Cannabis Laws in Wisconsin: What You Need to Know

Wisconsin holds a distinction that stands out more every year: it's the only state on Lake Michigan, and the only state in the Midwest, without any form of legal cannabis access. Home cultivation is illegal in Wisconsin under all circumstances — there is no medical or recreational framework of any kind.

Is Cannabis Legal in Wisconsin?

No. Wisconsin has no medical marijuana program and no recreational framework. The only exception is a narrow 2014 law known as Lydia's Law, which permits low-THC CBD oil for a limited set of medical conditions with physician certification — but Wisconsin doesn't follow the standard federal 0.3% THC threshold most other states use, applying an even stricter near-zero standard instead. There are no dispensaries, no patient registry, and no legal in-state way to obtain cannabis for any purpose. Possession of any amount is a criminal offense, though cities including Madison, Milwaukee, and Green Bay have local ordinances that reduce small possession to a civil citation.

Wisconsin's isolation has become more pronounced as its neighbors moved forward: Illinois legalized in 2020, Michigan in 2018, and Minnesota's adult-use retail sales began in September 2025. Wisconsin does not recognize out-of-state medical cards, and bringing cannabis across the border from a neighboring legal state is a violation of Wisconsin law the moment you cross.

Home Cultivation Remains Fully Illegal

With no medical or recreational program in place, there is no legal pathway in Wisconsin to grow cannabis at home for any reason.

Where Things Stand in 2026

Wisconsin's Democratic governor, Tony Evers, has included cannabis legalization in his budget proposal every cycle since 2019 — his 2025-2027 budget projected $58.1 million in state revenue from a 15% wholesale and 10% retail tax, and would have legalized possession up to 2 ounces and home cultivation of up to 6 plants. The Republican-controlled Joint Finance Committee stripped those provisions out on May 8, 2025, the same outcome as in 2023. Separately, a Republican-sponsored medical cannabis bill cleared a Senate committee in fall 2025 but never received a floor vote, and Senate Democrats filed a new adult-use bill, SB 1045, in February 2026 — GOP leadership has indicated it won't advance either. A federal rescheduling action in April 2026 moved some marijuana products to Schedule III, but since Wisconsin has no state-licensed medical program, that change doesn't reach any conduct within the state.
