No. Wisconsin classifies kratom as a Schedule I controlled substance, making possession, sale, or distribution illegal statewide as of 2018. The Wisconsin Controlled Substances Board added mitragynine and 7-hydroxymitragynine—the primary alkaloids in kratom—to the state’s Schedule I list, aligning with federal drug scheduling trends. Local law enforcement agencies, including the Wisconsin Department of Justice, actively enforce these prohibitions, with penalties ranging from misdemeanors to felonies depending on quantity and intent.
Key Regulations for Kratom in Wisconsin
- Schedule I Status: Mitragynine and 7-hydroxymitragynine are explicitly listed under Wisconsin Statute § 961.14(4)(t), prohibiting all forms of kratom, including leaves and extracts.
- Penalties: Possession of any amount constitutes a Class I felony, punishable by up to 3.5 years imprisonment and $10,000 fines; distribution or intent to sell escalates to Class H felonies with stricter penalties.
- Local Enforcement: Municipalities like Milwaukee and Madison have reinforced state bans through local ordinances, with police departments prioritizing kratom-related arrests in drug interdiction operations.
Wisconsin’s stance contrasts with neighboring states like Minnesota, where kratom remains unregulated but legal, creating compliance complexities for regional businesses. The Wisconsin Legislative Reference Bureau has not signaled reconsideration of the ban, and no 2026 legislative sessions propose amendments. Consumers or vendors risk severe legal consequences by circumventing these restrictions.
