Combating Illicit Xylazine Act
This bill criminalizes the illicit use of xylazine. (Xylazine, also known as Tranq, is a sedative that is approved for use in animals. The Drug Enforcement Administration (DEA) has reported an increase in the trafficking of fentanyl mixed with xylazine.)
Specifically, the bill establishes criminal penalties for manufacturing, distributing, or dispensing, or possessing with intent to manufacture, distribute, or dispense, xylazine for illicit use (i.e., for use in humans) in accordance with the penalties for schedule III substances (up to 10 years imprisonment or, if death or serious bodily injury occurs, up to 15 years imprisonment, as well as criminal fines).
In addition, the DEA must coordinate with the Food and Drug Administration to report on the prevalence of the illicit use of xylazine, including associated supply chains. The bill also declares the illicit use of xylazine as an emerging drug threat.
