Medical Cannabis in the Treatment of Neuropathy (5020)
2020
Objective: To evaluate the efficacy and adverse effects of medical cannabis (MC) in the treatment of neuropathy. Background: According to the NIH, more than 20 million Americans suffer from neuropathy. With MC now legal in 33 states, MC presents as an anti-inflammatory and neuroprotective agent that may help in treating neuropathy and associated symptoms. Design/Methods: This retrospective chart analysis was conducted on patients with neuropathy as diagnosed by a board-certified neurologist in a neurologic outpatient setting in Buffalo, NY. All patients were certified to use MC as part of New York State’s Medical Marijuana Program. Results: 152 (85=male, 67= female) patients age 22–95 years with neuropathy were included for this analysis. 78.9% of the study population reported benefit from using MC, with 76% percent of patient population (n=116) reporting a decrease in neuropathic pain. 44% (n=67) of the patient population were using an opioid upon initiation of MC treatment, subsequently 22% (n=15) were able to reduce their consumption of opioids. 70% of the study population used only one MC product with the most commonly administered via oral tincture (61%). 20:1 (THC:CBD) and 1:1 (THC:CBD) were the most commonly used ratios, representing more than 80% of MC products. Side effects were reported by 40% (n=61) of the population with the most common being fatigue (11%), increased appetite (4.61%), and euphoria (4.61%). Only 10 patients chose to stop treatment with MC due to side effects. No severe AEs were reported. Conclusions: MC in combination with other neuropathy treatments is largely well tolerated with 78.9% of the population reporting benefit and may have a role in a comprehensive neuropathic care plan. The most common MC ratios used to achieve such results were 20:1 (THC:CBD) and 1:1 (THC:CBD). Further investigations, such as a randomized placebo-controlled trials are needed to confirm these promising results in the treatment of neuropathy.
