Federal Legalization Could Open Interstate Market for Michigan Cannabis

Interstate Commerce Provision Central to Pending Bill

The draft federal legalization framework includes explicit language permitting licensed cannabis businesses to ship products across state lines, a departure from the current state-siloed regulatory model. Michigan cultivators—who've faced steep price compression due to local oversupply—could access out-of-state markets where demand exceeds production capacity.

Michigan's adult-use market has seen wholesale flower prices decline 40% since 2024. A cultivation license surge outpaced retail infrastructure buildout. Interstate commerce would let growers compete in undersupplied states like New York and New Jersey.

Proposed Federal Tax Structure

The legislation contemplates a hybrid federal excise tax combining a per-ounce levy with an ad valorem component tied to retail price. Draft language suggests a $50-per-ounce tax on flower and proportional rates for concentrates and edibles, alongside a 10% federal sales tax.

The framework mirrors alcohol regulation under the Federal Alcohol Administration Act, with the Treasury Department's Alcohol and Tobacco Tax and Trade Bureau (TTB) designated as the lead regulatory agency. This tax structure would layer atop existing state excise taxes, which range from 10% in Michigan to 37% in Washington.

Michigan Market Dynamics

Michigan currently operates 1,100 active cultivation licenses producing an estimated 2.4 million pounds of cannabis annually, far exceeding the state's 800,000-pound consumption capacity. Oversupply has driven wholesale prices below $1,000 per pound in some transactions, down from $2,500 in 2023.

Michigan's cultivation infrastructure is built for a market three times the size of its current consumer base—interstate commerce would let that capacity find buyers.

Major Michigan MSOs including Skymint and Gage Cannabis have signaled interest in interstate expansion, though regulatory details remain unresolved. The state's Cannabis Regulatory Agency hasn't issued guidance on how state licensing would interface with federal interstate permits.

Regulatory Framework and Agency Jurisdiction

The draft bill assigns primary enforcement authority to TTB, with coordination roles for the Drug Enforcement Administration (DEA) and Food and Drug Administration (FDA). The DEA would retain jurisdiction over diversion and criminal enforcement. FDA would regulate labeling, health claims, and product safety standards.

Key unresolved questions include:

• Whether states can block interstate shipments into their jurisdictions
• Licensing reciprocity mechanisms between state and federal permits
• Testing and quality-control harmonization across state programs
• Banking access and Federal Deposit Insurance Corporation (FDIC) coverage for interstate operators

Tax Revenue Projections and Distribution

Congressional Budget Office estimates place federal cannabis tax revenue at $8-12 billion annually once interstate markets stabilize. The draft legislation allocates 60% of revenue to general Treasury funds, 25% to state-level substance-abuse programs, and 15% to social-equity grants for communities disproportionately impacted by prohibition.

Michigan would retain its existing 10% excise tax and 6% sales tax on cannabis transactions. Federal taxes would add an estimated 18-22% to final consumer prices depending on product category.

Industry Reaction and Lobbying Positions

The National Cannabis Industry Association supports the interstate-commerce provision but has called for lower federal tax rates, arguing the combined state-federal burden could exceed 40% in high-tax jurisdictions. Michigan-based trade group MiCannabis has endorsed the framework, citing the need for market expansion to absorb existing production capacity.

Opposition has emerged from state-level regulators in California and Colorado, where established markets fear price competition from lower-cost producers in Michigan and Oklahoma. California's Department of Cannabis Control hasn't taken a formal position but has privately expressed concerns about interstate dynamics undermining local tax bases.

Timeline and Legislative Path

The draft language is expected to be introduced as standalone legislation in September 2026, with committee hearings scheduled for early October. Senate Majority Leader has indicated the bill could reach the floor for a vote before year's end, though passage remains uncertain given opposition from some Republican members.

If enacted, the law would include a 24-month implementation window during which TTB would issue regulations, establish licensing frameworks, and coordinate with state agencies. Interstate commerce wouldn't commence until federal licensing infrastructure is operational, likely no earlier than 2028.
