What the Hemp Just Happened?

THE FEDERAL HEMP BAN AND TENNESSEE

On November 12, 2025, Congress passed—and the President signed—a federal spending bill that includes a sweeping ban on most consumable hemp-derived products that contain THC or similar cannabinoids. I am not yet sure if this is a silver lining that industry can cling to, but in deciding how to approach lawmakers from a policy perspective, we cannot neglect to remember that though the current ban is far from what the hemp industry needs, for the first time, the federal government has clearly stated that there is a “safe” and approved level of THC in hemp-derived cannabinoid products, 0.4 mg per container.  Now, the discussion turns, hopefully, to simply raising this ceiling to a reasonable level that allows industry to thrive is a safe, controlled, regulated manner. 

Here are the key details:

• The 2018 Agriculture Improvement Act of 2018 (“Farm Bill”) had legalized hemp (defined as cannabis with ≤ 0.3% Δ9-THC by dry weight) and opened up a large industry of hemp‐derived CBD and minor cannabinoids. 
• The new law revises the definition of hemp in three important ways: 1) It expands “total THC” definition to include Δ9-THC and THCA and other tetrahydrocannabinols combined.  2) It prohibits hemp-derived cannabinoid products that are “synthesized or manufactured outside the plant” or where the cannabinoid was not naturally occurring in the plant. 3) It sets a container‐level cap: no more than 0.4 mg of “THC or similar effect” cannabinoids per container for hemp to qualify.
• The law is not immediately effective: it provides about a one-year implementation window, allowing industry to wind down, pivot, sell through products, or, hopefully, enact a regulatory framework in Congress which is a repeal of the prohibition on intoxicating hemp with framework with which the states can build upon. 
• The change is being justified as closing a “loophole” in the 2018 law that allowed the commercialization of intoxicating hemp‐derived products (e.g., Δ8-THC edibles, drinks) that avoided the marijuana thresholds. 

Why This Matters – Industry Members

During its 2025 legislative session, the Tennessee General Assembly enacted arguably the most comprehensive framework for the manufacture, distribution and sale of hemp-derived cannabinoid products in the country in the form of Public Chapter 526.  This framwork, set to implement on January 1, 2025, has already begun to clean up the marketplace in Tennessee in favor of legitimate, regulated products, and has resulted in robust business planning and investment for industry members looking to thrive in a tightly regulated legal framework here in Tennessee.

What occurred this week in D.C. is a seismic shift.  Understanding that that the law, if left without revision in 2026, will wipe out a large portion of the consumable hemp products market. One estimate cited in media said the change could eliminate 95% of hemp ingestibles. Farmers, especially in states with large hemp production (e.g., Kentucky), say the timing is cruel and unsettling. Retailers and manufacturers of hemp-derived products (edibles, vapes, drinks, other cannabinoid products) face a future where many of their existing products may no longer qualify as “hemp” under federal law—instead becoming controlled substances.  Further, there are many significant ripple effect unknowns, such as, how the insurance providers that will currently underwrite hemp businesses will analyze their risk factors, even before November 2026 when the ban goes into effect.  Will we begin to see a flood of policy cancellation notices transmitted well before the ban goes into effect, essentially forcing legitimate industry members to take enormous risk to even sell through inventory, leaving other, more risk-taking industry members to join a “race to the bottom” for the sale of banned hemp-derived products.

For Consumers

Some non-intoxicating CBD products may also be impacted. Although the law is intended to preserve non-intoxicating CBD and industrial hemp, because of the tight cap and the new definitions there’s concern that many CBD products may exceed the container cap or have trace cannabinoids that will push them out of compliance.
From a regulatory/law enforcement standpoint, this changes the landscape: many products once marketed and sold freely may now be classified as controlled, which has implications for testing, shipping, interstate commerce, enforcement, retail licensing, etc.

What Are the Next Steps

Here are what stakeholders should be watching and doing in the coming months:

1. Regulatory rulemaking
   • Agencies will likely publish lists of cannabinoids “known to be naturally produced by Cannabis sativa L.” and those with “similar effects” to THC. 
   • State regulators will need to update their hemp programs (which often mirror or reference federal definitions) to reflect the federal change.
   • Testing and compliance standards will need to adjust: measuring total THC (Δ9 + THCA) rather than just Δ9; measuring container-level mg limits; identifying synthetic/semi-synthetic cannabinoids.
2. Industry alignment & legal strategy
   • Hemp businesses (farmers, manufacturers, retailers) should audit their product lines now to see what may fall out of compliance under the new law.
   • Some companies may shift focus to industrial hemp (fiber, seed) or non-cannabinoid uses rather than consumables.
   • Legal challenges may emerge—questions around vagueness (e.g., which cannabinoids count as “similar effect”), non‐delegation (agency power), and whether semi-synthetic cannabinoids should be banned. 
   • Advocacy for new legislation: Because the law gives a ~1-year phase-in, there is a window for Congress to enact alternative regulatory frameworks (instead of outright prohibition) for hemp-derived cannabinoid products. 
3. State & local policy response
   • States that have robust hemp markets will face pressure: either adjust state law/regulation or face conflict with federal definitions. Some states may try to maintain looser definitions until federal law fully kicks in.
   • Retailers and distributors will need to watch for enforcement shifts (federal, state) and adjust supply chains accordingly.
   • Consumers should anticipate some products being pulled or reformulated, and possibly higher compliance costs being passed down.
4. Market & business adaptation
   • Companies may pivot: e.g., focusing on truly non-intoxicating CBD products (that have no THC or extremely low THC), or focus on non‐ingestible forms (topicals) which may be less impacted.
   • Some may exit consumables entirely and move back toward industrial hemp applications (textiles, building materials, bio‐ composites).
   • Product innovation will likely slow or shift into regulatory-safe zones (e.g., zero THC, non-converted cannabinoids).

Key Questions & Watchpoints

• What exactly counts as a “cannabinoid with similar effects to THC” and who defines it? The law empowers HHS/other agencies to make this determination.
• What happens to consumption, possession and interstate transport of products once the law kicks in? If a product no longer qualifies as hemp, it may be classified as marijuana/controlled substance under federal law—raising enforcement risks.
• How will state hemp programs respond? States have varying regulatory regimes; alignment (or mis-alignment) could create confusion and legal risk.
• What will the regulatory timeline look like? Although there is roughly a year until the new definition takes full effect, product development, testing infrastructure, certification, and regulatory updates may take longer.
• Will Congress step in with a new framework? Industry advocates and some lawmakers hope to propose legislation to replace the upcoming ban with regulated, age-restricted, tested market for hemp-derived consumables.

Conclusion

The inclusion of a broad ban on many hemp-derived THC and minor cannabinoid products in the 2025/2026 federal spending bill marks a sharp pivot in U.S. federal hemp policy. What began as the legalization of hemp under the 2018 Farm Bill has now been substantially rolled back for consumables.

For the hemp industry, consumers, and regulators alike, the next 12 months will be critical. The window allows time for adjustment—but also raises uncertainty. Businesses must prepare, regulators must act, and policymakers may yet decide whether this new path is the best one for balancing public health, consumer access, innovation, and agriculture.
