Hemp oil is legal under federal law when it comes from hemp plants containing no more than 0.3 percent delta-9 THC on a dry-weight basis, a threshold set by the 2018 Farm Bill.1Brookings Institution. The Farm Bill, Hemp, and CBD: Explainer That answer covers plain hemp seed oil cleanly. It gets more complicated for CBD oil, which the FDA still says cannot legally be sold as a food or dietary supplement, and it is about to change substantially: a law Congress passed in November 2025 will redefine hemp starting November 12, 2026, and pull many currently legal CBD products back under the Controlled Substances Act.2Congressional Research Service. Hemp, CBD, and the Controlled Substances Act State law adds a second layer on top of all of this.
Hemp Seed Oil and CBD Oil Are Not the Same Product
The label “hemp oil” gets used for two very different things, and the legal treatment splits along that line.
Hemp seed oil is pressed from the seeds of the cannabis plant. It contains no CBD and essentially no THC. The FDA has evaluated hulled hemp seed, hemp seed protein powder, and hemp seed oil as Generally Recognized as Safe for use in human food, and these are the only hemp-derived ingredients currently permitted in food under federal law.3FDA. FDA Regulation of Cannabis and Cannabis-Derived Products, Including Cannabidiol (CBD) If a bottle labeled “hemp oil” contains only hemp seed oil, it is legal to buy, sell, possess, and consume.
CBD oil is different. It is extracted from the stalks, leaves, and flowers of the hemp plant and contains varying amounts of cannabidiol along with other cannabinoids. The industry markets it as full-spectrum, broad-spectrum, or isolate, but those terms are not standardized by any federal regulator. Labels are frequently inaccurate. Research published in the Journal of the American Medical Association found that 43 percent of tested CBD oils contained higher levels of THC than their labels indicated.4SHRM. Cannabis Oil Complicates Drug Testing
Where the FDA Draws the Line on CBD
Hemp itself is no longer a controlled substance, but the FDA’s authority over what you put in food, supplements, and drugs did not go away with the Farm Bill. The agency’s position is that adding CBD to food or marketing it as a dietary supplement violates the Federal Food, Drug, and Cosmetic Act. The legal reason is the “prior drug exclusion”: CBD is the active ingredient in the FDA-approved epilepsy drug Epidiolex and was the subject of substantial clinical investigation before anyone tried to sell it as a supplement, which under the statute blocks it from being treated as a food additive or dietary ingredient.3FDA. FDA Regulation of Cannabis and Cannabis-Derived Products, Including Cannabidiol (CBD)
In January 2023, the FDA formalized this position, concluding that existing regulatory frameworks for foods and dietary supplements are “not appropriate” for CBD and declining to open rulemaking. The agency cited potential liver harm, drug interactions, reproductive risks, and inadequate safety data, saying it had “not found adequate evidence to determine how much CBD can be consumed, and for how long, before causing harm.”5FDA. FDA Concludes That Existing Regulatory Frameworks for Foods and Supplements Are Not Appropriate for Cannabidiol It called on Congress to build a new pathway. Congress has not.
What that means in practice: the FDA continues to send warning letters to companies that add CBD to food and beverages, and especially to companies that market CBD with therapeutic claims such as curing cancer or treating depression.3FDA. FDA Regulation of Cannabis and Cannabis-Derived Products, Including Cannabidiol (CBD) The FTC’s truth-in-advertising rules back this up: it is illegal to claim a hemp or CBD product can prevent, treat, or cure a disease without adequate scientific evidence.6LegitScript. CBD Product Labeling Regulations Enforcement against retail sellers of unadulterated CBD oil has been limited, which is why the products remain widely available, but their federal status as food or supplements is not settled law in their favor. It is enforcement discretion.
What Changes on November 12, 2026
On November 12, 2025, Congress enacted H.R. 5371, a continuing resolution that included Section 781. That section rewrites the federal definition of hemp, and it takes effect one year after enactment.2Congressional Research Service. Hemp, CBD, and the Controlled Substances Act The changes are substantial:
- The legal threshold shifts from delta-9 THC alone to total THC, including delta-9 THC, THCA, and other cannabinoids with similar effects.
- Final products intended for human or animal ingestion, inhalation, or topical use may contain no more than 0.4 milligrams of total THC per container. This is low enough to eliminate most full-spectrum CBD products from the legal market.
- Intermediate hemp-derived products must contain no more than 0.3 percent total THC on a dry-weight basis after decarboxylation.
- Any cannabinoid not naturally produced by the cannabis plant, or one that is naturally produced but was synthesized outside the plant, falls outside the definition of hemp and is treated as a Schedule I controlled substance.2Congressional Research Service. Hemp, CBD, and the Controlled Substances Act
A December 18, 2025, Executive Order from President Trump acknowledged the effect directly, stating that “some full-spectrum CBD products will once again be controlled as marijuana under the CSA,” and directed officials to work with Congress on a revised definition.7The White House. Increasing Medical Marijuana and Cannabidiol Research Representative Nancy Mace introduced H.R. 6209 in November 2025 to repeal Section 781, and Representative Jim Baird introduced legislation to delay the total THC ban by two years.8Roll Call. House Farm Bill Would Set Hemp Testing, Pesticide, Label Authority As of mid-2026, neither has passed. The FDA was required to publish, within 90 days, lists identifying the cannabinoids covered by the new definition; it missed the February 2026 deadline without explanation.9Marijuana Moment. FDA Misses Deadline to Publish Cannabinoid List and Define Hemp Containers
Until November 12, 2026, the 2018 Farm Bill’s delta-9-only, dry-weight standard still governs at the federal level. After that date, unless Congress intervenes, a hemp oil product legal today can become a controlled substance without changing formulation.
Delta-8 THC and Other Intoxicating Cannabinoids
The most contested corner of the hemp market has been intoxicating cannabinoids like delta-8 THC, typically produced by chemically converting CBD extracted from legal hemp. Because the 2018 Farm Bill defined hemp using only delta-9 THC, products high in delta-8 could qualify as hemp so long as delta-9 stayed under 0.3 percent.
The DEA pushed back. Its August 2020 Interim Final Rule stated that “all synthetically derived tetrahydrocannabinols remain schedule I controlled substances,” and a September 2021 letter to the Alabama Board of Pharmacy called delta-8 a “synthetic THC” outside the Farm Bill’s protection.10Federal Register. Implementation of the Agriculture Improvement Act of 2018 The Ninth Circuit went the other way in 2022. In AK Futures LLC v. Boyd St. Distro, LLC, it held that the “plain and unambiguous” text of the Farm Bill covers delta-8 products containing no more than 0.3 percent delta-9 THC.11Wilson Elser. Ninth Circuit Rules Hemp-Derived Delta-8 THC Products Are Federally Legal
The November 2025 law resolves the federal side of this by excluding synthetic cannabinoids and imposing the total THC cap. The state side remains a patchwork. As of mid-2026, thirteen states — Colorado, New York, Idaho, and Vermont among them — fully prohibit intoxicating hemp-derived cannabinoids, while others cap potency, restrict sales locations, or set a minimum purchase age.12Marijuana Policy Project. What Are State Regulators Doing About Delta-8
States Can Go Further Than Federal Law
Federal legality is a floor, not a guarantee. States can add restrictions on hemp-derived products, and the results vary widely.
Some states have built regulatory systems around hemp-derived cannabinoids with licensing, lab testing, age restrictions, and potency caps. Louisiana enacted one of the more detailed frameworks through 2019 and 2022 legislation. Michigan requires that delta-8 products be manufactured and distributed only by state-licensed companies and sold to buyers 21 or older. Other states broadly prohibit hemp-derived intoxicants or push them into the medical or adult-use cannabis system. Texas allows delta-8 sales under a temporary court injunction that blocked the state from classifying it as a controlled substance.12Marijuana Policy Project. What Are State Regulators Doing About Delta-8
There are no comprehensive federal labeling or testing standards for hemp-derived CBD products. A 2020 survey of 31 states with cannabis programs found that all required THC content disclosure and manufacturer contact information, about half required potency verification from a testing laboratory, and just over a third required mold testing results.13National Library of Medicine. Cannabis Product Labeling Requirements For consumers, a third-party certificate of analysis is often the only reliable check on what a bottle actually contains.
Drug Testing: Legal to Buy, Still a Problem at Work
Buying and using a legal hemp oil product does not protect you from a positive workplace drug test. Standard panels look for THC metabolites, not CBD, and because CBD products commonly contain more THC than the label indicates, use can produce a positive result.
For safety-sensitive workers covered by U.S. Department of Transportation rules, including truck drivers, pilots, train engineers, and transit operators, DOT policy is explicit: CBD use is not accepted as a “legitimate medical explanation” for a positive marijuana test, and a medical review officer will verify the test as positive regardless of the employee’s claim.14U.S. Department of Transportation. CBD Notice
The Americans with Disabilities Act does not require employers to accommodate CBD use, because the ADA’s definition of illegal drugs is tied to the Controlled Substances Act, and any product above 0.3 percent THC remains Schedule I. Even in states that protect the use of lawful products outside work, courts have put the burden on the employee to prove the CBD product they used was actually legal, which is difficult given the state of product labeling.15UNC School of Government.

Flying and Crossing Borders With Hemp Oil
The TSA permits hemp-derived products containing no more than 0.3 percent THC through airport screening, consistent with the 2018 Farm Bill.16TSA. Medical Marijuana TSA officers are not searching for drugs, but if they find something they believe is illegal, they must refer it to law enforcement, and they may not be able to distinguish a legal hemp product from a cannabis product by sight. The individual officer makes the call at the checkpoint.
International travel is riskier. Canada regulates CBD under its Cannabis Act, restricts sales to authorized retailers, and requires Health Canada permits to import it.17Health Canada. Cannabidiol The European Union classifies CBD as a “novel food,” and no CBD product has received full authorization for oral consumption, though the European Food Safety Authority has more than 200 applications under review.18EFSA.
