Medical Cannabis for Spinal Cord Injury Pain: Neuropathic Relief in the UK

Pain After Spinal Cord Injury: Why It Is So Difficult to Treat

• Approximately 50,000 people in the UK live with a spinal cord injury (SCI)
• Up to 80% of SCI patients experience chronic pain — both neuropathic and musculoskeletal
• Neuropathic SCI pain is described as burning, stabbing, or electric — and is often constant
• Below-level pain occurs in dermatomes below the injury site and is particularly treatment-resistant
• First-line treatments include gabapentin, pregabalin, amitriptyline, and opioids

Pain management following spinal cord injury is one of the most challenging areas of neurology. Standard analgesics often achieve only partial relief, and high-dose opioid regimens carry significant risks. Medical cannabis has emerged as a promising option for SCI pain, particularly for below-level neuropathic pain that is unresponsive to conventional therapies.

How Cannabinoids Act on Neuropathic Pain Pathways

• CB1 receptors are highly expressed in the spinal cord dorsal horn — the primary pain gate
• THC modulates ascending pain signals and activates descending pain inhibition pathways
• CBD reduces neuroinflammation and may protect damaged neural tissue from further insult
• The combination of THC and CBD (Sativex) is licensed in the UK for MS spasticity — with evidence also applicable to SCI
• Cannabinoids may reduce central sensitisation, a key driver of persistent SCI pain

Sativex (nabiximols) — a 1:1 THC:CBD oromucosal spray — is licensed in several countries specifically for neuropathic pain, and its evidence base overlaps substantially with SCI pain. Beyond Sativex, licensed prescribers in the UK can now offer a broader range of cannabis-based medicines tailored to individual patients with SCI-related pain.

Accessing Cannabis-Based Treatment for SCI Pain in the UK

• SCI pain is one of the accepted indications at most UK licensed prescribing clinics
• A pain specialist or neurology letter documenting the injury and pain history is helpful
• Both dried flower (vaporised) and oil-based preparations are available on prescription
• Muscle spasm and spasticity — common in SCI — may also respond to THC:CBD preparations
• Prescriptions are reviewed regularly to optimise dose and monitor for adverse effects

Patients with spinal cord injury seeking medical cannabis should approach a licensed UK clinic with their full SCI records, including MRI reports and previous analgesic trials. The prescribing clinician will assess both neuropathic pain intensity and any associated spasticity, designing a treatment plan that addresses multiple symptom dimensions.

Quality of Life Outcomes for SCI Patients Using Medical Cannabis

• Patients consistently report meaningful reductions in pain intensity and breakthrough pain episodes
• Sleep improvement is one of the most frequently cited benefits — critical for SCI recovery
• Spasticity reduction allows greater engagement with physiotherapy and rehabilitation
• Many SCI patients report significant reductions in opioid usage after starting cannabis
• Mental health benefits — reduced anxiety and depression — are also commonly reported

For people living with chronic pain following a spinal cord injury, medical cannabis can deliver improvements across multiple quality-of-life domains. The combination of pain relief, sleep improvement, and spasticity reduction is particularly relevant for SCI patients undertaking active rehabilitation. Medical cannabis is most effective when integrated into a comprehensive pain management programme.
