What is CBD?
Cannabidiol (CBD): What It Is, How It Is Used, and Why It Is Regulated
Cannabidiol (CBD) is a naturally occurring compound, known as a cannabinoid, that is found in the Cannabis sativa (cannabis) plant. Unlike tetrahydrocannabinol (THC), the main psychoactive component of cannabis, CBD does not produce a “high” or intoxicating effect. This means that it does not significantly alter a person’s mental state or perception.
CBD has become increasingly popular in recent years because many consumers believe it may help support their wellbeing. People commonly use CBD products for reasons such as:
- Managing pain and discomfort
- Reducing anxiety and stress
- Improving sleep and helping with insomnia
- Supporting relaxation and general wellbeing
However, research into the effectiveness of CBD for many of these uses is still ongoing, and claims about health benefits must be supported by scientific evidence.
CBD Products in the UK
In the United Kingdom, CBD products are widely available and are often sold as foods or food supplements. They can be purchased from:
- Health food stores
- Pharmacies
- Supermarkets
- Cafés
- Online retailers
CBD food products are available in many forms, including:
- CBD oils
- Drops, tinctures, and oral sprays
- Gel capsules and soft gels
- Sweets, gummies, and confectionery
- Bread and bakery products
- Tea, coffee, and other beverages
- Protein bars and other snack products
The amount of CBD varies between products, so consumers should carefully read product labels and follow the manufacturers recommendations.
Why CBD Food Products Are Regulated
CBD food products are classified as novel foods in the UK. A novel food is a food that was not widely consumed before May 1997 and therefore requires a safety assessment before being sold.
Before a CBD food product can be legally marketed, it must undergo a review process to demonstrate that it is:
- Safe for consumers
- Correctly labelled
- Produced to appropriate quality standards
- Suitable for its intended use
This authorisation process helps protect consumers and ensures that CBD products meet UK food safety requirements.
Physical and Chemical Properties of CBD
From a scientific perspective, pure CBD is a colourless crystalline solid at room temperature. It has a defined chemical structure and can undergo chemical changes when exposed to certain conditions.
For example:
- In strongly alkaline (basic) environments and in the presence of oxygen from the air, CBD can be oxidised.
- During this process, CBD may be converted into other compounds, including cannabinodiol (CBND) and a quinone compound known as HU-331.
These chemical transformations are mainly of interest to scientists and manufacturers studying the stability and behaviour of CBD during production, storage, and laboratory testing.

Summary
CBD is a non-psychoactive compound derived from the cannabis plant that is widely used in food supplements and wellness products. It is available in many forms, including oils, capsules, sweets, and drinks. Because CBD food products are considered novel foods in the UK, they must undergo safety assessment and authorisation before they can be legally sold. Scientifically, CBD is a colourless crystalline substance that can transform into other compounds under specific chemical conditions.
