treatment give a feel for what different levels of care cost and where they sit. Because this is opioid use disorder treatment, most plans that cover addiction care apply; our breakdown of luxury rehab in Tennessee accepted through insurance coverage explains how to check your benefits.
How to Verify the Accreditation, Licensing, and Clinical Credibility of a Luxury Xylazine Rehab Provider in Tennessee
Since “luxury” is not a regulated term, the marketing tells you little about clinical quality. A few verifiable markers do. Look for accreditation from the Joint Commission or CARF, both independent bodies that audit safety and outcomes. Confirm state licensing through the Tennessee Department of Mental Health and Substance Abuse Services. Ask plainly whether the program provides medical detox and prescribes medications for opioid use disorder.
For xylazine specifically, add one more line of questions: how the program handles wounds, whether it has on-site or closely coordinated wound and infection care, and how it manages agitation-heavy withdrawal. A facility that can speak clearly to those points is showing the kind of expertise this drug demands. Vague reassurance, pressure to commit on the spot, or reluctance to discuss medication and wound care are reasons to keep looking.
