Traveling to Montana, or do you live there and still don’t get the laws? We feel your pain, so we searched the web for you and pulled together the cannabis laws for consumers in Montana. 

Please note that laws are consistently changing and although we work hard to keep this information as up to date as possible we suggest checking with the state’s government site as well.

The Basics

The Need to Know


Patients must always carry their medical cards on them if they are carrying cannabis. As a patient you can possess up to one ounce of usable cannabis at a time.  

If you are caught with cannabis and are not a medical card holder you can face large fines and jail time.

Purchasing Limits

Medical card holders can purchase no more than one ounce of usable cannabis at a time.


You can legally consume cannabis on private property out of view from the public.

It is not allowed to consume cannabis on any federal or public land or in a parked or moving vehicle. If you are caught consuming in public you could face heavy fines. 


A medical patient who has not listed a provider may grow up to 4 mature plants and 4 seedlings. 

Driving Under the Influence

If you are found guilty of driving under the influence of usable cannabis you will face DUI charges and penalties, even if you are a medical patient.

If you lose your driver’s license (DL) because of a DUI you may also be required to surrender your medical cannabis card for the duration of your DL suspension. 

Transporting Marijuana

If you are a medical card holder, it is legal to transport cannabis as long as it is not accessed by anyone in the vehicle. 

Exporting Marijuana

Moving cannabis across state lines is illegal and can result in a steep penalty if you’re caught. 

It is also illegal to ship or send it in the mail.

Traveling by Plane

Cannabis is still illegal on the federal level so it is always a risk if you decide to fly with it. 


You can use your medical card in another state if that state has medical marijuana reciprocity.

Montana doesn’t offer reciprocity.
