Relating to: listing of carfentanil under the Uniform Controlled Substances Act and providing a penalty.

SB 692 would add carfentanil - a powerful opioid used in veterinary medicine but dangerous to humans - to Wisconsin's list of controlled substances under the Uniform Controlled Substances Act. This change directly affects individuals who possess, distribute, or use carfentanil without authorization, subjecting them to existing penalties for controlled substance violations. The bill modifies the statute by renumbering the section that lists carfentanil as a Schedule I controlled substance, aligning it with other opioids. The measure is pending in the Senate Committee on Mental Health, Substance Abuse Prevention, Children and Families after being introduced in December 2025.
