Is CBD Legal? The Three UK Rules a Product Has to Clear
Is CBD legal in the UK? Pure CBD is not a controlled drug, but a product must also clear the 1mg exempt-product test, the FSA food rules and the MHRA line.
By Staff, CBD Wire
Is CBD legal? In the UK, pure CBD as an isolated substance is not a controlled drug, per the Home Office. A CBD product has to clear three separate rules: drugs law (any THC must sit inside the exempt-product definition), food law (CBD foods are novel foods needing authorisation) and medicines law (a medical claim makes it a medicine).
This is an evergreen explainer, not a news story. This desk read the Home Office drug licensing factsheet, the Food Standards Agency’s CBD page and the MHRA’s current CBD statement on gov.uk on 13 November 2026, and built the table below from those three documents.
Is CBD legal in the UK? The three rules in one table
Each row is a rule as the named document states it, with the date the document carried when this desk read it.
| Rule | What it means for a buyer | Document, as read 13 November 2026 | Scope |
|---|---|---|---|
| Pure CBD is not controlled | An isolate on its own is not a controlled drug | Home Office factsheet, para 5, updated 3 October 2024 | Drugs law |
| Products with controlled cannabinoids are Class B | THC and cannabinol derivatives are Class B; the Home Office says consumer products contain them | Home Office factsheet, paras 4 to 6 | Drugs law |
| Exempt product: all three limbs met | Under 1mg per component part is one limb, not the whole test | Home Office factsheet, paras 26 to 29; Regulation 2, MDR 2001 | Drugs law |
| CBD foods must be authorised | Oils, drinks and gummies sold as food are novel foods | FSA CBD page, published 13 February 2020 | England, Northern Ireland, Wales |
| The FSA list is not authorisation | Off-list products “should not be on the market” | FSA CBD page, section 1 | England and Wales, as worded |
| 10mg a day from food | About 4 to 5 drops of 5% oil, for healthy adults | FSA CBD page, advice issued October 2023 | England, Northern Ireland, Wales |
| A medical claim makes it a medicine | Needs a Marketing Authorisation to be sold, supplied or advertised, unless exempt | MHRA statement, published 14 April 2025 | UK |
| The 2016 MHRA statement is gone | Pages citing it are citing a withdrawn text | MHRA news article of 13 October 2016, withdrawn 14 April 2025 | Historical |
No single page among the three puts these rules side by side. The Home Office factsheet says so itself: its paragraph 2 states that it does not give guidance on non-drugs regimes such as medicines or foods.
Rule one: drugs law and the exempt product
The Home Office drug licensing factsheet starts from the molecule. Paragraph 5 says pure CBD is not controlled under the Misuse of Drugs Act 1971, then adds the catch in the next breath: the legal status of a CBD product depends on what the product is.
The reason is extraction. The Home Office agrees with the Advisory Council on the Misuse of Drugs that, because CBD is hard to isolate from other cannabinoids, consumer CBD products also contain varying amounts of controlled ones such as THC. Paragraph 6 says any CBD product containing controlled cannabinoids is a Class B drug, unless it meets the “exempt product” definition in Regulation 2 of the Misuse of Drugs Regulations 2001.
Is CBD a controlled substance in the UK?
The substance, no. Most products, potentially yes, until the exempt-product test is applied. That test has three limbs, set out in paragraph 27:
- the product is not designed for administration of the controlled drug to a human being or animal;
- the controlled drug cannot be recovered by readily applicable means;
- no one component part of the product contains more than one milligram of the controlled drug.
Paragraph 28 says all three limbs must be met. Paragraph 29 says whether a product meets the definition is a matter of fact, decided case by case.
Where the 1mg figure fits
The 1mg is the third limb, measured per component part, not a percentage of the oil. A product under 1mg of THC is not automatically lawful if it fails either of the other two limbs. This site’s 1mg rule explainer works through the arithmetic. The 0.2% THC figure that some shops quote does not appear in the text this desk read for this post; where it comes from is covered in our CBD flower explainer.
Rule two: food law and the FSA public list
Clearing drugs law does not put a CBD food on the shelf lawfully. The Food Standards Agency’s CBD page, which applies to England, Northern Ireland and Wales, says CBD food products, as novel foods, must be authorised before they are put on the market.
The FSA’s public list is where buyers usually look, and it is easy to misread. Per the regulator, products on the list are not formally authorised for sale and have not yet been fully assessed for safety; they are linked to applications moving through the novel foods process, and inclusion is no guarantee of authorisation. The same section says products not on the list should not be on the market in England and Wales.
The page also carries the precautionary intake advice issued in October 2023: healthy adults should limit CBD from food to 10mg a day, which the FSA puts at about 4 to 5 drops of 5% CBD oil. It advises those trying to conceive, pregnant or breastfeeding separately. Scotland’s food regime is run by Food Standards Scotland, whose guidance this desk did not read, so nothing in this section is stated for Scotland.
How the list has changed over time is in our note on the FSA’s updated guidance.
Rule three: medicines law and the MHRA
The third rule turns on what the seller says. The MHRA statement on products containing CBD, published 14 April 2025, says CBD products used for medical purposes are medicines. A company that markets a CBD product with a medicinal claim will be considered to fall within the definition of a medicinal product in the Human Medicines Regulations 2012, and medicinal products must hold a Marketing Authorisation for legal sale, supply or advertisement in the UK, unless exempt.
The MHRA adds that it can give no assurance a product will not later be classified as a medicine. It also points readers back to the FSA on food status, saying the FSA confirmed CBD’s novel-food status in January 2019.
The 2016 MHRA statement, which many older pages still quote, carries a notice on gov.uk that it was withdrawn on 14 April 2025 because the new statement had been published. Quote the 2025 text, not the 2016 one.
For a buyer the practical reading is simple: a CBD food that promises to treat a condition is making a claim the MHRA treats as medicinal. That is a reason to put it down, not a reason to pay more.
What this means at the shelf
Put the three rules in order and the checks write themselves. First, a batch lab report that shows controlled cannabinoids per component part, read against the 1mg limb. Second, the product’s name on the FSA public list, for food sold in England and Wales. Third, the label and the website, for any claim to treat, cure or prevent.

Frequently asked questions
Is CBD legal in the UK?
Pure CBD, as an isolated substance, is not controlled under the Misuse of Drugs Act 1971, per the Home Office. A CBD product is a different question: if it contains controlled cannabinoids such as THC it is Class B unless it meets all three limbs of the exempt-product definition. Sold as food, it is also a novel food, and sold with a medical claim, it is a medicine.
Is CBD a controlled substance in the UK?
Not on its own. The Home Office factsheet says pure CBD is not controlled under the 1971 Act, but that consumer CBD products also contain varying amounts of controlled cannabinoids, a view it shares with the Advisory Council on the Misuse of Drugs. Those products are Class B unless they meet the exempt-product definition in Regulation 2 of the Misuse of Drugs Regulations 2001.
How much THC is legal in CBD UK?
The exempt-product definition sets no THC percentage that makes a product lawful. The exempt-product definition says no one component part may contain more than one milligram of a controlled drug, and that is one limb of three; the product must also not be designed to deliver the drug, and the drug must not be readily recoverable. The Home Office says it is a matter of fact, determined case by case.
Can you get in trouble for CBD in the UK?
The Home Office factsheet says a product meeting the exempt-product definition is not subject to the 1971 Act’s prohibitions on supply and possession. A CBD product that contains controlled cannabinoids and does not meet it is a Class B drug under that Act. This desk did not read sentencing guidance and states no penalty; the factsheet is not legal advice, and neither is this.
The Home Office calls its factsheet general guidance, not legal advice, and CBD Wire takes no view on whether any particular product meets the exempt-product definition. Check the product against the FSA’s public list before you check the price. For adults.
