This research project will investigate the chronic pain that commonly occurs after spinal cord injury.
Using advanced brain imaging and other assessments, the project aims to:
(a) examine if 6-week treatment with CBD can reduce neuropathic pain
(b) to better understand the specific changes occurring in the brain after SCI that lead to the development of chronic neuropathic pain.
Chief Investigator: Professor Luke Henderson (Brain and Mind Centre, School of Medical Sciences, University of Sydney)
Trial Coordinator: Anastasia Suraev (Lambert Initiative, University of Sydney)

Cannabis and THC have efficacy against neuropathic pain, however, this is hampered by their side effects. It has been suggested that co-administration with CBD might enhance the analgesic actions of THC and minimise its deleterious side effects. We examined the basis for this phytocannabinoid interaction in a mouse model of neuropathic pain.
Results: We found that THC and CBD reduced neuropathic pain. CBD had no adverse side effects. The 1:1 combination of THC and CBD synergistically reduced neuropathic pain with 100-fold greater efficacy than predicted from an additive interaction. THC also synergistically enhanced the efficacy of current first-line neuropathic pain treatments gabapentin and duloxetine.
This was a collaboration between the Lambert Initiative for Cannabinoid Therapeutics at the University of Sydney; the Kolling Institute; Royal North Shore Hospital; the Pain Management Research Institute at the University of Sydney, and the Northern Clinical School at the University of Sydney.
