Updated 25 June 2026 / CBD legality
How old do you have to be to buy CBD in the UK?
The practical answer is simple: buy CBD as an adult, from an age-aware retailer, and treat under-18 use as a medical-supervision question. The legal detail is more nuanced, because CBD oils, gummies, capsules, topicals and vapes do not all sit in the same retail bucket.
Start here
There is no single CBD age rule for every format, but 18+ is the responsible buying line.
For standard CBD foods and supplements, UK law does not set one simple CBD-specific age-of-sale rule that covers every oil, gummy, capsule or topical product. That does not mean CBD should be sold casually to children.
Responsible retailers commonly restrict CBD sales to adults aged 18 and over. The Food Standards Agency CBD guidance also treats under-18s as a vulnerable group for CBD consumption and encourages labels that say CBD is not suitable for people under 18.
Why shops ask
Age checks are about suitability, not just intoxication.
CBD is not sold as a recreational high. The adult-only retail approach is about something more practical: product labels, serving sizes, medicine cautions, lab reports and the ability to make an informed choice.
Online retailers may ask for age confirmation at checkout, and stronger age verification is normal when the format is vape-related. If a CBD retailer does not make age, suitability or lab-report information easy to check, that is a reason to slow down.
- Checkout
- Expect an 18+ policy from a responsible CBD shop.
- Label
- Check CBD amount per serving and vulnerable-group warnings.
- Proof
- Look for batch or lab-report evidence before buying.
Different decisions
Adults can shop; under-18 use needs a much higher bar.
Adults 18+
Can usually buy compliant CBD products from a reputable retailer, while staying within current food-safety advice, checking the label and asking for professional advice if medicines or health conditions are involved.
Under 18
Should not be treated as normal wellness users. FSA guidance says vulnerable groups, including children, should avoid CBD unless under medical direction.
That distinction matters. A missing age-of-sale clause for one CBD format is not the same thing as a green light for teenagers to self-select CBD.
CBD vape products
CBD vapes are a separate age-check conversation.
CBD vape products should not be treated like a bottle of CBD oil or a packet of capsules. GOV.UK vape retail guidance requires suitable age-verification policies for vaping products, and nicotine-containing vaping products are age restricted for under-18s.
The direction of travel is clear: youth access to vaping products is being tightened, and responsible sellers should not place vape-related products in front of underage buyers.
How to buy CBD safely
Age is only one check. Product proof is the other.
Compliant CBD buying is not just about being old enough. A sensible buyer also checks whether the product is traceable, clearly labelled, supported by testing and sold without disease-treatment promises.
For CBD foods, the FSA currently advises a 10mg daily CBD limit for healthy adults and encourages labels to make serving size, under-18 suitability and medication cautions clear. The Home Office CBD factsheet also explains why controlled-cannabinoid evidence matters for finished CBD products.
- Serving
- CBD amount per serving is clear before checkout.
- Testing
- Batch or lab-report route is easy to find.
- Claims
- No promise to treat, cure or prevent disease.
Simple buying route
Use the adult buyer checklist before you choose a format.
If you are 18 or over, the format question comes after the suitability check. Oils, gummies, capsules, patches, topicals and vapes all create different routines, but each should start with a transparent label and a retailer you trust.
For most first-time adult buyers, the safer route is not the strongest product. It is the clearest product: one with obvious serving information, batch evidence, published testing and practical support if you have a question.
Questions customers ask
CBD age questions are really suitability questions.
The safest answer is not just a number. It is a route: adult purchase, responsible retailer, clear product evidence and medical advice where the person is under 18 or in another vulnerable group.
Can you buy CBD under 18 in the UK?
For standard CBD foods and supplements, there is not one simple CBD-specific age-of-sale rule for every format. In practice, responsible retailers commonly use an 18+ policy, and FSA guidance treats under-18s as a vulnerable group for CBD consumption.
Can an 18 year old buy CBD?
Usually, yes, an adult aged 18 or over can buy compliant CBD products from a responsible UK retailer. They should still check serving size, lab evidence, suitability warnings and current CBD food-safety advice.
Is CBD suitable for teenagers?
CBD should not be treated as a normal wellness product for teenagers. The FSA says vulnerable groups, including children, should avoid CBD unless under medical direction.
Are CBD vapes age restricted?
Vaping products are treated differently from CBD oils, gummies and capsules. UK retailer guidance requires suitable age-verification policies for vaping products and says retailers should not sell to under-18s.
Do you need ID to buy CBD online?
Many responsible retailers use age checks at checkout or delivery, especially for vape products. Even where a standard CBD format is not subject to a specific age-of-sale rule, an 18+ policy is a sensible responsible-retail standard.
Final answer
Buy CBD as an adult, and choose proof over guesswork.
Reviewed 25 June 2026. If you are 18 or over, buy CBD from a transparent UK retailer that makes age policy, label information, serving size and testing easy to check. If the person is under 18, pregnant or breastfeeding, trying to conceive, immunosuppressed or taking medication, the right next step is professional medical advice, not casual checkout.
