In November 2025, the U.S. government passed a major federal spending bill. The bill was intended to help reopen the government—but tucked inside was one of the most significant changes to hemp regulation since 2018. The new language enacted through H.R. 5371, Section 781 places THC limits on hemp and reshapes how CBD, Delta-8, Delta-9, and other hemp-derived products will be regulated going forward.
For consumers, small business owners, and hemp manufacturers, this marks a turning point. The updated law aims to close loopholes around hemp products, but it also introduces new compliance challenges and uncertainty that may affect many of the CBD products you currently use.
Let’s take a closer look at what the 2025 federal hemp legislation does, how it impacts CBD, and what steps you can take to ensure the CBD/THC products you love remain available.
What Does the 2025 Federal Hemp Law Change?
The new legislation introduces three major updates that affect CBD legality, total THC rules, and the future of hemp-derived cannabinoids.
1. Hemp is now defined by total THC—not just Delta-9
The 2018 Farm Bill allowed for hemp that contained no more than 0.3% Delta-9 THC by dry weight to be used in CBD products. Under the updated statute, raw hemp must contain no more than 0.3% total THC by dry weight. This change affects hemp farmers, pushing them to lean into industrial hemp strains that meet the new lower THC limit.
This focus on total tetrahydrocannabinols (not just delta-9 THC) closes the technical gap that previously allowed some plants and products to be marketed as hemp even though they could yield psychoactive cannabinoids after processing.
2. New THC limits for finished CBD and hemp-derived products
For the first time, federal law sets a per-container THC cap of 0.4 mg total THC per product. This very low per-container cap would effectively make most current CBD/THC beverages, gummies, and Full Spectrum tinctures illegal as of November 2026.
3. USDA, FDA, and DEA will oversee implementation
The new statute gives federal agencies (notably DEA, HHS, USDA, and FDA) roles in defining which cannabinoids count toward the THC limit and how a “container” is interpreted. In addition, agencies are expected to issue guidance on:
– How total THC must be calculated
– How products will be tested and labeled
– Enforcement priorities
– Whether states will receive flexibility or variance

How Do New THC Limits Affect My CBD Purchases?
New limits on THC may require brands to reformulate their products using hemp strains with less total THC, offer smaller packages to adhere to the 0.4 mg of THC per package limit, or remove natural trace cannabinoids, which minimizes the entourage effect of Full Spectrum CBD products. Here are some specific ways current CBD offerings will be affected:
Full Spectrum CBD Oil
Many will exceed the new 0.4 mg/container THC limit, even at federally legal hemp potencies. This means bottles of Full Spectrum CBD oil will likely be smaller in size, so you’ll need to purchase more bottles for a monthly supply.
Broad Spectrum CBD Oil
Broad Spectrum CBD is formulated without THC, and shouldn’t be affected by the 2025 Federal hemp legislation.
CBD Isolate
CBD Isolate is formulated without THC, and shouldn’t be affected by the 2025 Federal hemp legislation.
CBD Gummies
Many CBD gummies contain 2–5 mg THC per serving. Under the new rules, these would no longer qualify as hemp. Full Spectrum gummies may also be at risk due to total THC per package, requiring smaller packaging. Broad Spectrum and Isolate gummies shouldn’t be affected.
Delta-8 and Delta-9
These products in all their forms are the primary target of the legislation. Because they are psychoactive, they will face significantly tighter restrictions at the federal level, even in states where they remain legal today.
THCA Flower
Because THCA now counts toward total THC, nearly all THCA flower will no longer meet the federal hemp definition.
A Note About Online CBD Orders
In addition to product reformulations and packaging changes, the CBD industry faces challenges with interstate commerce. If you currently order CBD products online, you could run into the following problems next November:
Retail availability & interstate commerce: Products that exceed the new per-container THC limit would be inconsistent with the federal hemp definition and could be treated as controlled substances under federal law. This could create severe limits on shipping and sale across state lines between states where marijuana is legal vs. states where it is not.
Testing, labeling, and reformulation: Manufacturers will need to test for total THC (including isomers and THCA) and likely rework formulations, packaging, and labels to meet both the 0.3% dry-weight field test and the new 0.4% per-container limit. This could affect costs and disrupt supply chains.
State patchwork persists: States that have already regulated intoxicating hemp products (or legalized adult-use marijuana) will respond differently. Some may align with the federal change, others may push back or pursue litigation. That means the legal landscape will remain murky.
What Can I Do to Change CBD Regulations?
CBD is still legal, but the range of available CBD products is likely to shrink unless Congress adjusts the law. To voice concerns or support reform, contact your federal representatives using the official tools and sample message listed below. It’s not too late to make your voice heard!
How to contact elected officials
Use these official tools:
House of Representatives “Find Your Rep” – enter your ZIP code
U.S. Senate Directory – list of Senators by state
USA.gov “Contact Elected Officials” – phone, email, and mailing details
Sample message
“Hi, I’m a constituent in [your city]. I’m calling about the hemp amendment included in H.R. 5371, Section 781. I’m concerned that the new 0.4 mg per-container THC limit and inclusion of total THC will eliminate many safe, tested hemp products and hurt local businesses and farmers. Please tell me what specific actions the Senator/Representative plans to take to protect access to regulated CBD and to protect local jobs. Thank you for supporting adjustments to the 2025 federal hemp legislation.”
Why the 2025 Hemp Law Matters
This legislation marks the biggest rewrite of U.S. hemp policy since the Farm Bill legalized industrial hemp in 2018. With the new total THC limits and agency oversight, the landscape of CBD products will shift considerably in November 2026.
Whether you’re a consumer who relies on CBD, a retailer, a manufacturer, or a farmer, now is the time to stay informed. Review the COAs (Certificates of Analysis) for products you use to understand their THC levels and know if they will be affected by the new legislation. Engage with your representatives and let them know you want these products to continue to be available.
Summary
CBD isn’t going away, but the federal rules governing it are transforming quickly. Many popular hemp products face a one-year countdown to a new federal standard that will dramatically restrict or outlaw them nationwide unless Congress, the courts, or regulators change course.
This change means hemp grown for use in CBD products will be limited to how much total THC it contains, and CBD products will be limited to how much total THC is allowed per container.
For many consumers, the Full Spectrum CBD, Delta-8, and Delta-9 products they rely on will no longer be available except in states where marijuana is legal. Broad Spectrum CBD and CBD Isolate products will likely not be affected.
