Marijuana is not legal in Milwaukee. Wisconsin classifies THC as a Schedule I controlled substance, so possession, sale, and use are crimes under state law. What makes Milwaukee different from the rest of the state is a city ordinance that lets Milwaukee police handle small-amount possession as a municipal violation with a fine as low as $0 instead of a criminal charge. That local policy is narrow, and it disappears the second you leave city limits, get stopped by anyone other than MPD, drive with THC in your system, or pick up a second offense.
What the Milwaukee Ordinance Actually Does
Milwaukee Code of Ordinances section 106-38 allows city police to cite someone caught with 25 grams or less of marijuana for a municipal forfeiture of $0 to $50 plus court costs, instead of referring the case for state prosecution.1City of Milwaukee. Milwaukee Code of Ordinances Chapter 106 – Morals and Welfare The Common Council set the floor at zero on purpose, giving judges room to impose essentially no monetary penalty. Community service and substance abuse counseling are also available as alternatives.
Two important limits sit inside the same ordinance. Smoking marijuana in a public place is treated separately and carries a forfeiture of $250 to $500.1City of Milwaukee. Milwaukee Code of Ordinances Chapter 106 – Morals and Welfare Possession at home and smoking on a sidewalk or in a park are not the same thing under this law. And if the amount is over 25 grams, or the person has a prior Wisconsin marijuana conviction, the ordinance steps aside and a criminal complaint can be filed under state law instead.
Paraphernalia is also its own ordinance. Section 106-36 covers pipes, water pipes, bongs, and similar items, with a forfeiture up to $500 and up to 30 days in jail if the fine goes unpaid.1City of Milwaukee. Milwaukee Code of Ordinances Chapter 106 – Morals and Welfare The pipe can cost ten times what the city will fine you for what’s inside it.
Wisconsin State Penalties Still Apply
Outside the narrow municipal track, Wisconsin treats THC as a Schedule I hallucinogen alongside heroin and LSD.2Wisconsin State Legislature. Wisconsin Statutes Chapter 961 – Uniform Controlled Substances Act A first-offense possession charge is a misdemeanor punishable by up to six months in jail and a fine up to $1,000. There is no minimum quantity; any amount qualifies.3Wisconsin State Legislature. Wisconsin Code 961.41(3g)(e) – Possession of THC
A second or subsequent offense is a Class I felony: up to three and a half years in state prison and a $10,000 fine. The definition of “subsequent” is broader than most people assume. Any prior drug-related misdemeanor or felony conviction under Wisconsin law, federal law, or the law of any other state counts.3Wisconsin State Legislature. Wisconsin Code 961.41(3g)(e) – Possession of THC A years-old misdemeanor from college in another state can turn a routine Milwaukee arrest into a felony.
Driving With Any THC in Your Blood
This is where Milwaukee residents get into the most serious trouble. Under Wis. Stat. § 346.63(1)(am), it is illegal to operate a motor vehicle with any detectable amount of a restricted controlled substance, including delta-9-THC, in your blood.4Wisconsin State Legislature. Wisconsin Code 346.63 – Operating Under Influence of Intoxicant or Other Drug It is a per se rule. Prosecutors do not have to prove impairment, only presence.
THC can stay in blood for days or weeks after use. Someone who smoked legally in Illinois over a weekend can test positive at a Milwaukee traffic stop the following week and face an OWI charge. The statute offers a narrow defense for a valid delta-9-THC prescription, but Wisconsin has no medical marijuana program, so that defense is realistically unavailable.4Wisconsin State Legislature. Wisconsin Code 346.63 – Operating Under Influence of Intoxicant or Other Drug A first OWI is a civil forfeiture; later offenses are criminal and carry mandatory jail time.
Where Milwaukee’s Ordinance Stops Protecting You
The $0–$50 forfeiture policy only applies when Milwaukee Police officers handle the stop within city limits. Several places inside or near Milwaukee look like the city but operate under different rules.
Milwaukee County Parks
County parks run under county ordinances enforced by county deputies and park rangers, not under the city ordinance. Fines for controlled substance violations in county parks can be considerably higher than the city’s $0 to $50 range, even when the park is surrounded by the city.
UW-Milwaukee and Other Campuses
The University of Wisconsin-Milwaukee prohibits all unlawful drug possession on campus, and campus police enforce state law rather than the city ordinance. Possession on campus can result in a criminal charge, disciplinary probation, suspension, or expulsion, and a drug-related conviction can affect federal student financial aid eligibility.5University of Wisconsin-Milwaukee. Drug-Free Student Annual AOD Notification
Federal Property
The federal courthouse, VA hospital grounds, the post office, and other federal sites in Milwaukee are governed by federal law. Under 21 U.S.C. § 844, simple possession of any controlled substance on federal property carries up to one year in jail and a minimum $1,000 fine for a first offense; a second offense carries 15 days to two years and a minimum $2,500 fine.6Office of the Law Revision Counsel. 21 USC 844 – Penalties for Simple Possession Federal convictions cannot be addressed through Wisconsin’s expungement process.
Bringing Marijuana In From Illinois, Michigan, or Minnesota
Milwaukee residents routinely drive to dispensaries across state lines. Any product purchased legally in another state becomes illegal the moment it crosses into Wisconsin.7PBS Wisconsin. When Wisconsinites Buy Legal Marijuana in Neighboring States There is no exception for licensed dispensary purchases, and Wisconsin does not recognize other states’ recreational or medical marijuana laws, including medical marijuana cards from Illinois, Michigan, or Minnesota. A second-offense charge under Wisconsin law is a felony regardless of where the product was bought.3Wisconsin State Legislature. Wisconsin Code 961.41(3g)(e) – Possession of THC
Medical Marijuana and CBD
Wisconsin has no medical marijuana program. No dispensaries, no patient registry, no legal access to high-THC flower or edibles for medical use. The only medical cannabis provision is a narrow CBD exemption under Wis. Stat. § 961.32(2m). A patient can possess cannabidiol with a certification from a licensed physician stating it is used to treat a medical condition; the certification lasts one year unless the physician sets an earlier date.8Wisconsin State Legislature. Wisconsin Code 961.32(2m)(b) – Cannabidiol Possession The CBD itself has to be in a form without psychoactive effect.9Wisconsin State Legislature. Act Memo 2017 Wisconsin Act 4 This is not a medical marijuana card and does not authorize THC products.
Hemp, CBD Retail, and Delta-8
The 2018 Farm Bill removed hemp from the federal Controlled Substances Act, defining it as cannabis with no more than 0.3 percent delta-9-THC by dry weight.10Food and Drug Administration. Hemp Production and the 2018 Farm Bill CBD oils, tinctures, edibles, and hemp flower that meet that threshold are legal to buy and possess in Milwaukee.
Delta-8 THC currently sits in a gray area. It can be derived from hemp, and Wisconsin’s statutes focus on delta-9-THC, so Delta-8 products are sold openly across the city. The 2025–2027 state budget proposal included language that would classify delta-8 and delta-10 THC as marijuana. Whether that provision becomes law is unresolved, and anyone relying on Delta-8 products should expect the rules to change.
Job, Housing, and Record Consequences
Wisconsin has no state law protecting employees from termination based on off-duty marijuana use. Private employers can test for THC and fire employees who test positive, including for use that occurred legally in another state. Milwaukee’s ordinance has no effect on workplace drug policies.
Housing is a similar story. Federally subsidized housing, including public housing authorities and Section 8, follows HUD rules tied to the Controlled Substances Act. Federal law requires public housing authorities to deny admission to current users of illegal drugs. For existing tenants, HUD guidance leaves eviction decisions to the housing authority’s discretion rather than mandating removal, but the authority is still there. Private landlords can write drug-free clauses into leases and enforce them regardless of the city’s fine policy.
A conviction can also be hard to clear. Wisconsin’s expungement law under Wis. Stat. § 973.015 requires the court to order expungement at the time of sentencing; if nobody asks then, the opportunity is gone. Eligibility is capped at offenses committed before age 25 with a maximum possible sentence of six years or less.11Wisconsin State Legislature. Wisconsin Code 973.015 – Special Disposition Even when granted, expungement only seals court records from public view; records held by the Department of Justice, the Department of Corrections, and law enforcement remain. A municipal forfeiture handled under the Milwaukee ordinance, by contrast, is not a criminal conviction in the first place, which is the main practical benefit of the local policy.
