An earlier study also found CBD to be effective in chronic pain relief for conditions like multiple sclerosis and spinal cord injury, although across a much smaller sample size  Wade DT, Robson P, House H, Makela P, Aram J. A preliminary controlled study to determine whether whole-plant cannabis extracts can improve intractable neurogenic symptoms. Clin Rehabil. 2003;17(1):21-29. .
A 2019 study found Sativex to be an “effective and well-tolerated add-on treatment” for patients with severe chronic pain stemming from various ailments. The study identified three types of pain: nociceptive (affecting body tissue), neuropathic (affecting nerves) and mixed pain. Sativex helped treat all three kinds but proved especially effective against neuropathic pain.
Meanwhile, a small 2019 trial suggests a mix of CBD and THC may prove beneficial for people with fibromyalgia, a type of arthritis that results in whole-body pain and fatigue  van de Donk T, Niesters M, Kowal MA, Olofsen E, Dahan A, van Velzen M. An experimental randomized study on the analgesic effects of pharmaceutical-grade cannabis in chronic pain patients with fibromyalgia. Pain. 2019;160(4):860-869. . The study found that, via a single inhalation, a CBD-THC solution performed better than a placebo and either substance on its own.
CBD for Chronic Pain
Various conditions and injuries that damage nerves or the nervous system can result in neuropathic pain. This kind of pain manifests as tingling, numbness, muscle weakness and a sharp, shooting, burning or stabbing pain.
Without the intoxicating properties of its cousin delta-9-tetrahydrocannabinol (THC), cannabidiol (CBD) can provide the human body with a handful of health benefits. Cannabinoids like CBD interact with receptors in the endocannabinoid system, which plays a role in signaling bodily functions, from emotional responses to motor control to energy balance  Mouslech Z, Valla V. Endocannabinoid system: An overview of its potential in current medical practice. Neuro Endocrinol Lett. 2009;30(2):153-179. .
CBD for Pain Relief
In 2018 researchers tested the efficacy of topical CBD gel on participants with osteoarthritis-related knee pain over the course of 12 weeks  Hunter D, Oldfield G, Tich N, Messenheimer J, Sebree T. Synthetic transdermal cannabidiol for the treatment of knee pain due to osteoarthritis. Osteoarthritis and Cartilage. 2018;26:S26. . Participants used either 250 milligrams or 500 milligrams, split into two applications, daily. Overall, participants’ weekly pain levels didn’t improve much with CBD compared to placebo. However, when researchers evaluated the average weekly worst pain scores and Western Ontario and McMaster Universities Arthritis Index (WOMAC) physical function scores, participants who applied 250 milligrams of CBD daily experienced significant improvement over placebo participants.
As with other natural products, there is potential for adverse reactions when taken with other medications, especially those that come with grapefruit warnings, such as certain blood thinners. These warnings indicate that certain medications should not be taken with products containing grapefruit.
CBD requires more research in order to prove and explain its effectiveness as well as to better understand potential side effects (especially long-term) and potential drug interactions.
Cannabidiol, commonly referred to as CBD, is a new and relatively understudied treatment for pain, including back pain. Studies suggest it may help relieve inflammation, which is often a factor in chronic back pain. 1
The cannabis sativa plant has two main varieties that are grown for specific purposes:
Potential Risks and Side Effects of CBD
While CBD is present in both varieties, many of the CBD products available to consumers are from the hemp plant. CBD does not come with the high or psychogenic effects of marijuana.
More severe side effects, while rare, include:
CBD is available in many forms; topical creams and gels have shown promising results for inflammation and neuropathy, which may make them a good option for back and neck pain. 2
What Is CBD?
CBD oil is derived from a plant called cannabis sativa. The plant has over 100 chemical compounds, called cannabinoids, that have a range of effects, including anti-inflammatory and analgesic (pain relieving) qualities.
Advocates of CBD believe it can be used to treat a range of conditions in addition to back pain, such as anxiety-related disorders. 5
