Are THC Gummies Legal in Montana? Laws, Limits, and Where To Buy (2026 Guide)

By Arthur Cohen, Cannabis Policy Writer | Fact-checked by Linda Hill [Editor]

Browsing a hemp brand’s website from your couch in Missoula and wondering the obvious: Is THC legal in Montana? Yes, but the rules changed in 2025. Updated to reflect Senate Bill 375 and House Bill 49, this guide covers what THC products you can legally buy, who can buy them, and where to buy THC gummies in Montana now that hemp Delta-9 edibles can no longer ship into the state.

Are THC Gummies Legal in Montana?

THC gummies are legal in Montana only when purchased as marijuana products from a state-licensed adult-use dispensary by an adult 21 or older. Hemp-derived THC gummies that ship from out-of-state retailers are no longer allowed under Senate Bill 375, signed in May 2025. 

Federal law still permits hemp-derived Delta-9 under the 2018 Farm Bill, but Montana now restricts what can actually be sold to consumers inside the state. Enforcement is handled by the Montana Department of Revenue Cannabis Control Division.

Hemp-Derived vs. Marijuana-Derived THC Gummies

THC can come from two different plants, and Montana treats them very differently. Knowing which product comes from where helps you decide between a legal buy and a felony exposure.

What Is Hemp-Derived THC?

Hemp is Cannabis sativa L. with no more than 0.3% Delta-9 THC by dry weight, defined under the 2018 Farm Bill. Hemp-derived gummies in compliant states ship across state lines as federally legal agricultural products. In Montana, hemp gummies are now banned at the consumer level if they contain detectable Delta-9.

What Is Marijuana-Derived THC?

Marijuana is Cannabis sativa L. with more than 0.3% Delta-9 THC by dry weight. The Delta-9 molecule is chemically identical regardless of the source plant. Marijuana gummies are restricted to states with medical or adult-use programs and are only sold through licensed dispensaries.

Marijuana-Derived THC Gummy Access in Montana

Recreational marijuana is legal in Montana for adults 21 and older. Voters passed Initiative 190 in 2020, and adult-use sales began on January 1, 2022, under House Bill 701. Medical marijuana has been legal since 2004, with patients 18+ qualifying under conditions like cancer, PTSD, severe chronic pain, MS, and epilepsy. 

Both groups buy from licensed dispensaries tracked through METRC. Hemp gummies, once a workaround for adults in non-cannabis states, are now blocked at retail under SB 375.

Montana Hemp Laws Governing THC Gummies

Montana’s hemp framework was rewritten in the 2025 session. Two bills carry most of the weight.

The 2018 Farm Bill and How Montana Aligned

Montana adopted the federal 0.3% Delta-9 cultivation standard, codified under MCA Title 80, Chapter 18. The state hemp program runs through the Montana Department of Agriculture under a USDA-approved plan, with separate retail rules for finished consumer products.

Senate Bill 375 and House Bill 49 Explained

Senate Bill 375, signed by Governor Greg Gianforte and effective May 5, 2025, bans the sale of any hemp product containing Delta-9 THC to consumers in Montana unless FDA-approved as a food or drug. No mass-market hemp gummy meets that bar.

House Bill 49, signed April 7, 2025, addresses synthetic cannabinoids and tightens product caps. The U.S. Hemp Roundtable confirms the law sets hemp limits at 0.5 mg of THC per serving and 2 mg per package, regardless of variant.

Recent Legislative Activity

House Bill 636, effective July 1, 2026, sets new caps for marijuana edibles at licensed dispensaries: 5 mg per serving, 100 mg per package. Senate Bill 27 also freezes new dispensary licenses through June 30, 2027.

THC Gummy Dosage Limits Under Montana Law

A THC gummy is legal in Montana only at the doses the state allows for the channel it sells through. Hemp and marijuana have completely different ceilings.

The 0.3% Dry Weight Rule, Explained Simply.

A hemp product is federally legal when the total Delta-9 THC stays below 0.3% of the product’s dry weight. Montana follows the federal cultivation standard but layers a stricter retail rule on top.

How Much THC Can a Legal Gummy Contain in Montana?

A 4-gram hemp gummy could legally hold about 12 mg of Delta-9 under the federal 0.3% rule. In Montana, that gummy fails on two counts: HB 49’s 0.5 mg-per-serving cap and SB 375’s ban on the sale of hemp Delta-9.

Montana’s Caps Beyond Federal Law

Hemp gummy retail caps in Montana:

• 0.5 mg THC per serving (HB 49)
• 2 mg THC per package (HB 49)
• Hemp Delta-9 consumer sale banned (SB 375)

Marijuana gummy dispensary caps (effective July 1, 2026, under HB 636):

• 5 mg Delta-9 THC per serving
• 100 mg Delta-9 THC per package

The hemp caps eliminate the 10 mg gummy that national hemp brands sell. Dispensary marijuana gummies are now the only legal route to a real-dose THC gummy in Montana.

Age, Purchase, and Possession Rules in Montana

Montana weed laws set a hard age floor and clear product limits, applied to residents and visitors equally.

Who Can Buy THC Gummies in Montana?

Adults 21+ can buy recreational marijuana gummies from a licensed Montana dispensary with a valid government-issued ID. Patients 18+ with a Montana medical card buy at lower tax rates. Out-of-state medical cards are not recognized for medical pricing, but visiting adults 21+ can buy adult-use products. Online sale of hemp THC gummies in Montana is prohibited under SB 375.

Possession and Travel Rules

Adults can possess up to one ounce of marijuana flower, eight grams of concentrate, or 800 mg of THC in edibles per transaction. Marijuana must travel in sealed packaging in the trunk or a locked compartment, never the passenger area. Crossing into Idaho, Wyoming, or any other state remains a federal violation.

Where to Buy THC Gummies in Montana

THC gummies in Montana can only be bought in person at a state-licensed marijuana dispensary in a green county. Out-of-state hemp brands cannot ship hemp Delta-9 gummies to Montana addresses under SB 375. Opt-in counties include Missoula, Yellowstone, Gallatin, Flathead, Lewis and Clark, and Cascade.

Montana vs. Neighboring States: Where to Buy Legal THC Gummies Online

Adults who travel from Montana to states with hemp-friendly laws can legally buy hemp-derived THC gummies and have them shipped to a delivery address in that state. Two trusted hemp brands meet Farm Bill compliance and ship to most legal states. Buy to a legal state address, and bring nothing back across the Montana state line.

How to Choose a Legal THC Gummy Brand

Four buying criteria for hemp-derived THC gummies:

• Hemp-derived with COA showing total Delta-9 under 0.3% by dry weight
• Third-party lab tested with QR code linking to a batch-specific certificate
• Compliant with the destination state’s hemp packaging and dosage rules
• Clear milligram-per-serving disclosure on the front of the package

1. BudPop: Best Overall Hemp Brand for Out-of-State Delivery

BudPop ships hemp-derived Delta-9 gummies that comply with the 2018 Farm Bill, giving Montana adults 21+ a clean option when traveling to a legal state. The brand uses US-grown hemp in vegan, gluten-free formulas and publishes batch-specific lab reports through a QR code on every package. We tested BudPop’s Fruit Punch batch and confirmed the COA matched front-of-package potency exactly.

Top BudPop picks for adults shopping at a legal state address:

• BudPop Delta-9 THC Gummies: 10 mg per gummy, 30 gummies per bottle, hemp-derived and under the federal 0.3% dry weight threshold.
• BudPop Sleep Gummies (Delta-9 + CBN): formulated for evening use, same hemp compliance standard.
• BudPop Blue Lotus Gummies: pairs blue lotus extract with hemp Delta-9, CBG, and CBN.

BudPop’s most recent COA confirms total THC concentration sits within the 2018 Farm Bill threshold, and the brand restricts shipping to states where hemp Delta-9 is allowed.

2. Exhale Wellness: Top Pick for Premium Hemp Gummies

Exhale Wellness offers hemp-derived Delta-9 gummies that comply with the 2018 Farm Bill, giving adults 21+ a reliable choice for legal-state addresses. The brand uses US-grown hemp, vegan formulations, and batch-level COAs published on every product page. During our review, the published COA matched front-of-package potency claims and showed clean results on heavy metals, pesticides, and residual solvents.

Top Exhale Wellness picks for adults shopping in a legal state:

• Exhale Wellness Delta-9 Gummies (Cubes): hemp-derived Delta-9 cubes, third-party tested, sit under the federal 0.3% dry weight threshold.
• Exhale Wellness Full Spectrum Live Resin Gummies: full-spectrum live resin profile within compliance threshold.

Exhale blocks orders to states where hemp Delta-9 is restricted, keeping Montana addresses out of the cart automatically. Their published COA on every product page makes verification straightforward before purchase.

What to Avoid When Buying THC Gummies for Montana

• Skip gas-station hemp gummies sold without a published COA.
• Ignore Amazon listings claiming to be major hemp brands. Reputable brands rarely list there. 
• Avoid any product without a batch-specific QR code or transparent state shipping policy.

How to Verify a THC Gummy Is Legal in Montana

A legal THC gummy in Montana came from a licensed dispensary. Verifying involves checking the lab report, the packaging, and the seller’s license.

Read the Certificate of Analysis (COA)

Look for total Delta-9 THC and total THC values, percentages by dry weight, a batch ID matching the package, a recent test date, and screening for heavy metals, pesticides, residual solvents, and microbials.

Confirm Montana Packaging Compliance

Marijuana products must come in child-resistant packaging, carry a METRC tracking code, display the universal warning symbol, and include warnings such as “Keep out of reach of children and pets.” Look-alike candy shapes are prohibited.

Verify the Retailer’s License

Cross-check the dispensary against the Montana Department of Revenue Cannabis Control Division licensee list. Hemp retailers selling intoxicating products since May 2025 are operating outside state law.

Penalties for Buying or Possessing Illegal THC Gummies in Montana

Possession of marijuana edibles above the one-ounce usable marijuana equivalent (which includes the 800 mg THC cap on edibles within that ounce) by adults 21+ is a civil infraction up to two ounces, with fines of up to $200 for a first offense, $300 for a second, and $500 for a third or subsequent offense under MCA § 16-12-106.

Possession of more than two ounces is a felony punishable by up to five years in prison and up to a $50,000 fine under MCA § 45-9-102. Possession by anyone under 21 falls under MCA § 45-5-624. Driving with more than 5 ng/mL of Delta-9 THC in blood is a per se DUI under MCA § 61-8-1002, carrying the same penalties as alcohol DUI.

Public smoking of marijuana is a civil fine up to $50, and improper transport in a motor vehicle (outside a sealed container in the trunk or locked compartment) carries a civil fine up to $100. SB 375’s hemp Delta-9 ban primarily targets retail sellers. Consumer-side enforcement is limited. Consult a Montana attorney for specific situations.
