Makes xylazine a Schedule III controlled substance

SB 1724 reclassifies xylazine as a Schedule III controlled substance under Missouri law. This change subjects xylazine to state regulations governing controlled substances, including penalties for unauthorized possession or distribution. The bill amends Missouri's controlled substances schedule to include xylazine in Schedule III, which applies to substances with moderate abuse potential and accepted medical uses. This reclassification directly affects individuals who possess or distribute xylazine without authorization in Missouri. The bill does not alter federal scheduling of xylazine.
