Marijuana Laws in Wisconsin

In the State of Wisconsin, cannabis is a Schedule I hallucinogenic drug. Possessing even the smallest amount of marijuana for personal use will get you a hefty fine and possible jail time.

Wisconsin Governor Scott Walker signed Senate Bill 10 into legislation in 2016. This expanded Lydia’s Law, the medical cannabis law put in place in 2014. This allows physicians to recommend cannabidiol (CBD) products to patients with any debilitating, chronic medical condition. In other words, qualifying patients could possess medicinal CBD products. However, it was still illegal to produce these products within the state.

Then, on April 17, 2017, Walker signed Act 4. This allows qualifying patients to possess CBD products without fear of state prosecution. So, if they somehow obtain the products out-of-state, it would be lawful, state-wise, to possess them in Wisconsin. To date, it is still illegal to produce or distribute these products in this state.

Representative Jimmy Anderson and Senator Chris Larson introduced S104 and A158 to legislatures. It proposes allowing local businesses to become state-licensed to produce and dispense CBD-infused products for medicinal treatments. Representative Melissa Sargent announced in July that she plans to introduce a bill that regulates, taxes and legalizes marijuana in Wisconsin for adult use.

Concentrates & Hashish

According to Wisconsin state law, any compound that contains THC is considered to be a Schedule I drug. This definition does not include concentrate or hashish. However, the offenses and penalties for those offenses are the same as those for possessing plant for cannabis. See “Possessing Marijuana in Wisconsin” for penalty details.


Because it is illegal to possess or use marijuana, it is also unlawful to use or possess cannabis paraphernalia in Wisconsin. The state’s definition of paraphernalia is any item or device that allows you to distribute, cultivate, inhale or ingest marijuana. This is a misdemeanor offense with up to a $500 fine and no more than 30 days’ incarceration.

Medical Marijuana

SB 10, which was signed in 2016, allows Wisconsin qualifying patients with physician recommendations to possess CBD products in the state. These products must be in forms that do not provide psychoactive effects. In other words, they must contain CBD, but cannot contain tetrahydrocannabinol (THC).

Currently, there are no medical marijuana dispensaries in Wisconsin. The State has yet to provide these patients with legal means of obtaining the CBD-infused products.

Selling Marijuana in Wisconsin

It is a felony crime to cultivate or sell any amount of cannabis in Wisconsin. Related crimes are punishable as follows:

  • Between 200 to 1,000 grams (5 to 12 plants) = Fines up to $10,000 and/or no more than 6 years’ incarceration
  • Between 1,000 to 2,500 grams (21 to 50 plants) = Fines up to $25,000 and/or no more than 10 years’ incarceration
  • Between 2,500 to 10,000 grams (51 to 200 plants) = Fines up to $25,000 and/or no more than 12 ½ years’ incarceration
  • Over 10,000 grams (over 200 plants) = Fines up to $25,000 and/or no more than 15 years’ incarceration


Selling Marijuana

No one may sell drug paraphernalia in Wisconsin. Such crimes are misdemeanors, and punishable as follows:

  • Selling = Up to $1,000 fine and/or incarceration for 90 days
  • Selling to minor = Up to $10,000 fine and/or incarceration for no more than 9 months

Growing and Manufacturing Marijuana in Wisconsin

Wisconsin lawmakers punish crimes related to manufacturing, cultivating and growing cannabis the same as those related to selling the drug. Related penalties are based on the amount of plants possessed. See “Selling Marijuana in Wisconsin” for penalty details (plant amounts).

Medical Marijuana

Current Wisconsin law allows qualifying patients to possess CBD products for medicinal purposes. However, state lawmakers have yet to make it legal for any entity to produce these products.

Two state legislators have introduced bills that would change this Catch 22 situation. S 104 and A 158 would allow approved businesses in Wisconsin to become licensed to produce CBD products and dispense them to qualifying medical cannabis patients.

Using Marijuana in Wisconsin

Wisconsin lawmakers have yet to allow the use of the plant form of cannabis for recreational or medicinal purposes. It is unlawful to inhale, ingest, consume or use the plant form of marijuana in this state.

Medical Marijuana

However, Wisconsin state law does allow patients with qualifying medical conditions to possess and use CBD-only products for medical treatment purposes. These products contain CBD, but cannot contain any THC.

Currently, there are operational dispensaries in Wisconsin. Therefore, there are no legal ways for these patients to obtain the CBD products within the state.
