A growing body of clinical research and a history of anecdotal evidence support the use of cannabis for the relief of some types of chronic pain, including neuropathic pain, and spasticity (ie, stiffness or tightness) associated with multiple sclerosis. 1 In a recent comprehensive review of existing data on the health effects of cannabis and cannabinoids, the National Academies of Science concluded that adult patients with chronic pain who were treated with cannabis/cannabinoids were more likely to experience a clinically significant reduction in pain symptoms. 2 They rated these effects as “modest.”
Where does this leave chronic pain patients interested in trying medical cannabis? Regardless of the strain or form of cannabis, the key is the amount of THC and CBD in the final product, according to Dr. Bearman.
“There is little consistency in plant constituents between products’ strain names,” said David Bearman, MD, a physician in private practice who specializes in pain management and has more than 40 years of experience in managing substance abuse. “These names are mainly marketing tools and tell little about the constituents of the product. The best advice is to read the label and understand it.”
The Amount of CBD or THC You Use Matters
Hemp products — including oils, extracts, and even “gummies” — aimed at relieving pain and anxiety abound on the internet. But what is hemp and how does it differ from marijuana? The conventional answer is that hemp and marijuana are two different species of the Cannabis genus of plants.
According to the Institute of Medicine of The National Academies, 100 million Americans live with chronic pain. Along with drastically reducing quality of life, chronic pain can increase healthcare costs and have a negative impact on productivity at work.
So far, much of the evidence for CBD oil’s effects on pain management comes from animal-based research. This research includes a study published in the journal Pain in 2017, in which scientists observed that treatment with topical CBD helped thwart the development of joint pain in rats with osteoarthritis.
Potential Benefits of CBD Oil
Chronic pain is the most common reason for medicinal cannabis use, according to a recent survey. If you have a chronic pain condition and have not been able to manage it with standard treatment (or wish to avoid the adverse effects of other medications), you may be considering CBD oil for pain relief.
A type of pain triggered by damage to the somatosensory system (i.e., the system responsible for processing sensory stimuli), neuropathic pain often occurs in people with conditions like diabetes and multiple sclerosis.
In studies using varied doses, routes of administration, and combination or whole products with THC, a number of side effects have been reported. These include anxiety, changes in appetite and mood, diarrhea, dizziness, drowsiness, dry mouth, low blood pressure, mental confusion, nausea, and vomiting.
