Illinois SB3221 proposed to schedule xylazine as a Class III controlled substance with exemptions; stated effective date Jan 1, 2027 (bill text)

SB3221 (104th General Assembly) proposes adding xylazine as a Class III (Schedule III) controlled substance under the Illinois Controlled Substances Act while providing that xylazine is not considered a controlled substance in specified circumstances (exemptions for certain legitimate uses). The bill PDF text indicates an effective date of 2027-01-01. Organizations that handle xylazine (including veterinary and related regulated activities) should monitor because scheduling would impose controlled-substance controls unless an exemption applies.
