Is CBD Legal? Federal Law, State Rules and 2026 Changes

Is CBD legal? Under federal law, CBD made from hemp is legal when the product meets the legal definition of hemp, which today means no more than 0.3% delta-9 THC by dry weight. CBD from marijuana, or a hemp product above that limit, is a controlled substance. That answer comes with three caveats: the FDA does not allow CBD to be sold as a dietary supplement or added to food, states set their own rules, and a stricter federal hemp definition takes effect on December 11, 2026.

This guide is general information as of September 30, 2026, not legal advice. For a specific product, trip or business decision, check your state regulator or ask a lawyer.

Is CBD legal federally?

Yes, within limits. The Agriculture Improvement Act of 2018, the farm bill signed on December 20, 2018 (Public Law 115-334), removed hemp from the federal definition of marijuana. Federal law defines hemp as the cannabis plant and all of its derivatives, extracts and cannabinoids with a delta-9 THC concentration of not more than 0.3% on a dry weight basis. CBD extracted from plants that meet that definition, in a product that also meets it, falls outside the Controlled Substances Act.

So is hemp legal everywhere in the US? Not automatically: states can add their own rules.

What the DEA says about hemp-derived CBD

The DEA put the farm bill into its regulations with an interim final rule published and effective August 21, 2020. It says:

• Cannabis material with 0.3% or less delta-9 THC by dry weight is hemp and is not controlled.
• A derivative, extract or product that exceeds 0.3% delta-9 THC is a Schedule I controlled substance, even if the plant it came from was under the limit.
• All synthetically derived THC remains in Schedule I, whatever its concentration.
• Nothing in the farm bill changes the FDA’s authority over foods, drugs and cosmetics.

Marijuana itself is still mostly in Schedule I. Effective April 28, 2026, the DEA moved two categories to Schedule III: marijuana in FDA-approved drug products and marijuana covered by a state medical marijuana license. A decision on the rest of marijuana was still pending in late September 2026.

What the FDA says: legal to sell is not the same as approved

The FDA question is separate: the farm bill explicitly kept the FDA’s authority over cannabis-derived products. The FDA’s position:

• Not a dietary supplement. The FDA has concluded that THC and CBD products are excluded from the dietary supplement definition, because CBD is the active ingredient in an approved drug and was studied as a drug first.
• Not a food ingredient. The FDA says it is prohibited to sell food with added CBD across state lines.
• One approved drug. Epidiolex, a prescription CBD oral solution approved on June 25, 2018, is the only FDA-approved CBD drug. Its label covers seizures linked to three rare conditions in patients 1 year and older.
• No new pathway yet. On January 26, 2023, the FDA said its existing food and supplement frameworks are not appropriate for CBD and that it would work with Congress on a new approach.

Over-the-counter CBD products are therefore not FDA-approved or reviewed by the FDA before sale. Our guide to CBD vs THC covers the FDA’s safety statements.

CBD laws 2026: the new federal hemp definition

Congress has rewritten the hemp definition. The dates below match our full guide to the 2026 hemp ban:

• November 12, 2025: P.L. 119-37 was signed. Section 781 measures hemp by total THC, including THCA, still capped at 0.3% by dry weight; limits finished products to 0.4 mg of total THC and THC-like cannabinoids per container; and excludes cannabinoids synthesized or converted outside the plant.
• September 2, 2026: H.R. 6500 was signed, moving the start date for most of the change from November 12 to December 11, 2026.
• November 12, 2026: cannabinoids that the cannabis plant cannot naturally produce still lose hemp status on the original date.
• December 11, 2026: the rest of the new definition takes effect unless Congress acts again.

CBD itself is not banned. What matters is total THC per container and how the cannabinoids were made. A full-spectrum oil can hold far more than 0.4 mg of THC in a bottle while staying under 0.3% by weight, and the Congressional Research Service notes that full-spectrum products above the cap would be controlled as marijuana. Broad-spectrum and isolate products are more likely to fit, depending on testing. Our comparison of full spectrum vs broad spectrum vs CBD isolate explains the difference.

Question	Until December 11, 2026	From December 11, 2026
THC that counts	Delta-9 THC only	Total THC, including THCA
Plant and extract limit	0.3% delta-9 THC, dry weight	0.3% total THC, dry weight
Finished products	Same 0.3% dry-weight test	No more than 0.4 mg total THC per container
Synthesized or converted cannabinoids	Synthetic THC already Schedule I (DEA)	Excluded from hemp (non-natural ones from November 12, 2026)
CBD as a supplement or food additive	Not allowed (FDA)	Not allowed (FDA)

CBD legal states: why there is no single list

Searches for CBD legal states assume a simple yes or no for each state. In reality, states differ on age limits, THC testing, product types, licensing and labels, and they change those rules on their own schedules, unaffected by the federal delay. Two examples from state agency websites, checked September 30, 2026:

• California. According to the California Department of Public Health, emergency regulations effective September 23, 2024 require hemp foods, beverages and dietary supplements for human consumption to contain no detectable total THC, set a minimum purchase age of 21 and limit packages to five servings. AB 8, signed October 2, 2025 with most provisions effective January 1, 2026, regulates intoxicating hemp products as cannabis while keeping CBD and CBN as cannabinoids that may be added to foods.
• Texas. After Governor Abbott’s Executive Order GA-56 of September 10, 2025, the Texas Alcoholic Beverage Commission and the Department of State Health Services adopted emergency rules in September and October 2025 barring sales of consumable hemp products to anyone under 21 and requiring ID checks. DSHS says its adopted rule text took effect March 31, 2026.

Other states have their own THC caps, licenses or product bans, so check the state’s agriculture department, health department or cannabis regulator.

Can you fly with CBD?

For years, the TSA’s medical marijuana page said cannabis products, including some CBD oil, were illegal under federal law except products with no more than 0.3% THC on a dry weight basis or products approved by the FDA. The current page, updated April 27, 2026, no longer mentions CBD. It says TSA officers do not search for illegal drugs, but will refer the matter to a law enforcement officer if any illegal substance is found during screening, and that the final decision rests with the officer. NORML reported in July 2026 that the TSA described its policy as unchanged. The law at your destination still applies, and other countries have their own rules.

Shipping CBD by mail

USPS Publication 52, section 453.37, allows hemp and hemp-based products, including CBD, with THC not exceeding 0.3% to be mailed within the United States, but only when the mailer follows all applicable federal, state and local laws and keeps compliance records, such as lab test results or licenses, for at least 3 years after mailing. Hemp products, including CBD, may not be sent by international mail, including to APO, FPO and DPO addresses. The USPS rule refers to the federal hemp definition “or any successor provision”, so changes to that definition carry over.

Legal does not mean drug-test safe

Legal status and workplace testing are separate questions. Tests look for THC, not CBD, and full-spectrum products contain trace THC. The US Department of Transportation’s CBD notice of February 18, 2020 says CBD use is not a legitimate medical explanation for a laboratory-confirmed marijuana positive, so a positive result for a pilot, truck driver or other safety-sensitive worker stands even if the person says they used only CBD. See our guide to whether CBD shows up on a drug test before using any CBD product if you are tested.

How to check whether a CBD product is likely to comply

• Read the batch certificate of analysis. Look for delta-9 THC, THCA and total THC, and check that the batch number matches the package. Our guide on how to read a CBD certificate of analysis shows where to look.
• Work out THC per container. Multiply THC per serving by the number of servings and compare it with the 0.4 mg cap that starts December 11, 2026.
• Mind the dates. A product bought now may not meet the new definition later. Our guide to whether CBD expires covers shelf life and the hemp-law date.

You can compare spectrum, cannabinoid content and lab reports across our CBD category.
