Summer in the UK brings longer days and more opportunities for activity, but for those living with chronic pain conditions like arthritis, neuropathic pain, and migraines, it can also present unique challenges. As you consider or use medical cannabis for pain relief, it’s essential to understand the different roles of its two primary cannabinoids: Cannabidiol (CBD) and Tetrahydrocannabinol (THC). Both have pain-relieving properties, but they work distinctly and are regulated differently in the UK.
What is CBD?
CBD is a non-intoxicating cannabinoid, meaning it will not produce the “high” associated with cannabis. It interacts with the body’s endocannabinoid system (ECS) and other receptor systems in various ways:
- Anti-inflammatory: CBD is well-known for its potent anti-inflammatory properties, which can be particularly beneficial for pain linked to inflammation, such as certain types of arthritis.
- Modulates Pain Signals: While not directly binding to cannabinoid receptors in the same way as THC, CBD can influence pain signalling pathways, potentially reducing the perception of pain.
- Calming Effect: Many users report that CBD provides a calming and anxiolytic (anxiety-reducing) effect. This can be crucial for pain management, as anxiety often exacerbates pain perception.
- Sleep Support: By promoting relaxation and reducing anxiety, CBD can also contribute to improved sleep quality, which is vital for overall pain management and recovery.
Potential benefits for pain: CBD is often considered for general aches and pains, inflammation-related pain, and pain where anxiety or sleep disturbances play a significant role.
Availability in the UK: You can find both over-the-counter (non-medical) CBD products (e.g., oils, capsules, balms) in health stores and online, provided they contain less than 1mg of THC per container. However, it’s crucial to note that the quality and regulation of these products can vary significantly. Prescription-grade CBD is also available via a medical cannabis specialist, which is subject to much stricter quality controls and is intended for specific medical conditions.
What is THC?
THC is the primary psychoactive cannabinoid in cannabis, responsible for the “high” sensation. Beyond its recreational effects, THC offers significant therapeutic benefits:
- Direct Pain Relief: THC interacts directly with CB1 receptors in the brain and nervous system, playing a key role in reducing pain signals.
- Muscle Relaxation: THC can help reduce muscle spasticity and tension, which is beneficial for various chronic pain conditions.
- Sleep Aid: Its sedative properties can be very effective in promoting restful sleep, especially for those whose pain disrupts their sleep patterns.
- Appetite Stimulation & Nausea Reduction: While not directly pain-related, these effects can be beneficial for patients struggling with appetite loss or nausea due to their condition or other medications.
Potential benefits for pain: THC is often prescribed for more severe and persistent forms of chronic pain, including neuropathic pain, spasticity (e.g., in MS), and certain types of migraines.
Availability in the UK: THC-containing medical cannabis is strictly prescription-only in the UK. It can only be prescribed by a specialist doctor on the General Medical Council’s (GMC) specialist register, typically after other conventional treatments have been tried without sufficient success.
Comparison Table: CBD vs. THC for Pain Relief
| Feature | CBD (Cannabidiol) | THC (Tetrahydrocannabinol) |
| Psychoactive? | No | Yes |
| Primary Actions | Anti-inflammatory, anxiolytic, pain modulation | Analgesic, muscle relaxant, sedative, appetite stimulant |
| UK Legal Status | Available OTC (low THC) & via prescription | Prescription only for medical use |
| Best For… | General aches, inflammation, anxiety, sleep issues, mild pain | Severe chronic pain, neuropathic pain, spasticity, nausea, acute migraines |
| Common Side Effects | Mild (fatigue, diarrhoea, changes in appetite) | Drowsiness, dizziness, dry mouth, altered perception, anxiety (at high doses) |
Considerations for Specific Pain Conditions in Summer
The choice between CBD, THC, or a combination often depends on the specific type of pain and individual response.
- Arthritis: In warmer weather, increased activity can sometimes exacerbate arthritic pain.
- CBD: Its strong anti-inflammatory properties can be highly beneficial for managing the underlying inflammation in conditions like rheumatoid arthritis or osteoarthritis, helping to reduce swelling and stiffness.
- THC: Can provide more direct pain relief, especially for acute flares, and may improve sleep disrupted by joint pain. A balanced CBD:THC ratio is often explored for comprehensive relief.
- Neuropathic Pain: This type of pain, caused by nerve damage, is notoriously difficult to treat.
- THC: Often considered more effective for neuropathic pain due to its direct interaction with pain receptors in the nervous system. It can help reduce the burning, shooting, or tingling sensations.
- CBD: Can complement THC’s effects by reducing inflammation that might contribute to nerve irritation and by alleviating associated anxiety or sleep problems.
- Migraines: Summer heat, dehydration, and changes in routine can sometimes trigger migraines.
- Both CBD and THC can play a role. THC may help with the acute pain and nausea during a migraine attack, while its sedative properties can aid sleep, which is crucial for recovery.
- CBD: Can help reduce overall inflammation and anxiety that might contribute to migraine frequency or severity. Some patients find a balanced CBD:THC approach effective for managing both acute symptoms and prophylactic benefits.
Important Reminders for UK Patients
- Individual Response Varies: It’s crucial to understand that everyone responds to cannabinoids differently. What works well for one person may not work for another.
- Specialist Consultation is Essential: To determine the most appropriate cannabinoid ratio, dosage, and product form for your specific pain condition and summer needs, you must consult a specialist medical cannabis doctor in the UK. They will conduct a thorough assessment and create a personalised treatment plan.
- Driving & Travel: If prescribed THC-containing medical cannabis, be aware of the legal implications for driving. You must not drive if you feel impaired. When travelling, always check the legal status of medical cannabis in your destination country, as laws vary widely.
- Start Low, Go Slow: If starting medical cannabis or adjusting your dose, always begin with a low dose and increase gradually under medical supervision.
Take Control of Your Summer Pain
