CBD (cannabidiol) is a naturally occurring compound found in hemp that does not produce the intoxicating effects associated with THC. Many people use CBD products as part of a general wellness routine*, with options ranging from oils and capsules to gummies and topicals.
This guide breaks down what CBD actually is, how it's regulated in the UK, the different forms it comes in, and what to know before trying it.
What Is CBD?
CBD is one of more than 100 natural compounds found in the hemp plant. Unlike THC, CBD does not cause a "high"; it's non-intoxicating and won't impair the way you think or feel. Manufacturers typically extract CBD from hemp plants that are naturally low in THC, then formulate it into oils, capsules, edibles, and skincare.
Inside the body, CBD is understood to interact with the endocannabinoid system (ECS), a network of receptors involved in regulating everyday functions such as sleep, mood, and recovery after exercise.* Researchers are still working to understand exactly how CBD engages with the ECS, and much of the underlying science is still developing. Those who want a closer look at the ECS can explore our guide on How Does CBD Oil Work? Understanding the Endocannabinoid System.
CBD Oil, Isolate, and Broad or Full Spectrum: What's the Difference?
CBD oil is CBD extract combined with a carrier oil, such as MCT or hemp seed oil, typically taken under the tongue. If you're interested in learning more about how CBD oils are made, used, and labelled, our What Is CBD Oil? A Complete Guide for UK Users covers the basics in greater detail. CBD isolate is pure, crystalline CBD with all other plant compounds removed, containing no detectable THC.
Broad-spectrum CBD includes other naturally occurring hemp compounds, like terpenes and additional cannabinoids, but has THC removed. Full-spectrum CBD retains the fullest range of naturally occurring compounds, including trace, legally compliant levels of THC.
Is CBD Legal in the UK?
Yes. CBD itself is not a controlled substance in the UK under the Misuse of Drugs Act 1971. However, finished products must contain no more than 1mg of controlled cannabinoids, including THC, per container to stay within the law, and cannot be marketed for any psychoactive purpose.
Ingestible CBD products, including oils, capsules, drinks, and gummies, also fall under the Food Standards Agency's (FSA) Novel Food framework. The FSA maintains a Public List of products linked to novel food applications and has published a provisional Acceptable Daily Intake of 10mg of CBD per day for healthy adults, with specific groups advised against consuming CBD. The FSA continues to assess novel food applications, so the regulatory picture may continue to evolve.
Common Forms of CBD
- CBD oil drops: taken under the tongue; one of the most popular and precise ways to use CBD.
- CBD capsules: pre-measured, convenient, and free from the earthy taste of oil.
- CBD gummies: a flavoured, easy-to-dose edible format.
- CBD topicals: balms and lotions applied directly to the skin.
- CBD vape products: inhaled forms that some people use for faster absorption.
-
CBD drinks: ready-to-drink beverages infused with CBD, growing in popularity as an alternative to oils and capsules.
Wellness Benefits of CBD
Many people choose CBD as part of a general wellbeing routine rather than as a medical treatment. Commonly reported uses include:
- Helping support management of everyday stresses*
- Helping support a sense of calm and relaxation*
- Supporting healthy sleep cycles*
- Supporting recovery after exercise*
Potential Side Effects of CBD
CBD is generally well tolerated, but as with any supplement, some people experience mild side effects, particularly at higher doses. These can include:
- Dry mouth
- Drowsiness or fatigue
- Changes in appetite
- Digestive upset, such as diarrhoea
Medication interactions: CBD may interact with certain prescribed medicines, particularly those metabolised by the liver. Anyone taking prescription medication, who is pregnant or breastfeeding, or who is managing an existing health condition should speak to a doctor or pharmacist before starting CBD.
How to Choose a Quality CBD Product
Not all CBD products are equal. Look for:
- Third-party lab testing and a Certificate of Analysis confirming cannabinoid content and THC compliance.
- Clear labelling: accurate CBD milligram content per serving.
- Traceable sourcing: hemp grown organically, non-GMO, and pesticide-free.
- Transparent brand practices: companies that publish batch-specific lab results rather than generic ones.
