Growing Marijuana In Missouri

Up until 2018, Missouri wasn’t known for having very friendly marijuana laws. Now Missouri has decriminalized marijuana, (unless you are carrying around kilos) and approved a medical marijuana program.

This doesn’t mean enjoying marijuana is easy in Missouri – growing and consuming it is still limited to a doctor’s approval, but the new legislation is definitely a step in the right direction.

Missouri’s Marijuana Possession Laws

It used to be that Missouri marijuana growing was treated the same as possession.

This meant that it was considered a misdemeanor to possess up to 35 grams. Now, however, the laws have changed to specifically recognize cultivate differently.

While that might sound like a good thing, it actually means that growing up to 35 grams of marijuana is a felony.

The laws regarding possession, meanwhile, have also changed a bit in recent years. If you are found possessing 10 grams or less of marijuana, it is a misdemeanor with no jail time and a $500 fine.

If you are found with the same amount for a second time, however, you could land in jail for a year, plus get a $2000 fine.

The penalty becomes a felony when a person is in possession of more than 35 grams of marijuana, which could end up with 7 years in prison and a $10,000 fine.

Oftentimes this much marijuana is considered “intent to distribute,” and that could lead to even more time in jail.

Distribution is clearly Missouri’s main concern, with a potential life sentence for people growing and/or distributing large amounts (100 kg or more), or distributing near a school, park, or public housing.

Medical Marijuana

Missouri residents voted to approve Amendment 2 in the November 2018 midterms which will begin a medical program by summer 2019.

The new law will legalize the use of up to four ounces of marijuana for qualified patients. Additionally, they can have up to a 60-day supply in their residence.

Patients will be able to purchase marijuana from state-licensed dispensaries. In the meanwhile, Missouri allows the use of Medical CBD for those with intractable epilepsy.

The medical CBD program defines the use of twenty ounces of high CBD cannabis extracts with no more than .03 of one percent of THC as legal for patients.
