Montana's cannabis and hemp landscape underwent a dramatic transformation in 2025, with the enactment of House Bill 49 (HB 49) establishing some of the nation's most restrictive THC limits for hemp-derived products. Signed into law by Governor Greg Gianforte on April 7, 2025, and effective immediately, this legislation caps hemp products at just 0.5 mg of delta-9 THC per serving and 2 mg per package—limits so stringent they effectively eliminate most intoxicating hemp beverages, gummies, and edibles from the Montana market.
Understanding Montana's Twin-Track Hemp Strategy
While Montana HB 49 focused specifically on synthetic cannabinoids and hemp mg caps, it worked in tandem with Senate Bill 375, which banned the sale of all hemp products containing any detectable amount of THC unless approved by the FDA. Together, these measures represent a comprehensive effort to curtail the intoxicating hemp market while preserving access to non-intoxicating CBD and CBG products.
The legislative strategy appears designed to channel consumers toward Montana's regulated adult-use cannabis dispensaries, which operate under entirely different parameters. Under House Bill 636, also passed in 2025 but effective July 1, 2026, adult-use dispensaries can sell marijuana-infused edibles containing up to 100 mg of delta-9 THC per package with 5 mg per serving—a stark contrast to hemp's 2 mg package limit.
What Still Qualifies Under HB 49's Caps
Despite the restrictive limits, certain hemp products can still legally operate within Montana's new framework:
Ultra-Low Dose Products
- Microdose edibles: Single gummies or chocolates containing 0.5 mg THC or less
- CBD-dominant products: Items with 15:1 or higher CBD:THC ratios
- Topical applications: Creams and salves that don't exceed 2 mg THC per container
- Tinctures: Dropper bottles with extremely diluted formulations
Exempt Categories
Crucially, HB 49 does not apply to unadulterated hemp flower that hasn't been processed into extracts, infused products, or concentrates. This creates a narrow pathway for raw hemp flower sales, though practical intoxicating effects would be minimal given the 0.3% delta-9 THC federal limit.
Compliance Packaging Requirements
Products meeting the THC limits must still comply with Montana's enhanced packaging and labeling standards established under the bill:
- Child-resistant packaging for all hemp products
- Clear THC content labeling per serving and per package
- Warning labels about psychoactive effects
- Ingredient disclosure requirements
- Batch tracking for regulatory oversight
Adult-Use Cannabis vs. Hemp: A Tale of Two Markets
Montana's approach creates a clear regulatory divide between hemp and adult-use cannabis products, with vastly different potency allowances and oversight mechanisms.
Adult-Use Cannabis Advantages
- Higher potency limits: 100 mg THC per package vs. 2 mg for hemp
- Established testing protocols: Comprehensive laboratory analysis requirements
- Professional oversight: Licensed dispensary staff and regulatory compliance
- Product variety: Full spectrum of flower, concentrates, edibles, and topicals
- Quality assurance: Stricter manufacturing and safety standards
Hemp Market Constraints
- Severely limited potency: 0.5 mg serving/2 mg package maximums
- Narrow product categories: Most beverages and traditional edibles eliminated
- Uncertain enforcement: New regulatory framework still being implemented
- Market consolidation: Many existing products now non-compliant
Interstate Commerce and Cross-Border Challenges
The question of whether out-of-state hemp companies can legally ship products into Montana under the new regulations presents significant legal and practical challenges.
Federal vs. State Jurisdiction
While the 2018 Farm Bill established federal hemp legality, states retain authority to impose their own restrictions. Montana's laws now create several barriers:
Legal Barriers:
- Any hemp product shipped into Montana must comply with both HB 49's THC limits and SB 375's FDA authorization requirements
- Products exceeding 0.5 mg THC per serving are prohibited regardless of origin state laws
- Interstate shipping companies may refuse to transport products due to liability concerns
Practical Challenges:
- Payment processing: Credit card companies increasingly scrutinizing hemp transactions
- Shipping logistics: Major carriers implementing their own hemp product restrictions
- Insurance coverage: Liability policies may exclude non-compliant product shipments
- Border enforcement: Montana authorities can seize non-compliant products at entry points
E-commerce Compliance Strategies
For companies attempting to serve Montana customers, several approaches may provide limited pathways:
Ultra-Low Dose Formulations:
- Reformulating existing products to meet 0.5 mg serving limits
- Creating Montana-specific product lines
- Implementing robust age verification and shipping restrictions
CBD-Focused Offerings:
- Emphasizing non-intoxicating hemp products
- Clear labeling of THC content well below legal limits
- Third-party lab testing documentation
Risk Matrix for Retailers and Brands
High-Risk Activities
- Selling non-compliant products: Immediate legal liability and potential criminal charges
- Interstate shipping violations: Federal commerce law complications
- Inadequate labeling: Consumer safety violations and regulatory penalties
- Age verification failures: Sales to minors carry severe penalties
Medium-Risk Areas
- Inventory transitions: Existing stock may become non-compliant overnight
- Testing protocol gaps: Laboratory analysis requirements still being clarified
- Banking relationships: Financial institutions may terminate accounts
- Insurance coverage: Policies may exclude hemp-related activities
Lower-Risk Approaches
- CBD-only products: Non-intoxicating formulations with minimal regulatory risk
- Compliant ultra-low dose items: Products clearly meeting THC limits
- Raw hemp flower: Unprocessed products exempt from serving size restrictions
- B2B wholesale: Selling to licensed Montana cannabis businesses
Market Impact and Industry Response
The implementation of HB 49 has triggered significant market consolidation in Montana's hemp sector. Industry trackers report that approximately 80-90% of existing hemp THC beverages and gummies no longer comply with the new limits, forcing manufacturers to either reformulate products or exit the Montana market entirely.
Beverage Industry Hit Hardest
Hemp-derived THC beverages, which typically contain 2.5-10 mg of THC per serving, face near-complete elimination from Montana retail shelves. Popular formats like:
- THC seltzers (usually 2.5-5 mg per can)
- Cannabis-infused sodas (typically 10 mg per bottle)
- Hemp cocktail mixers (often 5-10 mg per serving)
- Functional beverages (commonly 2.5 mg THC with CBD)
All fall well above the 0.5 mg serving limit, creating a massive market gap that adult-use dispensaries are positioned to fill.
Retailer Adaptation Strategies
Montana retailers are implementing various approaches to navigate the new regulatory environment:
Product Mix Pivots:
- Expanding CBD-only product selections
- Introducing microdose edible lines
- Partnering with compliant manufacturers for private labeling
- Developing Montana-specific product formulations
Compliance Infrastructure:
- Enhanced inventory tracking systems
- Staff training on new THC limits
- Updated point-of-sale systems for regulatory reporting
- Strengthened age verification protocols
Federal Implications and Precedent Setting
Montana's restrictive approach may serve as a model for other states considering similar hemp regulations. The 0.5 mg serving/2 mg package limits represent some of the lowest in the nation, potentially influencing federal policy discussions around hemp product standardization.
Comparison with Other States
Montana's limits are significantly lower than most state regulations:
- Colorado: 2 mg THC per serving for hemp products
- California: 0.5 mg THC per serving (similar to Montana)
- New York: 3 mg THC per serving for hemp beverages
- Vermont: 1 mg THC per serving limit
This positioning places Montana among the most restrictive states for hemp THC products, alongside states like Idaho and South Dakota that have implemented near-total bans.
Looking Forward: Enforcement and Evolution
As Montana begins implementing these new regulations, several key factors will determine their long-term impact:
Enforcement Mechanisms
The Montana Department of Revenue's Cannabis Control Division has been tasked with overseeing hemp product compliance, but specific enforcement protocols are still being developed. Key areas of focus include:
- Retail inspections: Regular compliance checks at hemp retailers
- Laboratory testing: Verification of THC content claims
- Interstate commerce monitoring: Tracking products shipped into Montana
- Consumer complaint investigations: Responding to potential violations
Potential Legal Challenges
Industry groups may challenge the constitutionality of Montana's hemp restrictions, particularly regarding interstate commerce implications. The Commerce Clause of the U.S. Constitution could provide grounds for federal court intervention if Montana's laws are deemed to unduly burden interstate trade.
Market Evolution Scenarios
Several outcomes are possible as Montana's hemp market adapts:
Scenario 1: Consolidation and Compliance
- Manufacturers successfully reformulate products to meet new limits
- Market stabilizes around ultra-low dose offerings
- Consumer acceptance of microdose products grows
Scenario 2: Market Migration
- Consumers shift purchasing to neighboring states with less restrictive laws
- Online sales to Montana residents increase despite legal uncertainties
- Black market activity potentially rises
Scenario 3: Adult-Use Cannabis Growth
- Consumers transition from hemp products to licensed dispensary offerings
- Adult-use cannabis sales increase significantly
- Hemp market becomes primarily CBD-focused
Strategic Recommendations for Industry Stakeholders
For Hemp Manufacturers
- Develop Montana-compliant formulations immediately to maintain market access

- Stay informed about evolving regulations through official state channels
Montana's implementation of HB 49 represents a watershed moment in state hemp regulation, establishing precedent-setting THC limits that prioritize consumer safety while effectively channeling demand toward the regulated adult-use cannabis market. The 0.5 mg serving/2 mg package caps create a narrow but viable market for ultra-low dose hemp products while eliminating most traditional intoxicating hemp offerings.
For businesses operating in or selling to Montana, compliance with these new regulations isn't optional—it's essential for continued legal operation. The interstate commerce implications remain complex, but the safest approach for out-of-state companies is to ensure all products shipped to Montana consumers meet or exceed the state's restrictive requirements.
As other states watch Montana's regulatory experiment unfold, the success or failure of this approach may influence nationwide hemp policy discussions. Whether Montana's strategy effectively achieves its public health and safety objectives while maintaining a viable hemp industry will likely determine its adoption elsewhere.
