How is it Used?
Xylazine can be administered orally, injected, or inhaled. It is often used in veterinary medicine to sedate large animals such as horses and cattle. Illicit use of xylazine typically involves injecting the drug or inhaling the fumes from heated xylazine tablets.
What are the Effects?
Short-Term Effects:
The short-term effects of xylazine use can include sedation, dizziness, and nausea. Xylazine can also cause respiratory depression, which can be life-threatening. In some cases, xylazine can cause seizures, muscle twitching, and loss of consciousness.
Long-Term Effects:
There is limited information available on the long-term effects of xylazine use in humans. However, animal studies have suggested that prolonged use of xylazine can lead to physical and psychological dependence, as well as a range of physical health problems. These can include respiratory problems, liver and kidney damage, and cognitive impairment. Chronic use of xylazine can also lead to mood disturbances, such as depression and anxiety.

Legal Status
Xylazine is a veterinary sedative approved by the U.S. Food and Drug Administration (FDA) exclusively for animal use; it is not approved for human use. At the federal level, xylazine is not classified as a controlled substance under the Controlled Substances Act. However, due to its increasing misuse in combination with illicit drugs like fentanyl, some states have taken independent action to regulate it.
In Florida, xylazine is classified as a Schedule I controlled substance, reflecting concerns over its harmful effects on humans. This classification imposes strict regulations on its possession and distribution within the state.
Nationally, the FDA has implemented measures to curb the unlawful importation of xylazine, aiming to prevent its diversion for illicit purposes while ensuring its availability for legitimate veterinary applications.
Given the evolving legal landscape surrounding xylazine, it’s essential to stay informed about both federal and state regulations, as they may change in response to emerging public health concerns.
