Prohibited HIGH

Wisconsin

Wisconsin is fully prohibited — no medical or adult-use cannabis market exists.
Surrounded entirely by adult-use states (Michigan, Illinois, Minnesota), creating one of the most intense border market dynamics in the country.
Wisconsin residents spent an estimated $121.2 million on cannabis in bordering Illinois counties in 2022, generating $36.1 million in Illinois tax revenue.
Black Wisconsinites are 5.29 times more likely to be arrested for cannabis possession than white residents statewide; in some rural counties the disparity exceeds 30x.
Governor Evers has repeatedly championed legalization; the Republican-controlled legislature has blocked every attempt. No ballot initiative mechanism exists.
A Department of Revenue fiscal estimate projects a legal adult-use market would generate $258.15 million annually by FY 2029-30.

Wisconsin remains an island of prohibition in the American Midwest, maintaining strict laws against the possession, sale, and cultivation of cannabis for both medical and adult-use purposes. Surrounded entirely by states that have implemented robust, legal adult-use markets (Michigan, Illinois, and Minnesota), Wisconsin faces unique and unprecedented border dynamics. Millions of state residents live within a short drive of a legal dispensary, driving a massive outflow of capital and tax revenue to neighboring jurisdictions. Domestically, the state enforces some of the most punitive cannabis statutes in the region, resulting in thousands of arrests annually that disproportionately impact Black Wisconsinites. The political landscape surrounding cannabis in Wisconsin is defined by a deep, enduring partisan standoff. Democratic Governor Tony Evers has repeatedly championed the full legalization of cannabis, emphasizing the potential for economic growth, tax revenue generation, and criminal justice reform. However, the Republican-controlled State Legislature has consistently blocked these efforts. While some conservative lawmakers have recently attempted to introduce highly restrictive medical cannabis legislation, these efforts have routinely fractured over disagreements regarding the scope of the program and the mechanism of retail distribution. Consequently, Wisconsin operates under a localized patchwork of decriminalization ordinances in progressive urban centers, while state law enforcement continues to prosecute cannabis offenses severely across broader jurisdictions.

Criminal Justice

Group	Metric	Value
Black	Disparity Ratio vs. White residents	5.29x more likely to be arrested for cannabis possession statewide (2022) ^[19]
Black	Disparity Ratio vs. White residents (historical)	4.2x more likely statewide in 2018 — disparity has worsened ^[20]
Black	Disparity Ratio — Ozaukee County	34.9x more likely to be arrested for cannabis possession (2019)
Black	Disparity Ratio — Manitowoc County	29.9x more likely to be arrested for cannabis possession (2019)
Black — Milwaukee County	Conviction trend	Milwaukee County (which holds 69% of state's Black population) dropped cannabis convictions 94% — from 1,285 in 2010 to 96 in 2019. But 92% of Black cannabis possession convictions in Wisconsin now occur outside Milwaukee County.

While neighboring jurisdictions have evolved their posture toward cannabis, Wisconsin state law enforcement and local departments continue to dedicate significant resources to interdicting and prosecuting cannabis offenders. In 2023, total drug arrests rose 5% to 26,392 — with cannabis accounting for 55.6% of all drug arrests. In 2022, over 13,400 arrests were for cannabis offenses, the overwhelming majority for simple possession. Arrests have rarely dropped below 14,000 annually over the last decade, and between 2010 and 2018 cannabis possession arrests actually increased 12.1% as national trends moved the opposite direction. Wisconsin's racial enforcement disparities are among the worst in the nation. Despite comparable usage rates, Black Wisconsinites are 5.29 times more likely to be arrested for cannabis possession than white residents statewide — a worsening from the 4.2x ratio recorded in 2018. In rural and suburban counties the disparity reaches extremes: 34.9x in Ozaukee County and 29.9x in Manitowoc County. Milwaukee County has dramatically reduced its own cannabis convictions (down 94% from 2010 to 2019), yet 92% of Black cannabis possession convictions in Wisconsin now occur outside Milwaukee County — in areas holding only 31% of the state's Black population. No expungement pathway exists under current law.

What Wisconsin Is Leaving on the Table

If Wisconsin had adult-use cannabis sales at the level of operational states:

Benchmark	Per Capita	Rank	Estimated WI Market
Connecticut (#20)	$60.73	Lowest	$362M
New Jersey (#15)	$126.23	Mid-pack	$752M
Colorado (#9)	$196.26	Mature	$1.2B

Borders

Border Dynamics

Neighbor	Legal Status	Notes
Michigan	Adult-use operational (legalized 2018)	Dispensary operators in Michigan's Upper Peninsula publicly report a 'good majority' of patrons travel from Wisconsin. Marinette County Sheriff's Office reports traffic stops routinely uncovering legally packaged Michigan cannabis in Wisconsin-bound vehicles.
Illinois	Adult-use operational (legalized 2019)	Wisconsin residents spent $121.2 million in bordering Illinois counties in 2022 — roughly 50.6% of all retail sales in those jurisdictions. Illinois collected $36.1 million in tax revenue from these purchases.
Minnesota	Adult-use operational (legalized 2023)	Minnesota does not rigorously track out-of-state purchaser residency. Anecdotal border dispensary data indicates significant Wisconsin capital flow.
Iowa	Medical only (limited program)	Iowa shares Wisconsin's southern border and is itself a largely prohibited state; minimal cross-border cannabis flow expected.

Wisconsin's geographic position creates one of the most intense border market dynamics in the country. Entirely flanked by states with operational adult-use markets — Michigan (2018), Illinois (2019), and Minnesota (2023) — more than half of Wisconsin adults live within 75 minutes of a legal dispensary. Wisconsin residents spent an estimated $121.2 million in bordering Illinois counties alone in 2022, representing roughly 50.6% of all retail cannabis sales in those jurisdictions and generating $36.1 million in Illinois tax revenue. Michigan and Minnesota border activity is not formally tracked but is corroborated by dispensary operators and law enforcement. The Marinette County Sheriff's Office reports that traffic stops routinely uncover legally packaged Michigan cannabis in Wisconsin-bound vehicles — a product that is legal where purchased and illegal the moment it crosses state lines. State crime lab cannabis submissions spiked 15.5% from 2020 to 2021, tracking directly with the acceleration of neighboring legal markets.

Economic

Economic Opportunity

Fiscal Note: Wisconsin Department of Revenue Fiscal Estimate for SB 1045 (March 2026): 10% excise tax on producers/processors + 5% retail excise + 3% raw flower tax dedicated to Cannabis Research Fund + standard 5% state sales tax. Revenue projections: $23.72M (FY 2026-27) → $118.38M (FY 2027-28) → $192.41M (FY 2028-29) → $258.15M (FY 2029-30). Municipalities could levy an optional additional 5% local tax for an estimated $50M+ collectively. State administrative cost: 19 FTE positions at $2.66M annually.^[32]
Neighbor Revenue: Wisconsin residents spent an estimated $121.2 million on cannabis in bordering Illinois counties in 2022 (50.6% of all retail sales in those jurisdictions), generating $36.1 million in Illinois tax revenue. This figure derives from a 2023 Wisconsin Legislative Fiscal Bureau analysis of Illinois DFPR data. Michigan and Minnesota do not track out-of-state purchaser residency rigorously; anecdotal dispensary data near the Michigan border indicates substantial Wisconsin spending.

By maintaining prohibition, Wisconsin is actively exporting tens of millions of dollars in tax revenue to neighboring states while absorbing the fiscal and social costs of criminal enforcement. Wisconsin residents spent an estimated $121.2 million on cannabis in bordering Illinois counties alone in 2022, funding $36.1 million in Illinois tax revenue. Border purchases from Michigan and Minnesota are not formally tracked but are corroborated by law enforcement and dispensary operators. The Wisconsin Department of Revenue's March 2026 fiscal estimate for SB 1045 projects that a legal market would generate $23.72 million in its first year and scale to $258.15 million annually by FY 2029-30, modeled on Michigan and Illinois sales trends. An optional 5% local tax could add $50+ million more. No comprehensive study of private sector job creation has been published. The state's sole formal economic analysis is the DOR fiscal note, which identifies only the 19 FTE government positions required to administer the program.

Political

Political Trajectory

Active Bills: Senate Bill 1045 (2025-2026 session) — sponsored by nearly 50 Democrats. Would establish regulated adult-use and medical cannabis markets, allow home cultivation of up to 6 plants, create a Division of Cannabis Regulation within DATCP, and include automatic expungements. Projects $258.15M in annual revenue by FY 2029-30. Has not received a floor vote.
Polling Support: 63% of registered Wisconsin voters support adult-use legalization (January 2024). 86% support medical cannabis — including 95% of Democrats, 84% of Independents, and 78% of Republicans.
Ballot Initiative: Wisconsin does not allow citizens to initiate binding state-level ballot measures or constitutional amendments that bypass the legislature. Voters have approved non-binding advisory referendums in over a dozen counties during the 2018 and 2022 election cycles.^[19]

Wisconsin represents one of the most entrenched political standoffs on cannabis reform in the nation. The divide is strictly partisan: Governor Evers has championed full legalization in every biennial budget; Assembly Speaker Vos has killed every bill that reaches his desk. The Republican caucus itself is fractured — Senate leaders Felzkowski and Testin advanced a medical bill in February 2026, only for Vos to dismiss it immediately. Democratic proposals (most recently SB 1045) represent the policy Max cares about but have no path to passage under current leadership. Public opinion is massively out of step with legislative action: 63% of voters support adult use; 86% support medical. Wisconsin has no citizen initiative mechanism, so public will cannot bypass the legislature. The realistic trajectory is stagnation unless redistricting or a leadership change shifts the Assembly. Advisory referendums in more than a dozen counties reflect broad public appetite but carry no legal weight.
