Cannabis in Montana: lounges, dispensaries & laws
In Montana, recreational and medical cannabis are legal (legalized in 2020). Adult possession is capped at 1 ounce or less of usable marijuana for adults 21+, of which no more than 8 grams may be in concentrated form and no more than 800 mg of THC may be in edible marijuana products (MCA 16-12-106). Amounts above the personal limit that were home-grown must be kept in a locked space at one private residence and not visible from a public place by normal, unaided vision. Possession of 1-2 oz is a civil infraction ($200 first offense, $300 second); over 2 oz is a felony.
Can you legally consume on site in Montana?
Not permitted
No. Montana does not permit licensed cannabis consumption lounges, cannabis cafes, or hospitality venues, and none are operating. The Department of Revenue's Cannabis Control Division issues only six license types — cultivator, dispensary, manufacturer, testing lab, transporter, and combined-use (a tribal-only cultivation-plus-dispensary license) — and there is no hospitality, lounge, or on-site consumption category. Dispensaries are expressly not permitted to allow on-site consumption. The one statutory nuance: MCA 16-12-106 exempts smoking 'in an area licensed for that activity by the department' from the public-use fine, so the enabling language from I-190 contemplates such venues, but the department has never created the license type or written rules for it, so the exemption is currently a dead letter. SB 27 (2025) additionally froze new cannabis licenses and premises statewide through June 30, 2027, which forecloses any near-term rollout. Note: MPP's state-by-state on-site consumption table describes Montana in terms that actually match Colorado's hospitality law — that row appears to be a data error and should not be relied on. The 2027 legislative session is the earliest realistic point at which lounges could be authorized.

- Adult-use possession
- 1 ounce or less of usable marijuana for adults 21+, of which no more than 8 grams may be in concentrated form and no more than 800 mg of THC may be in edible marijuana products (MCA 16-12-106). Amounts above the personal limit that were home-grown must be kept in a locked space at one private residence and not visible from a public place by normal, unaided vision. Possession of 1-2 oz is a civil infraction ($200 first offense, $300 second); over 2 oz is a felony.
- Medical possession
- Registered cardholders may possess up to 1 ounce of usable marijuana on their person. Equivalency: 1 ounce of flower = 800 mg THC in edibles/infused products, or 8 grams / 8 mL of concentrate.
- Purchase limit
- Adult-use: 1 ounce of usable marijuana per day per person, with the same 8 g concentrate / 800 mg edible THC sublimits. Medical cardholders: up to 1 ounce of flower per day and no more than 5 ounces per month; cardholders may petition the Department of Revenue, with physician confirmation, to raise the monthly cap to 8 ounces.
- Home cultivation
- Adults 21+ may cultivate 2 mature plants and 2 seedlings per person. Registered medical cardholders may cultivate 4 mature plants and 4 seedlings. Per-residence cap is twice the individual allowance regardless of how many adults live there: 4 mature + 4 seedlings for an all-adult-use household, 8 mature + 8 seedlings for an all-cardholder household. Plants and any excess harvest must be kept in a locked space in or on the grounds of a single private residence and not visible from a public place by normal, unaided vision. Landlords may prohibit cultivation on their property.
- Public consumption
- Public consumption is prohibited. MCA 16-12-106 states that a person who smokes marijuana in a public place, other than in an area licensed for that activity by the department, is subject to a civil fine not exceeding $50. In practice there is no such licensed area — the Department of Revenue has never created a license type for on-site consumption. Consumption is also barred in vehicles, on federal land (Glacier and Yellowstone National Parks, national forests, BLM land), and inside dispensaries. Many hotels, motels, and short-term rentals ban smoking entirely.
- Minimum age (adult-use)
- 21
- Minimum age (medical)
- 18 for adult cardholders. Minors may qualify with a parent/legal guardian acting as caregiver, and minor applications require sign-off from two physicians unless the certifying physician is an oncologist, neurologist, or epileptologist.
- Out-of-state medical cards
- No. Montana does not honor out-of-state medical marijuana cards. Registration requires proof of Montana residency and a written certification from a Montana-licensed MD or DO, so non-residents cannot obtain or use a card here. Visiting patients 21+ should simply buy from an adult-use dispensary instead; visiting patients under 21 have no legal access.
- Qualifying conditions
- A defined statutory list rather than open physician discretion. Covered conditions include cancer, glaucoma, HIV/AIDS, epilepsy and seizure disorders, chronic or intractable pain, PTSD, Crohn's disease, multiple sclerosis, cachexia/wasting syndrome, severe nausea, painful peripheral neuropathy, central nervous system disorders producing spasticity, and admittance to hospice care. Moderately narrow compared with states that allow 'any condition a physician deems appropriate.' Verify the current list with the Department of Revenue.

Cities in Montana
Visiting Montana
Buy from an adult-use dispensary and consume in a private residence — that is effectively your only legal option, because Montana has no consumption lounges of any kind and no licensed venue where a visitor can legally smoke. The county map matters: adult-use retail exists only in 'green' counties that voted for I-190 in 2020 (Missoula, Gallatin/Bozeman, Yellowstone/Billings, Flathead, Lewis and Clark, Silver Bow and others), while 'red' counties are medical-only unless they opt in by local election, so plan purchases around your route rather than assuming any town has a shop. If you are staying in a hotel or short-term rental, assume smoking is prohibited and check before you buy — edibles are the pragmatic choice for visitors with no private space. Never carry or consume in Glacier or Yellowstone, national forests, or BLM land: those are federal jurisdiction where state legalization gives you no protection, which is a common and expensive mistake for tourists here.
What changed recently
The 2025 session produced seven signed cannabis bills. SB 27 (eff. July 1, 2025) extends the moratorium on new licenses and 'freezes the footprint' of licensed premises through June 30, 2027, allowing relocations but no new locations; it also removed the medical/adult-use distinction so green counties may sell both types while red counties remain medical-only. SB 11 (eff. April 17, 2025) modified the local ballot process — signature requirements and election timing — by which red counties and municipalities opt in to adult-use sales. SB 74 revised tax rules, basing the 20% adult-use excise tax on retail price after discounts and promotions. HB 49 tightened synthetic cannabinoid rules, and SB 375 prohibits sale of hemp-derived THC products outside the licensed cannabis system unless FDA-authorized. Two changes took effect July 1, 2026: HB 636 cuts the adult-use edible limit to 5 mg delta-9 THC per serving and 100 mg per package, and HB 792 imposes new warning labels, a universal symbol, addiction-resource QR codes, and mandatory dispensary education posters. HB 952 (tribal cannabis compacts) was vetoed by Governor Gianforte. SB 255 (consumer registry and $200 annual fee) and SB 443 (15% THC cap) both failed after public opposition. With the license moratorium running to mid-2027, the 2027 session is expected to be the most consequential for Montana cannabis policy since 2021, including any consumption lounge proposals.
