CBD vs Medical Cannabis Overview
While both CBD and medical cannabis come from the same plant, their legal status, usage, and accessibility in the UK differ dramatically. Understanding these differences can help you make informed choices for your wellness or medical needs.
| Aspect | CBD | Medical Cannabis |
|---|---|---|
| Legal Status (UK) | Legal as a food supplement if <0.2% THC | Available by prescription from a specialist |
| THC Content | Low to none (broad-spectrum or isolate) | May contain higher THC levels |
| Where to Buy | Online, high street shops | NHS (rare) or private clinics |
| Purpose | Wellness support (stress, sleep, mild pain) | Treatment for specific conditions |
| Prescription Required | No | Yes |
| Regulation | Classed as a food supplement | Classed as a controlled medicine |
| Examples | Oils, gummies, skincare, capsules | Sativex, Epidyolex, Nabilone |
While CBD is widely accessible and used for general wellbeing, medical cannabis is reserved for specific medical conditions and only available via prescription.
What is CBD?
CBD (cannabidiol) is a naturally occurring compound found in the cannabis plant. It’s one of over a hundred cannabinoids and has gained popularity for its reported calming, anti-inflammatory, and pain-relieving effects. Unlike THC, CBD doesn’t produce a “high” or intoxication. In the UK, CBD is legally sold as a food supplement, provided it contains less than 0.2% THC. Products range from oils and capsules to edibles and skincare.
The appeal of CBD lies in its potential to support relaxation, manage mild pain, and improve sleep without the psychoactive effects associated with cannabis. However, it's worth noting that CBD's benefits are still being researched, and it's not a replacement for medical treatments.
How Does CBD Work?
CBD interacts with the endocannabinoid system (ECS), a complex cell-signalling system in the body. The ECS helps regulate vital functions like mood, sleep, pain, appetite, and immune response. Instead of directly activating ECS receptors, CBD influences them indirectly, enhancing the body's natural balance (homeostasis). This interaction may explain why users report benefits such as reduced anxiety, improved sleep, and pain relief.
Top Health Benefits of CBD
Chronic Pain Relief
CBD is commonly used to help manage chronic pain, including conditions like arthritis, fibromyalgia, and back injuries. Its anti-inflammatory properties may provide relief, although it's important to consult a healthcare professional before using CBD for long-term pain management.
Anxiety and Mental Health Support
Many users turn to CBD to help with stress, anxiety, and sleep difficulties. While anecdotal evidence is promising, more clinical research is needed to confirm these benefits. It’s always wise to seek medical advice if you’re struggling with mental health issues.
Epilepsy Treatment
One of CBD's most established medical uses is in treating certain types of epilepsy. Epidyolex, a purified CBD medicine, is approved in the UK for severe forms of epilepsy in children. This highlights the potential of CBD in specific medical contexts under strict supervision.
Cancer Patient Support
Some cancer patients use CBD to help manage symptoms like nausea, vomiting, pain, and appetite loss associated with chemotherapy. While some studies suggest CBD may inhibit tumour growth, more research is needed, and it’s not a standalone cancer treatment.
Diabetes and Heart Health
Preliminary research suggests CBD may offer antioxidant and anti-inflammatory benefits that support cardiovascular and metabolic health. These include lowering blood sugar, reducing vascular inflammation, and helping with circulation. However, more robust evidence is needed before CBD can be recommended for these conditions.
CBD and COVID-19 Research
Emerging studies have explored whether CBD might help modulate the inflammatory response seen in severe COVID-19 cases. However, CBD is not an approved treatment for COVID-19 and should only be used under medical guidance.
CBD and Skin Health
CBD’s antioxidant and anti-inflammatory properties make it a popular ingredient in skincare. It’s used in products to help with redness, irritation, and dryness. While initial results are promising, more research is needed to confirm its long-term effectiveness.
CBD for Pets
Some pet owners use specially formulated CBD products to support their animals' wellbeing, particularly for anxiety and joint issues. Always consult a vet before giving pets CBD, and only use products designed for animal use.
CBD Dosage Guide
Finding the right CBD dose depends on factors like body weight, health conditions, and individual sensitivity. Start with a low dose and gradually increase until you find what works for you.
| Purpose | Starting Dose | Notes |
|---|---|---|
| Mild anxiety | 10–20 mg/day | Increase slowly if needed |
| Chronic pain | 25–50 mg/day | Split morning and night |
| Severe epilepsy | 200–300 mg/day | Only under medical supervision |
| General wellbeing | 5–15 mg/day | Great for sleep and relaxation |
Always consult your GP or healthcare provider before starting CBD, especially if you're on medication or managing a health condition.
FAQs About CBD and Medical Cannabis
Is CBD the same as medical cannabis?
No. CBD is a single compound used in wellness products, while medical cannabis can contain THC and is prescribed for specific conditions.
Can I get CBD on the NHS?
No. Over-the-counter CBD is not available on the NHS. However, certain medical cannabis products like Epidyolex may be prescribed for conditions such as epilepsy.
Will medical cannabis make me high?
Some medical cannabis products contain THC, which can produce a “high”. Others, like Epidyolex, do not.
Can I travel with CBD or medical cannabis?
CBD that complies with UK law can generally be taken abroad, but always check local laws. Medical cannabis is more restricted and may require permits.
Navigating Your Options
Whether you’re exploring CBD for general wellness or considering medical cannabis under a doctor’s care, knowing the differences is key. CBD can be a great addition to your daily routine, supporting relaxation, sleep, and mild pain relief. Medical cannabis, on the other hand, is reserved for serious conditions and comes with strict legal controls. If in doubt, chat with your GP or a qualified specialist for advice.
