The Farm Bill Loophole Is Closing: What It Means for Hemp-Derived THC

The Farm Bill loophole that made hemp-derived THC products legal across America is officially closing. In November 2025, President Trump signed the Continuing Appropriations Act, 2026 (P.L. 119-37), which rewrites the federal definition of hemp and bans most intoxicating hemp products. The change starts November 12, 2026, and it affects anyone who frequently purchases Delta-8 THC, THCa, or hemp-derived THC products. But there’s a lot of misinformation floating around at the same time. This article breaks down what the new restrictions say, how they differ from the original bill, and what to expect over the next year.

The Farm Bill loophole was closed through the Continuing Appropriations Act, 2026, signed on November 12, 2025, not through a new Farm Bill New restrictions redefine hemp using total THC (including THCA, delta-8, delta-10, etc.) instead of just delta-9 THC Finished hemp products are capped at 0.4 milligrams of combined total THC per container; this would exclude about 95% of current products Synthetic and lab-converted cannabinoids like delta-8 THC are now explicitly excluded from the definition of hemp Enforcement begins November 12, 2026, giving the industry one year to adapt, lobby for changes, or shut down State-legal recreational and medical cannabis programs remain unaffected

The original Farm Bill loophole came from the Agriculture Improvement Act of 2018 (commonly called the 2018 Farm Bill). This defined hemp as cannabis containing less than 0.3% delta-9 THC by dry weight, and it allowed farmers to grow it for fiber, grain, and non-intoxicating CBD products. The problem? The law only mentioned delta-9 THC. It said nothing about other cannabinoids like delta-8, delta-10, THCA, or HHC. Companies quickly realized they could extract CBD from legal hemp, convert it into intoxicating compounds, and sell these products nationwide. This loophole in the Farm Bill created a massive, unregulated cannabis market. THC gummies, vapes, beverages, and THCA flower flooded gas stations, smoke shops, and online stores in states where recreational cannabis remained illegal. The loophole was so gaping that industry estimates put the market value at $28 billion annually. Lawmakers, state attorneys general, and traditional cannabis operators pushed back. In October 2025, a bipartisan coalition of 39 state and territory attorneys general sent a letter to Congress urging them to close the Farm Bill loophole. They noted two concerns: unregulated products reaching minors and the lack of safety testing. The new Farm Bill update that many expected didn’t come through as a standalone bill. Instead, Congress attached hemp restrictions to the must-pass government funding package needed to end the longest government shutdown in U.S. history. The Continuing Appropriations Act, 2026 (H.R. 5371), signed November 12, 2025, included Section 781, which rewrites the federal definition of hemp entirely.

Here’s exactly what to expect from the new law. Redefines hemp using total THC, not just delta-9 THC. The 0.3% threshold now applies to total tetrahydrocannabinol concentration, including THCA, delta-8, delta-10, and all other THC isomers and analogs. This immediately reclassifies most THCA flower and similar products as marijuana under federal law. Caps finished products at 0.4 mg total THC per container. This is the most devastating change for consumers. A typical hemp gummy has 2.5 to 10 mg of THC. However, the new federal limit is 0.4 mg per container, not per serving. Industry groups estimate this would remove 95% of available hemp products, including many full-spectrum CBD products. Bans synthetic and converted cannabinoids. Any cannabinoid that isn’t naturally produced by the cannabis plant, or that was synthesized or manufactured outside the plant, does not fall under the definition of hemp. This directly targets delta-8 THC, delta-10, THC-O, HHC, and similar compounds made by chemically converting CBD. Preserves industrial hemp. The law still protects “industrial hemp”—plants grown for fiber, grain, seed, or research. Non-cannabinoid uses of hemp remain legal. Requires FDA action within 90 days. The FDA must publish lists of all naturally occurring cannabinoids, THC-class cannabinoids, and other compounds with similar effects to THC. They must also clarify the definition of “container.” What the new restrictions don’t mean: They don’t suddenly make THC illegal in states with recreational cannabis programs. Dispensary products in legal states will stay unaffected. They don’t ban all CBD. Low-THC CBD isolate and products meeting the 0.4 mg threshold could stay legal, though the U.S. Hemp Roundtable says over 90% of current CBD products exceed this limit. They don’t take effect immediately. Enforcement begins November 12, 2026, creating a one-year window before the Farm Bill loophole closes.

The new restrictions create ripple effects across every part of the hemp supply chain. Businesses built entirely around psychoactive cannabinoids face near-total collapse. Brands selling delta-8 vapes, THCA flower, and THC beverages have one year to either reformulate products, pivot to state-licensed cannabis markets (where possible), or shut down entirely. Jobs across the industry are at risk. Industry estimates suggest around 300,000 American jobs are threatened in the $28 billion hemp economy, including those in manufacturing, extraction, retail, shipping, marketing, and more. In Texas, industry analysis projects up to 40,000 job losses and $7.5 billion in economic impact if intoxicating compounds are banned. Consumers will see dramatically reduced availability and fewer product options. The products that were accessible, affordable, and legal across all 50 states will disappear from shelves by late 2026. Retailers like gas stations, smoke shops, convenience stores, and online sellers will lose a core revenue stream. In Minnesota, more than 5,300 retailers hold licenses to sell hemp-derived edibles and beverages. Many built business models around these specific products. State tax revenue takes a hit. Hemp-derived THC played a major role in states without legal cannabis programs, generating significant tax income. States could lose an estimated $1.5 billion in combined tax revenue. Legal cannabis markets may see some consumers return. But the picture is complicated. Some cannabis operators supported closing the Farm Bill loophole to remove unregulated competition, while others worry about the federal crackdown on cannabinoid products. Black market risk increases when legal channels close but demand remains. Critics back this up, warning that a sudden prohibition will revive illicit sales. Consumers who relied on the Farm Bill loophole to access THC products may seek underground sources when the legal market is gone.

Whenever new restrictions pass, people immediately start looking for workarounds. Is there another Farm Bill loophole in the future? The honest answer: probably not in any meaningful way. The lawmakers wrote the new law specifically to close the gaps that the 2018 version left open. A few theoretical cracks exist, but none are likely to sustain the market as it currently operates: The “container” definition remains undefined. The FDA must clarify what counts as a container, as creative packaging could find a way around it. But this would be a short-term play at best—regulators would likely close any obvious workarounds quickly. State-only intrastate markets might survive in a limited form. Some states could attempt to maintain intrastate-only markets that don’t involve interstate commerce. However, federal enforcement can still target manufacturers, distributors, and retailers operating within those states, making this a legally risky approach. Legislative amendments are still possible before the November 2026 enforcement date. Several lawmakers have already introduced bills to delay or modify the restrictions (more on this below). If Congress acts, some version of hemp-derived products could remain legal—but that’s a political question, not a Farm Bill loophole. Low-dose products under 0.4 mg per container would technically comply with the new law. But at such low concentrations, they’d offer mild effects. Some brands may try to market “compliant” microdose products, but consumer interest in 0.4mg gummies will be limited. For most buyers and retailers, the realistic expectation is that the hemp-derived THC market built on the Farm Bill loophole ends in November 2026 unless Congress revises the law.

The one-year implementation window matters. Enforcement doesn’t begin until November 12, 2026, which means: Products remain legal for now. Hemp-derived THC products can still be manufactured, sold, and purchased throughout 2026 up to the end date. Don’t panic-buy based on misinformation claiming products are already illegal. Legislative challenges are already underway. In January 2026, bipartisan lawmakers introduced the Hemp Planting Predictability Act, which would delay the ban by two years (until November 2028) to give farmers and businesses time to adjust. Similar bills have been introduced in both the House and Senate. Whether any of these efforts succeed depends on political dynamics. Since 2026 is a midterm election year, candidates in hemp-heavy states will absolutely face pressure to support the industry. The 2018 Farm Bill itself is up for reauthorization in 2026. Congress must pass a new farm bill (or another extension) by September 30, 2026. Hemp advocates can attempt to attach amendments that either revert it to the 2018 definition or create a less restrictive framework. This is likely the best realistic chance to preserve some version of the legal hemp market. Full-spectrum CBD faces uncertainty. President Trump’s December 2025 executive order acknowledged that some full-spectrum CBD products will be reclassified as marijuana under the new THC limits. We will have to wait and see whether this leads to exemptions for non-intoxicating wellness products.
