The purpose of this legislation, known as the Combating Illicit Xylazine Act, is to regulate the use of xylazine, a substance that has been increasingly misused and poses risks to public health and safety. The main objectives are to classify xylazine as a controlled substance, implement stricter regulations on its distribution and use, and address its illicit use in the United States. Key provisions of the Act include adding xylazine to Schedule III of the Controlled Substances Act, which means that it will be subject to specific regulations similar to other controlled substances.
