Idaho Marijuana Laws
Idaho marijuana laws ban marijuana for both medical and recreational use: Idaho issues no medical marijuana card and does not recognize cards from other states. This guide covers possession, purchase, home growing, out-of-state cards and public use.
Is Marijuana Legal in Idaho?
Idaho bans marijuana for both medical and recreational use, and Idaho Code 37-2705 lists it in schedule I. Even a small amount is a crime: since July 1, 2025, an adult caught with 3 ounces or less faces a fine of at least $300. No Idaho law lets a patient use marijuana for symptoms, and Idaho treats a THC edible as marijuana unless it qualifies as licensed hemp.
Is Medical Marijuana Legal?
No, medical marijuana is not legal in Idaho, and no Idaho law has changed that; in 2025 lawmakers instead sent voters HJR 4. However, citizens have tried the ballot: medical marijuana initiatives were circulated for 2022, 2024 and 2026, and none qualified. An earlier medical marijuana initiative, circulated for 2020, did not qualify for the ballot either, and no Idaho law has created a medical program. Years earlier, a 2015 bill that would have allowed limited use of cannabidiol oil, S 1146, passed the Legislature but was vetoed by the Governor. The latest initiative, the Idaho Medical Cannabis Act, did not collect enough valid signatures, in total or by legislative district, to reach the Nov 3, 2026 ballot.
Is Recreational Marijuana Legal?
No. Recreational marijuana is illegal in Idaho in every form, including edibles, vapes and concentrates that are not licensed hemp. There are no exceptions to this and those who are found in possession or caught using marijuana recreationally can be punished with fines and jail time.
When Will Medical Cannabis Be Available in Idaho?
No date is set. Medical cannabis is not legal in Idaho, and the 2026 Idaho Medical Cannabis Act initiative failed to qualify for the ballot. On Nov 3, 2026, voters decide HJR 4, which would amend Article III, section 26 of the Idaho Constitution so that only the Idaho Legislature could legalize marijuana. A yes vote would also end citizen initiatives that legalize it, so any future medical program would have to pass as a bill.
Idaho Marijuana Laws Under Title 37
The specifics of Idaho marijuana laws below come from Idaho Code Title 37, chapter 27, the Uniform Controlled Substances Act, which covers possession, sale, trafficking and public use.
Possession & Purchase
It is illegal to buy, sell, or possess any amount of marijuana in Idaho, because Idaho Code 37-2705 lists it in Idaho’s schedule I. Those found with 3 oz or less face a misdemeanor under Idaho Code 37-2732, with up to one year in jail, a fine up to $1,000, or both, plus a $300 minimum fine for adults; more than 3 oz is a felony with up to 5 years in prison, and 1 pound or more is trafficking.
How Much Can I Buy and Possess?
You are not allowed to buy or possess any quantity of marijuana in the state of Idaho. Even very small amounts are punishable by law and can result in both fines and jail time.
Where Can I Obtain Cannabis?
It is not possible to obtain marijuana legally in Idaho. There are no laws allowing for medical or recreational usage of marijuana, and the state does not license or allow any cannabis dispensaries to operate within its borders.
Who Can Legally Purchase Cannabis in Idaho?
Nobody is legally allowed to purchase marijuana in Idaho. Among the cannabis-related products Idaho law excludes from its definition of marijuana are the drug Epidiolex, which contains cannabidiol, and licensed hemp with no more than 0.3% total delta-9 THC. Even so, Idaho’s Office of Drug Policy says any CBD product found in an Idaho store or marketplace must contain zero THC.
Home Cultivation
Home cultivation is illegal in Idaho.
Reciprocity
Idaho does not recognize medical marijuana cards from other states.
Consumption
Idaho forbids any use of marijuana, either recreational or medical.
Where Can I Safely Consume Cannabis?
It is illegal to consume marijuana in Idaho. There are no safe or legal spaces to use any product that counts as marijuana, and public use is a separate misdemeanor.
Qualifying Patients
In states with a medical program, patients with a qualifying condition can get legal access to marijuana products. However, there are no provisions for medical cannabis in Idaho, so it’s not accessible to anyone, regardless of their health condition or any diseases that they might be suffering from. The 2026 Idaho Medical Cannabis Act initiative listed conditions such as cancer, HIV, glaucoma, Alzheimer’s and Crohn’s disease, but it failed to qualify for the ballot, so none of them is a qualifying condition in Idaho.
Are Edibles Legal in Idaho?
No, edibles are not legal in Idaho: an edible containing THC that is not licensed hemp is a preparation of marijuana under Idaho law, and possessing one is penalized the same way.
How to Obtain a Medical Card?
Idaho does not currently have any kind of marijuana card program, so you cannot obtain an Idaho medical marijuana card. If you wish to use medical marijuana, the only option is to wait for future legislation or move to another state.
Idaho’s marijuana law is strict: it is illegal to have or use any amount of marijuana, whatever your intent or health. A change to Idaho marijuana laws would take a new statute or a constitutional amendment, and the Idaho Secretary of State lists every measure on the ballot at voteidaho.gov.
