Marijuana Possession Laws in Minnesota

Possession of marijuana in Minnesota is sometimes a crime

Marijuana possession laws in Minnesota:  One hundred years ago, things were simple. Marijuana was always legal, all the time.

Then in the 1930s came Prohibition.

In recent decades the failed experiment in marijuana criminalization is crumbling at last.  But we’re not there yet.  Today in Minnesota, some forms of marijuana are legal to possess.  Others are not yet.

When is marijuana legal in Minnesota?

Legal marijuana:  Lawful participants in Minnesota’s Medical Marijuana Program, under the administration of the Minnesota Department of Health, can legally possess marijuana provided to them in compliance with Minnesota law, from one of the two authorized providers of Minnesota Medical Marijuana.

Medically prescribed Epidiolex is marijuana CBD.  It’s legal too in Minnesota, available at your local pharmacy.

Hemp is legal cannabis:  Hemp is “the plant Cannabis sativa L. and any part of the plant, whether growing or not, with a delta-9 tetrahydrocannabinol (THC) concentration of not more than 0.3 percent on a dry weight basis.”

Hemp is not “marijuana.”  Marijuana is cannabis with more than 0.3 percent THC on a dry weight basis.  Both are varieties of the cannabis plant.  Hemp is another legal form of cannabis.

Decriminalized marijuana:  Persons in Minnesota can possess “a small amount of marijuana,” defined as 42.5 grams or less of marijuana other than “the resinous form of marijuana,” without committing a “crime.” It is, however, a petty misdemeanor violation subject to a fine.

But possession of other kinds or amounts of marijuana is still a crime in Minnesota.

Marijuana possession crimes in Minnesota



Minnesota law ranks the severity levels of marijuana possession crimes mainly by weight.  The Minnesota weight thresholds are:

  • 50 kilos plus
  • 25 kilos plus
  • 10 kilos plus
  • Any measurable amount, except “a small amount” of marijuana
  • 42.5 grams or less but more than 1.4 grams of “marijuana” in a motor vehicle. Does not include “the resinous form of marijuana.”
  • 42.5 grams or less “marijuana:” petty misdemeanor.  Does not include “the resinous form of marijuana”
Plants – possession based on number:
  • 500 or more “marijuana plants”
  • 100 or more “marijuana plants”
Mixture – Bong Water Exception

1st, 2nd, 3rd degree: In measuring the weight of a “mixture,” prosecutors may not use the weight of fluid in a water pipe unless four or more fluid ounces.  The fact that Minnesotans have been sent to prison for bong water shows how ridiculous the mixture law is.

Possession as a legal fiction – actual vs. “constructive possession”

First, in order to make possession of a thing a crime, there must be evidence proving criminal intent.

The lowest level of criminal intent applicable to a possession of contraband case is “knowledge.”  In other words, it’s not enough that some prohibited item is found near or on your person.  The prosecutor must prove that the person accused actually knew it was there.

Where possession is the crime, frequently the central issue is whether the accused actually knew where the forbidden item was.  If they did not know, they cannot be guilty of a crime of “knowing possession.”

In fact, one of the first questions police officers ask suspects in a possession case invite an admission of knowledge“Is this your marijuana?”

Circumstantial evidence of knowing?

Dad, can I borrow the car?

“Dad, can I borrow the car?”

The government will often attempt to prove knowing possession with circumstantial evidence (“constructive possession”).  This is indirect evidence that they assert supports an inference of knowledge.

But frequently circumstances also support an inference of a lack of knowledge.

Where an inference of innocence is possible from circumstantial evidence, the law requires the jury to conclude the accused is not-guilty.

A common misconception is that ownership is the same as possession.  It is not.

Let’s consider an example.  If a child borrows and drives the parent’s car, the child is in possession of the car.  But the owner is still the parent, who is not in possession of it.

Identification of the marijuana or THC

The government has the burden of proving in court whether the material claimed by them to be marijuana or THC, actually is.   The statutes make a “mixture containing” marijuana or THC, a crime to knowingly possess.

But the definition of marijuana excludes parts of the cannabis plant form the definition of marijuana.  These laws directly conflict with each other.

Since the marijuana definition statute is more specific, under principles of statutory construction the more specific statute should be enforced over the more general “mixture” statutes.

Minnesota’s Importing Marijuana Across State Borders crime 

Minnesota has a marijuana crime for “importing across state borders.”  Prosecutors rarely charge it.  When they do, the penalty is heavy.  This is no surprise since it incorporates the lesser-included offense of Controlled Substance Crime First Degree — Possession, Minnesota Statutes 152.021, subd. 2.  The cases we’ve had where this crime was charged had serious problems of proof for the state.

Marijuana Possession Defense

Sometimes we assert affirmative defenses, as well, though this is not required and depends upon the specifics of each case.
