Everything You Need To Know About Medical Cannabinoids In The UK

In recent years, the conversation around medical cannabinoids in the UK has evolved significantly. With growing research supporting their potential benefits, patients curious about medicinal cannabis now have more information and access than ever before. This guide aims to provide an overview of medical cannabinoids, their legal status, potential uses, and what patients in the UK need to know.

What Are Medical Cannabinoids in the UK?

Medical cannabinoids are active compounds extracted from the cannabis plant, which have been the focus of increasing medical interest and research. The two most prominent cannabinoids are Cannabidiol (CBD) and Tetrahydrocannabinol (THC).

Cannabidiol (CBD): CBD is a non-psychoactive compound, meaning it does not produce the ‘high’ commonly associated with cannabis use. This characteristic makes it an appealing option for patients seeking potential therapeutic benefits without the mind-altering effects. CBD has been studied for its role in relieving symptoms associated with various conditions such as anxiety, depression, and chronic pain. It is also the primary active ingredient in Epidiolex, the first cannabis-derived medication approved by regulatory authorities for the treatment of certain types of epilepsy.

Tetrahydrocannabinol (THC): THC is the main psychoactive component of the cannabis plant. It is responsible for the ‘high’ sensation but also has medicinal properties. THC can help alleviate pain, nausea, and muscle spasticity and stimulate appetite, which can be beneficial for patients undergoing treatments like chemotherapy. However, due to its psychoactive effects, the medical use of THC is more regulated and is typically considered in cases where other treatments have failed.

Other Cannabinoids: Besides CBD and THC, the cannabis plant contains over 100 other cannabinoids, such as Cannabinol (CBN) and Cannabigerol (CBG), each potentially offering unique therapeutic benefits. Researchers continue to explore these compounds, seeking to understand their individual and combined effects on various medical conditions.

The Entourage Effect: This term refers to the theory that cannabinoids can work better when used together, as they naturally occur in the cannabis plant, rather than when used individually. The idea is that the combination of cannabinoids, along with other compounds found in the plant like terpenes, can enhance the therapeutic effects and mitigate side effects.

How Cannabinoids Work: Cannabinoids interact with the body’s endocannabinoid system (ECS), a complex cell-signalling system involved in regulating a range of functions, including pain, mood, appetite, and sleep. The ECS has two primary receptors, CB1 and CB2. THC binds to these receptors, especially CB1 receptors in the brain, resulting in the psychoactive effects. CBD, on the other hand, does not bind directly to these receptors but influences them indirectly and also interacts with other receptors in the body, contributing to its therapeutic effects.

In conclusion, medical cannabinoids represent a diverse and promising field in medicine, offering potential relief for a variety of conditions. Their complexity and varying effects underscore the importance of careful study and clinical trials to fully understand and harness their therapeutic potential.

This includes conditions like neuropathic pain, where traditional pain relief methods may not be effective. Patients suffering from chronic pain conditions such as arthritis or fibromyalgia may find relief with cannabinoid therapies.

Severe Forms of Epilepsy: The UK has recognized the benefits of cannabinoids, particularly CBD, in managing severe and rare forms of epilepsy. This includes conditions like Dravet syndrome and Lennox-Gastaut syndrome, where CBD has been effective in reducing the frequency and severity of seizures. Epidiolex, a CBD-based medication, is one such example used for treatment.

Multiple Sclerosis (MS): For MS patients, cannabinoids have been found to alleviate symptoms such as muscle stiffness and spasms. In the UK, Sativex, a cannabis-derived oral spray containing a combination of THC and CBD, is one of the treatments prescribed for managing these symptoms in MS patients.

Nausea and Vomiting Due to Chemotherapy: THC is recognised for its effectiveness in reducing nausea and vomiting associated with chemotherapy. This can also help in improving the appetite of cancer patients undergoing such treatments, addressing issues of weight loss and malnutrition.
