Growing Marijuana in Minnesota – State Laws (2020)

Even though Minnesota already has a medical cannabis program and a very restrictive one at that, it seems like marijuana supporters will have to push reform up a steeper slope in the next few years.

The North Star State is considered to be Democratic but despite this, Republican lawmakers have largely been successful in shooting down pro-marijuana legislation. In fact, the most recent legalization bill, HF 4632, failed to advance before the legislature adjourned last May due to strong opposition from the Republican caucus. The bill, which was called the “best legalization bill in the country” by its sponsor House Majority Leader Ryan Winkler, would have allowed possession, gifting of small amounts, and even home cultivation of up to eight marijuana plants. 

It is quite evident that the only obstacle standing between Minnesotans and marijuana legalization is Republican disruption. According to a recent poll, around 51% of residents are already in favor of recreational pot while only 37% are opposed. This could be a problem since some experts believe that Minnesota might slowly be turning red. It has also been reported that some Republican candidates are actually running in support of legalization perhaps to confuse voters and draw votes away from the Democratic Farmer Labor Party.    

Now that legalization efforts have ended for this year, lawmakers are expected to take HF 4632 as a basis for legislation that can be considered when the session resumes in 2021.

Overview of Minnesota Marijuana Laws

Medical marijuana is legal in Minnesota but recreational use, as well as home cultivation of any kind, is still illegal. 

  • Possession – Possession of 42 and ½ grams or less is a misdemeanor in Minnesota but it only gets a maximum fine of $200 without jail time since a conditional discharge is usually given to first-time offenders. Any amount exceeding is charged as a felony. Having more than 1.4 grams in one’s vehicle is also a misdemeanor but gets 90 days jail time and a fine of up to $1000. 
    • 42.5 g to less than 10 kg – up to 5 years imprisonment and a maximum fine of $10,000
    • 10 kg to less than 50 kg – up to 20 years imprisonment and a maximum fine of $250,000
    • 50 kg to less than 100 kg – up to 25 years imprisonment and a maximum fine of $500,000
    • 100 kg or more – up to 20 years imprisonment and a maximum fine of $250,000
  • Sale – The offense of selling marijuana in Minnesota is a felony that gets the same penalties as possession. However, selling any amount to a minor is automatically a felony that gets up to 30 years imprisonment and a maximum fine of $1,000,000. Likewise, distributing in a school zone or similar areas is a felony punishable by up to 15 years imprisonment and a maximum fine of $100,000 
  • Cultivation – The penalties for marijuana cultivation in Minnesota is based on the aggregate weight of the plants involved. The corresponding penalties are the same as in possession/sale.

History of Marijuana in Minnesota

Although the Land of 10,000 Lakes decriminalized marijuana in the early 70s, barely anything happened decades afterward in terms of marijuana reform. In fact, it barely made a dent on the number of marijuana-related arrests which peaked in 2012. Worse yet, the law was enforced unequally, with black people 5.37 times more likely to be arrested for pot than white people. 

Medical Marijuana Act

In 2014, then Gov. Mark Dayton signed the state’s Medical Marijuana Act which is known to be one of the most restrictive cannabis programs in the country. Even though Dayton was a Democrat, he was not exactly supportive of marijuana and even said that legalization of recreational cannabis won’t be happening on his watch. His signing of the medical marijuana bill was heavily criticized by marijuana supporters who pointed out that the law excludes a lot of critically ill Minnesotans. Dayton defended his stance, saying that the law had to strike a compromise between what marijuana proponents and law enforcement want. 

Initially, the program only allowed patients with cancer (with pain, nausea, vomiting, and/or wasting), glaucoma, HIV/AIDS, tourettes, ALS (Lou Gehrig’s Disease), seizure, multiple sclerosis, Crohn’s disease, or a debilitating terminal illness with less than a year to live. Qualifying patients may only take the medical marijuana in liquid, pill or vaporized form but not as dried plant material. However, the list of conditions was expanded in 2016 to add “intractable pain” and PTSD in 2017. Chronic pain and age-related macular degeneration were also added in 2019 and became effective just last August 2020.

Failed 2020 legalization effort

Dayton was succeeded by fellow DFL member Tim Walz in 2018. Walz showed his support for cannabis, arguing that a regulated market could be a new source of tax revenue and may even reduce the number of people locked up for drug offenses. The following year, Senator Melisa Franzen and Representative Mike Feiberg and Senator Scott Jensen introduced a recreational marijuana bill that would allow people over 21 to possess, grow, and purchase in limited quantities. This bill got shut down by Republican opposition in 2019, with the sponsors saying that Republicans and even Governor Walz chose not to convene a task force to study the matter further.

It is clear that in the case of Minnesota, the only hurdle for legalization to happen are the Republicans in the Senate. Marijuana campaigners need to increase their effort in making voters aware who are the candidates pushing for marijuana legislation that would create a regulated marijuana industry that provides jobs, brings in tax revenue, and reduce unnecessary stops, searches, and arrests especially against black residents.
