Federal Government Declares Fentanyl Laced With Xylazine an ‘Emerging Threat’
The White House has named the veterinary tranquilizer xylazine as an “emerging threat” when it’s mixed with the powerful opioid fentanyl, noting that the combination is increasingly being used and triggering overdoses.
The decision to name the drug as such, announced Wednesday, is the first time in U.S. history that the federal government declared a substance to be an emerging threat, said Dr. Rahul Gupta, director of the Office of National Drug Control Policy, in a statement.
The Food and Drug Administration (FDA) approved xylazine for veterinary use more than 50 years ago, primarily used for sedation, anesthesia, muscle relaxation, and analgesia in horses, cows, cats, and other mammals. However, it’s never been approved for human use.
“As a physician, I am deeply troubled about the devastating impact of the fentanyl-xylazine combination … I am immensely concerned about what this threat means for the nation,” Gupta said in a statement released by the White House. “By declaring xylazine combined with fentanyl as an emerging threat, we are being proactive in our approach to save lives and creating new tools for public health and public safety officials and communities across the nation.”
Known as “tranq,” xylazine was found to be connected to around 800 drug deaths in the United States in 2020. By 2021, it was present in more than 3,000 fatalities, according to a report released last year from the Drug Enforcement Administration (DEA). The drug causes breathing and heart rates to slow down, sometimes to deadly levels, and causes skin abscesses and ulcers that can require amputation, leading some media outlets to describe it as a “zombie drug.”
Gupta told The Associated Press his office is requesting $11 million as part of its budget to develop a strategy to tackle the drug’s spread. Plans include developing an antidote, learning more about how it is introduced into illicit drug supplies so that can be disrupted, and looking into whether Congress should classify it as a controlled substance.
“This drug, which is an animal sedative, is being mixed with fentanyl and is being found in almost all 50 states now,” Gupta told CNN on Tuesday. “It’s become an important part for us to make sure that we’re declaring it an emerging threat.”
But Gupta told news outlets that the drug needs to be available for veterinary uses even amid crackdowns on the supply used by people. He also said systems to detect the drug and data about where it’s being used need to be improved.
The U.S. Centers for Disease Control and Prevention estimates that more than 107,000 people died from overdoses in the 12 months that ended Nov. 30, 2022. Before 2020, the number of overdose deaths had never topped 100,000.
Most of the deaths were linked to fentanyl and other synthetic opioids. Like xylazine, they’re often added to other drugs—and users don’t always know they’re getting them.
Earlier this year, the (DEA) issued a “public safety alert” about the increase in fentanyl and xylazine use. When combined, there’s a greater risk of an overdose, the agency said, noting that opioid-reversal agent Narcan doesn’t work.
“Xylazine and fentanyl drug mixtures place users at a higher risk of suffering a fatal drug poisoning,” said the DEA. “Because xylazine is not an opioid, naloxone (Narcan) does not reverse its effects. Still, experts always recommend administering naloxone if someone might be suffering a drug poisoning.”
The agency noted that the Sinaloa Cartel and Jalisco Cartel in Mexico “are primarily responsible for the vast majority of the fentanyl that is being trafficked in communities across the United States,” the agency said.
A separate warning issued by the FDA said that repeated exposure to the tranquilizer can lead to severe necrotic ulcerations, while the DEA said last month that users “can develop severe wounds, including necrosis—the rotting of human tissue—that may lead to amputation.”
In a recent report about the drug, the DEA said that xylazine is cheap and is used as an adulterant by drug dealers and traffickers to increase their profits on fentanyl and heroin sales. It added that while some people may actively seek out the drug, many opioid users aren’t aware of its presence.
“Xylazine is one of the contaminants in fentanyl, but there could be others,” Gupta also told CNN on Wednesday. “So, I think with the declaration of an emerging threat, we’re sending a clear message to producers and traffickers of illicit xylazine and illicit fentanyl that we’re going to respond quicker, we’re going to match the challenge of evolution of these drugs supply, and that we’re going to protect lives first and foremost.”
