What is Xylazine?
Xylazine
is a powerful veterinary tranquilizer that is being found mixed with the
nation’s illicit fentanyl supply, contributing to a worsening of the fentanyl
crisis. Xylazine
does not respond to naloxone (i.e., Narcan) since it’s not an opioid and for
this reason, xylazine-fentanyl mixtures are being associated with a rise in drug-related
deaths nationally. Xylazine use is also linked to serious skin abscesses and
skin ulcers. Xylazine is commonly referred to as “Tranq” on the streets.
While
xylazine-fentanyl mixtures have been identified in the Houston Metropolitan
Area, this threat has not become as prominent in the region as in other areas
of the country. Fortunately, only a small proportion of seized pills and powders
with fentanyl were found to contain xylazine in the Houston area in 2022.
Because the danger associated with the use of fentanyl-xylazine combinations is so high, important actions have been taken nationally in 2023 to combat this serious threat.
In March of 2023, the Drug Enforcement Administration issued a public safety alert about the sharp increase in the trafficking of fentanyl-xylazine drug mixtures and the heightened risk of fatal drug poisonings associated with their use.

In April of 2023, the Director of the Office of National Drug Policy (ONDCP) designated fentanyl adulterated with xylazine as a national emerging drug threat.

In July of 2023, the White House released the National Response Plan for Fentanyl Combined with Xylazine to address the growing threat. Its goal is to lower overdose deaths from the lethal combination by 15%.

In September of 2023, the Department of Homeland
Security and the Drug Enforcement Administration released a joint statement on
sources of xylazine.
