Classifies xylazine as Schedule III controlled dangerous substance under certain circumstances.

New Jersey's S 191 classifies xylazine - a sedative sometimes misused in illicit drugs - as a Schedule III controlled substance under state law, except when used by veterinarians for animal care. This means unauthorized possession, distribution, or use of xylazine would become a third-degree crime punishable by 3-5 years in prison and fines up to $35,000. The law directly affects individuals using xylazine outside veterinary contexts, including those misusing it with other drugs like fentanyl. Veterinarians remain exempt, allowing continued medical use for animals without criminal penalties.
