Evidence Note: Evidence strength varies by condition. Chronic pain and epilepsy have the strongest clinical evidence base. Other conditions are treated based on specialist clinical judgement and emerging research. All prescriptions require specialist assessment.
Neuropathic pain — pain caused by damage or dysfunction of the nervous system — affects an estimated 8% of the UK adult population. It arises from diverse causes including diabetic peripheral neuropathy, post-herpetic neuralgia, chemotherapy-induced neuropathy, multiple sclerosis, and spinal cord injury. Standard treatments (anticonvulsants, antidepressants, opioids) leave many patients with inadequate pain control.
How Cannabinoids Modulate Nerve Pain
Unlike traditional analgesics, cannabinoids act through a distinct mechanism: activation of CB1 receptors in the dorsal horn of the spinal cord and peripheral sensory neurons reduces nociceptive signal transmission. THC and CBD also interact with TRPV1 channels and glycine receptors implicated in central sensitisation — a key driver of chronic neuropathic pain.
Clinical Evidence for Neuropathic Pain
Neuropathic pain is one of the most evidence-supported indications for cannabis-based medicines. A 2018 Cochrane review analysed 16 RCTs and found that cannabis-based medicines produced clinically significant reductions in neuropathic pain scores compared to placebo. The NICE guideline NG173 (Chronic Pain, 2021) acknowledges that cannabis-based medicinal products may be considered in the context of a specialist pain clinic for patients who have not responded to other treatments.
Types of Neuropathic Pain Treated

Chemotherapy-induced peripheral neuropathy (CIPN)
Post-herpetic neuralgia (shingles-related)

Spinal cord injury pain
Complex regional pain syndrome (CRPS)
Frequently Asked Questions
Is medical cannabis effective for nerve pain?
Yes. Neuropathic pain is among the most evidence-supported indications for cannabis-based medicines. Multiple RCTs and a 2018 Cochrane review demonstrate clinically significant pain reductions compared to placebo. Cannabinoids work through distinct mechanisms (CB1 receptor activation, TRPV1 modulation) that complement rather than duplicate existing treatments.
Can I get medical cannabis for diabetic nerve pain in the UK?
Yes. Diabetic peripheral neuropathy is one of the most common conditions for which UK specialists prescribe cannabis-based medicines. A GMC-registered pain specialist or cannabis clinician can assess suitability if standard treatments (gabapentin, pregabalin, duloxetine) have not provided adequate relief.
Will medical cannabis work alongside my existing nerve pain medication?
Cannabis-based medicines can often be used alongside anticonvulsants (gabapentin, pregabalin) and antidepressants (duloxetine, amitriptyline). Some patients reduce their existing medication dose as cannabis efficacy establishes. Never adjust your doses without specialist supervision.
What type of medical cannabis is prescribed for neuropathic pain?
Most UK pain specialists prescribe THC-containing preparations for neuropathic pain, given that THC has the strongest direct analgesic action at CB1 receptors. Balanced CBD:THC formulations are often preferred to mitigate psychoactive effects. Vaporised flower provides rapid onset for acute exacerbations; oils provide sustained background relief.
