LAW BREAKDOWN

LAW BREAKDOWNS

Marijuana use and possession is legal for adults 21 years and older, and those with a state-issued medical marijuana ID. Concentrates come with harsher penalties than other types of cannabis, and paraphernalia is also banned. Penalties for low-level offenders are relatively light, but other crimes may carry severe penalties.

Possession

As of 2021, adults can legally possess up to an ounce of marijuana and 8 grams of concentrates. Possession of marijuana is a misdemeanor in Montana as long as the amount is less than 60 grams (a little more than two ounces). For a first-time offender, the maximum penalty is six months in jail and a fine of $500. On a subsequent conviction, the top sentence increases to three years in prison and $1,000 in fines.

If the amount is greater than 60 grams, the offense is a felony and is punishable by as many as five years in prison and as much as $50,000 in fines. Possession of any amount with intent to distribute it carries a maximum sentence of 20 years in prison and $50,000 in fines.

Offense Penalty Incarceration Max. Fine
60g or less(first offense) Misdemeanor 6 months $ 500
60g or less(second offense) Misdemeanor 3 years $ 1,000
More than 60g Felony 5 years $ 50,000

Sale and Delivery

Sale or delivery of any amount of cannabis, with or without compensation, is a felony punishable by a minimum sentence of one year in jail and a maximum of life in prison, plus a top $50,000 fine. Sale or delivery of any amount from an adult to a minor carries an additional mandatory two-year sentence.

If the sale or delivery occurs within 1,000 feet of school grounds, the charge is a felony with a minimum sentence of three years in prison and a maximum of life, as well as up to $50,000 in fines.

Offense Penalty Incarceration Max. Fine
Any amount with or without compensation Felony 1 year* – life $ 50,000

Cultivation

Adults can legally cultivate up to four marijuana plants. If the grower cultivates less than one pound of cannabis or 30 plants, the charge carries a maximum sentence of 10 years in prison and $50,000 in fines on a first offense.

When the amount of cannabis cultivated is more than one pound or 30 plants, the prison term increases to between two years and life. Both the maximum prison term and the maximum fine double on second and subsequent convictions.

Offense Penalty Incarceration Max. Fine
1 lb or less or 30 plants or less Felony 10 years $ 50,000
More than 1 lb or more than 30 plants Felony 2 years – life $ 50,000
Second or subsequent offense is punishable by twice the term of imprisonment and twice the authorized fine.

Hash and Concentrates

Penalties for possession or manufacture of marijuana concentrates are harsher than those for bud. Adults may possess up to 8 grams of concentrate.

Possession of more than one gram is a felony and carries a top punishment of five years in prison and $1,000 in fines. Manufacture of hashish or other concentrates can be punished by up to 10 years in prison and $50,000. The sale of concentrates or possession with intent to sell them are both treated the same as regular marijuana sale or delivery.

Offense Penalty Incarceration Max. Fine
Possession of 1 gram or less (first offense) Misdemeanor 6 months $ 500
Possession of 1 gram or less (subsequent offense) Misdemeanor 3 years $ 1,000
Possession of more than 1 g Felony 5 years $ 1,000
Manufacture Felony 10 years $ 50,000
Penalties for the sale or possession with the intent to sell hashish are the same as for marijuana. Please see the marijuana penalties section for further details.
