Combating Illicit Xylazine Act

HR 1266, the Combating Illicit Xylazine Act, adds xylazine - a veterinary sedative increasingly found in illicit drug mixtures - to Schedule III of the Controlled Substances Act, regulating its use and trafficking. It directly affects veterinarians, animal owners, and manufacturers by allowing xylazine to be legally dispensed for animal use under specific veterinary prescriptions, while prohibiting non-veterinary human use. The bill includes transition periods (60 days for practitioners, 1 year for labeling) to ease compliance for manufacturers and practitioners, and requires the DEA and FDA to expedite necessary applications. It also mandates two congressional reports on xylazine's illicit use and trafficking patterns, and directs the Sentencing Commission to review penalties for offenses involving xylazine.
