A preliminary study evaluating self-reported effects of cannabis and cannabinoids on neuropathic pain and pain medication use in people with spinal cord injury

/by

Approximately 60% of individuals with a spinal cord injury (SCI) experience neuropathic pain, which often persists despite the use of various pharmacological treatments. Increasingly, the potential analgesic effects of cannabis and cannabinoid products have been studied; however, little research has been conducted among those with SCI-related neuropathic pain. Therefore, the primary objective of the study was to investigate the perceived effects of cannabis and cannabinoid use on neuropathic pain among those who were currently or had previously used these approaches. Additionally, the study aimed to determine if common pain medications are being substituted by cannabis and cannabinoids.

Medical Cannabis Alleviates Chronic Neuropathic Pain Effectively and Sustainably without Severe Adverse Effect: A Retrospective Study on 99 Cases

/by

Medical cannabis may provide a treatment option for chronic neuropathic pain. However, empirical disease-specific data are scarce. This is a retrospective observational study including 99 patients with chronic neuropathic pain. These patients received medical cannabis by means of inhaling dried flowers with tetrahydrocannabinol content of <12–22% at a maximal daily dose of 0.15–1 g. Up to six follow-ups were carried out at intervals of 4–6 weeks. Pain severity, sleep disturbance, general improvement, side effects, and therapy tolerance at the follow-up consultations were assessed in interviews and compared with the baseline data using non-parametric Wilcoxon signed-rank test.

2074P Oral cannabidiol for prevention of chemotherapy-induced peripheral neuropathy

/by

Chemotherapy-induced peripheral neuropathy (CIPN) is experienced by 37–84% of patients during and/or after end-of-treatment and often results in discontinuation of anti-neoplastic treatment and impairment of health-related quality of life. Cannabidiol (CBD) has shown preventive effects in CIPN animal models without compromising chemotherapy efficacy.

A type II cannabis extract and a 1:1 blend of Δ(9)-tetrahydrocannabinol and cannabidiol display distinct antinociceptive profiles and engage different endocannabinoid targets when administered into the subarachnoid space

/by

Cannabis extracts are being increasingly used to mitigate chronic pain. Current guidelines for their prescription rely on Δ9-tetrahydrocannabinol (THC) and cannabidiol (CBD) content as well as the ratio of these major cannabinoids present in the blend. Here we assessed whether these descriptors were representative of product effectiveness to produce a desired outcome such as analgesia.

Cannabis constituents for chronic neuropathic pain; reconciling the clinical and animal evidence

/by

Chronic neuropathic pain is a debilitating pain syndrome caused by damage to the nervous system that is poorly served by current medications. Given these problems, clinical studies have pursued extracts of the plant Cannabis sativa as alternative treatments for this condition. The vast majority of these studies have examined can- nabinoids which contain the psychoactive constituent delta-9-tetrahydrocannabinol (THC). While there have been some positive findings, meta-analyses of this clinical work indicates that this effectiveness is limited and hampered by side-effects. This review focuses on how recent preclinical studies have predicted the clinical limita- tions of THC-containing cannabis extracts, and importantly, point to how they might be improved. This work highlights the importance of targeting channels and recep- tors other than cannabinoid CB1 receptors which mediate many of the side-effects of cannabis.
