Where Is CBD Legal in the United States? Cannabis, Hemp, and CBD Laws (2026)

Hemp-derived cannabidiol (CBD) is legal across most of the United States today. Under federal law, CBD made from hemp (cannabis containing no more than 0.3% THC) is not a controlled substance, which is why CBD oils, gummies, and topicals are sold in pharmacies, grocery stores, and gas stations nationwide. CBD made from marijuana is treated very differently, and it is legal only in states that have approved medical or adult-use cannabis.

CBD’s legal status feels confusing because it sits across three bodies of law at once: the federal hemp statute, the U.S. Food and Drug Administration’s product rules, and a state-by-state patchwork. A federal spending law signed in November 2025 added a fourth layer by rewriting the definition of hemp itself, with the changes set to take effect on November 12, 2026.

This guide explains where CBD stands now, what the 2026 changes will do, and how to buy and travel with CBD without running into trouble. Plenty of people reach for CBD as part of an everyday routine for calm and sleep, but the rules around it are still moving. Treat this as general information rather than legal advice, and check your state’s current rules before buying or selling CBD products.

Is CBD Legal in the United States Right Now?

Yes. Hemp-derived CBD that contains no more than 0.3% delta-9 THC is legal under federal law and is sold in nearly every state. Whether any given product is legal comes down to two questions: what plant the CBD came from, and how much THC the finished product contains.

The dividing line was set by the 2018 Farm Bill, which removed hemp from the list of federally controlled substances. CBD extracted from hemp is therefore legal to produce and sell at the federal level. CBD extracted from marijuana is still a controlled substance federally and is available only through state-licensed medical or adult-use cannabis programs.

Two caveats matter. The FDA still prohibits adding CBD to food, drinks, or dietary supplements, even when the CBD itself is hemp-derived. And a handful of states set stricter THC limits or restrict specific CBD products, so “legal under federal law” does not always mean “legal everywhere.”

How the 2018 Farm Bill Made Hemp-Derived CBD Legal

Hemp-derived CBD became legal because Congress carved hemp out of the federal definition of marijuana. Before that, all cannabis was off-limits.

From 1970 onward, the Controlled Substances Act treated cannabis and everything in it, including CBD, as a Schedule I drug with no accepted medical use. The 2014 Farm Bill cracked the door open by letting states run industrial-hemp research programs. The decisive shift came with the Agriculture Improvement Act of 2018, better known as the 2018 Farm Bill, which defined hemp as cannabis with no more than 0.3% delta-9 THC on a dry-weight basis and removed it from the Controlled Substances Act. Oversight of hemp cultivation moved to the U.S. Department of Agriculture.

That change created the modern CBD market. It did not hand the entire category to retailers, though: the 2018 Farm Bill explicitly preserved the FDA’s authority over hemp products, which is why food and supplement rules still apply.

Hemp-Derived CBD vs. Marijuana-Derived CBD: Why the Source Matters

CBD is the same molecule whether it comes from hemp or marijuana, but the law treats the two sources very differently. Legality follows the plant, not the compound.

Hemp and marijuana are both cannabis; the legal difference is THC content. CBD pulled from hemp (no more than 0.3% THC) is federally legal, while CBD pulled from higher-THC marijuana is a controlled substance outside of state cannabis programs. For a fuller breakdown of the compound and how products differ, see our guide to what CBD is.

Product labels add another wrinkle. CBD isolate contains only CBD; broad-spectrum products include other cannabinoids but little or no THC; and full-spectrum products keep the plant’s natural profile, including trace THC. That trace THC is legal today, but it is exactly what the 2026 rules target.

The 2025 Federal Hemp Law That Changes CBD in November 2026

The biggest change on the horizon is a rewrite of the federal definition of hemp itself. Tucked into the spending law that ended the government shutdown in November 2025, the new language takes effect on November 12, 2026, and it will push many products that are legal today back outside the definition of hemp.

According to a Congressional Research Service analysis, the new definition makes three key changes. It measures “total THC” (including THCA) rather than delta-9 THC alone, keeping the 0.3% dry-weight ceiling but counting more compounds toward it. It caps finished consumer products at 0.4 milligrams of total THC per container. And it excludes cannabinoids that are synthesized or manufactured outside the plant. Any hemp-derived product that exceeds those limits will be regulated as marijuana under the Controlled Substances Act once the change takes effect.

That per-container cap is low enough to sweep in products well beyond delta-8 gummies. The White House has acknowledged that some full-spectrum CBD products “will once again be controlled as marijuana” because they carry THC above the new threshold, and the industry group the U.S. Hemp Roundtable estimates that more than 90% of non-intoxicating CBD products on the market today exceed the per-container limit. The law gives companies a one-year runway to reformulate and directs the FDA to publish lists of which cannabinoids count toward the cap. Lawmakers have already filed bills to delay or repeal the change, and the fight over those November hemp restrictions is ongoing.

Delta-8, THCA, and the “Farm Bill Loophole”

Intoxicating cannabinoids like delta-8 THC and THCA have spread by exploiting a gap in the 2018 Farm Bill, and they are the clearest target of the 2026 rules. Because the old definition capped only delta-9 THC, products rich in other THC compounds could be sold as “hemp.”

Delta-8 THC occurs only in tiny amounts in the plant, so the FDA notes that most delta-8 on the market is manufactured by chemically converting hemp-derived CBD. The agency warns that these products are intoxicating, have not been evaluated for safety, and have been linked to adverse-event and poison-control reports, including cases involving children. THCA flower raises a similar issue, because it converts to intoxicating delta-9 THC when heated.

Many states did not wait for Washington. A number have already banned or tightly restricted delta-8 and similar cannabinoids, and the trend is accelerating; Tennessee, for example, moved to ban THCA under new hemp rules. Once the federal definition changes, these converted and high-THC products lose their hemp status nationwide.

The FDA’s Position on CBD in Food, Drinks, and Supplements

The FDA’s stance is blunt: CBD cannot legally be sold as a dietary supplement or added to food and beverages, regardless of whether it comes from hemp. That position is separate from the Farm Bill and did not change when hemp was legalized.

In January 2023, the agency concluded that its existing food and supplement frameworks are not appropriate for CBD, denied petitions asking it to allow CBD in supplements, and said a new regulatory pathway from Congress is needed. The FDA cited safety questions around long-term use, including potential harm to the liver, interactions with other medications, and possible effects on the male reproductive system.

The one place CBD has cleared the FDA is as a prescription drug. The agency approved Epidiolex, a purified CBD medicine for rare and severe seizure disorders, in 2018, and that approval is the legal reason CBD cannot also be sold as a supplement. The FDA continues to send warning letters to companies making unproven health claims, and its own testing has found products that contain more or less CBD than their labels state. For older consumers weighing these products, our explainer on FDA and Medicare CBD policy goes deeper.

Where Marijuana and Marijuana-Derived CBD Are Legal by State

Hemp-derived CBD is legal in nearly every state, but marijuana-derived CBD is legal only where marijuana itself is. That distinction is what older state-by-state “CBD maps” often get wrong.

By the White House’s count, 40 states plus the District of Columbia run regulated medical-marijuana programs, and 24 states plus D.C. have legalized adult (recreational) use. In those states, marijuana-derived CBD is available through licensed dispensaries. Everywhere else, only hemp-derived CBD is an option, and even then some states restrict intoxicating hemp cannabinoids more tightly than the federal floor.

Federal marijuana policy is shifting too. In a final order effective April 28, 2026, the Justice Department moved FDA-approved marijuana medicines and state-licensed medical marijuana from Schedule I to the less-restrictive Schedule III. Recreational marijuana and synthetically derived THC stayed in Schedule I. That rescheduling does not change anything for hemp-derived CBD, which was already outside the Controlled Substances Act, but it eases federal treatment of state medical-marijuana products, including marijuana-derived CBD sold in those programs.

Can You Travel With CBD?

You can fly within the United States with hemp-derived CBD. The Transportation Security Administration allows CBD products that contain no more than 0.3% THC, or that are FDA-approved, in both carry-on and checked bags; marijuana and most other CBD products remain prohibited.

TSA explains that its officers are not searching for drugs, but they will refer anything that appears to be an illegal substance to law enforcement. To avoid friction, keep CBD in its original labeled packaging, carry a certificate of analysis if you have one, and follow the 3.4-ounce liquids limit for oils and tinctures in carry-on bags. Two more cautions apply: state laws vary, so a product that is fine at your departure airport may not be welcome at your destination, and you should not carry any CBD or THC product across international borders, where penalties can be severe.

What’s Next for CBD Law

The defining question for CBD is whether Congress changes course before the new hemp definition takes effect on November 12, 2026. If it does not, many full-spectrum and intoxicating hemp products will lose their legal status that day.

Several bills would delay or repeal the change, and the December 2025 executive order on cannabis research directs federal officials to work with Congress to preserve access to “appropriate full-spectrum CBD products” while keeping the most intoxicating items off the shelf. The FDA, meanwhile, has yet to publish the cannabinoid lists the new law requires. Until the picture settles, the safest approach is the one that has always served CBD shoppers well: confirm your state’s rules, buy lab-tested products that document their THC content, and watch the November 2026 deadline.
