Illinois SB1553 proposed to add xylazine to Schedule III and add provisions/penalties related to manufacture/delivery/possession with intent (introduced 2025)

SB1553 (104th General Assembly) proposes amending the Illinois Controlled Substances Act to add xylazine to the Schedule III controlled substances list and to establish additional provisions addressing xylazine (including a veterinarian-related provision described in the introduced bill text, and penalty-related amendments tied to manufacture/delivery/possession-with-intent). If enacted, it would extend controlled-substance compliance obligations to xylazine in Illinois, affecting veterinary supply chains and any entities handling xylazine outside the scope of professional-practice exceptions.
