TL;DR
Cannabis is illegal in Wisconsin. A first possession offense is a misdemeanor with up to 6 months in jail and a $1,000 fine; a second offense can be a felony. There's no medical program, apart from a narrow CBD oil law. Madison, Milwaukee and other cities have small local fines, but state law still applies.
Wisconsin is an island: Illinois, Michigan and Minnesota all have legal recreational cannabis. But Wisconsin has no legal cannabis program. Republican lawmakers have proposed a limited medical program, and Democrats have proposed full legalization, but neither has passed.
Is weed legal in Wisconsin?
No. Possessing, growing or selling cannabis is a crime, and Wisconsin doesn't recognize medical cards from other states.
Penalties
- First offense, any amount for personal use: a misdemeanor, with up to 6 months in jail and a $1,000 fine
- Second or later offense: a felony, with up to 3.5 years in prison
- Selling or growing: felony charges, based on amount
Madison, Milwaukee and many other cities have reduced local penalties for small amounts to a small fine, but county and state law enforcement can still charge you under state law.
CBD and hemp in Wisconsin
CBD products are legal, and a narrow law lets people with certain conditions possess CBD oil with a doctor's certification. Hemp products with no more than 0.3% delta-9 THC have been sold widely, but the federal hemp changes coming in late 2026 (below) will take many intoxicating hemp products off the shelves.
Crossing the border
Buying legally in Illinois, Michigan or Minnesota doesn't protect you in Wisconsin. Bringing cannabis back across the state line is illegal.
Driving and work
Driving with any detectable THC in your blood can lead to an OWI charge. Employers can test for and ban cannabis use.
Is anything changing in 2026?
No. Medical cannabis and legalization bills were introduced in the 2025-26 session, but neither passed before the legislature wrapped up in spring 2026. Wisconsin doesn't have a citizen ballot initiative process.
Federal law in 2026
Federal law still treats recreational cannabis as illegal. In April 2026, the federal government moved marijuana sold under a state medical license (and FDA-approved cannabis medicines) to Schedule III, but adult-use cannabis is still Schedule I. That means it's still banned on federal land and can't legally cross state lines, even between two legal states.
Separately, a federal ban on intoxicating hemp products takes effect in two steps: synthetic and converted cannabinoids like delta-8 lose their legal status on November 12, 2026, and naturally derived hemp THC (THCA flower, hemp delta-9 edibles and drinks) on December 11, 2026.
