The study, published in , found that CBD administered with THC in a drug called Sativex reduced pain and improved sleep quality in patients with rheumatoid arthritis 6. For example, in a study, scientists artificially induced symptoms of osteoarthritis OA in rats and treated the affected joints with CBD 7. Rats treated with CBD had less inflammation, decreased pain response, and were able to bear more weight on the arthritic limb.
The authors suggest that CBD could be effective at inhibiting pain and inflammation when administered around the joint. We have some early evidence that CBD may help treat the pain and swelling of arthritis, but more clinical studies in humans are required before we can draw firm conclusions. At the time of this writing, there is one human trial registered in ClinicalTrials. This study will help add to our understanding of whether CBD can provide safe, reliable relief for patients with arthritis.

Peripheral receptor targets for analgesia: Characterisation of the cannabinoid receptor system in synovial tissue and fluid in patients with osteoarthritis and rheumatoid arthritis. The aim of this study was to determine whether CBD is anti-nociceptive in OA, and whether inhibition of inflammation by CBD could prevent the development of OA pain and joint neuropathy.

These were patients on high doses of opioids to where more would not relieve pain. In Study-1, patients were randomized to Sativex or placebo, and then self-titrated patient chooses the number of doses study medications over a 2-week period to gauge effect and tolerability, followed by a 3-week treatment period.
In Study-2, all patients self-titrated Sativex over a 2-week period. Overall, Sativex did not statistically demonstrate superiority to placebo in reducing self-reported pain in advanced cancer patients with chronic pain unalleviated by opioid therapy. In addition, treatment effect in favour of Sativex was observed on quality-of-life questionnaires. This study examined the effectiveness of cannabidiol used transdermally absorption through the skin on inflammation and pain on arthritis.
It was noted before the study that CBD has been shown to reduce inflammation and pain without side-effects, but CBD does not mix well with water and has poor oral bioavailability. Result showed that CBD concentrations in the blood and other plasma were in direct proportion to dosages given.
Transdermal CBD gel significantly reduced joint swelling, limb posture scores as a rating of spontaneous pain, immune cell infiltration — all in a dose dependent manner, meaning the higher the dose, the greater the effectiveness.
Results showed from 6. Using mice subjects, this study wished to examine the ability of intense cannabidiol pretreatment to prevent paclitaxel-induced pain sensitivity was assessed. The effect of CBD on stimulus conditioning and on an learning and memory tasks was also assessed.
In addition, the potential interaction of CBD and paclitaxel on breast cancer cell viability was determined using human cell cultures in a lab dish.
The results showed paclitaxel-induced pain sensitivity was prevented by administration of cannabidiol and that it is protective against induced neurotoxicity. The pathway receptor that was demonstrated in this case was the 5-HT1A receptor. CBD did not demonstrate any cognitive impairment. It did not interfere with conditioned rewarding effects and did not affect conditioned learning and memory.
This review presents cannabinoids, and specifically cannbidiol, as possible therapeutic agents for pain and chronic pain, including neuropathic pain. It found some conflicting data on whether CBD inhibits or enhances the effects of THC when both are administered — for those trials addressing that aspect.
CBD was directly involved with this study. The study wanted to report on what mechanisms how it works are used when cannabidiol is administered. They did by subjecting two mice subject groups to chronic pain induced by chemicals.
This was to see if this receptor was the influential receptor for pain. They showed that CBD and DH-CBD significantly suppress chronic inflammatory and neuropathic pain without causing apparent analgesic tolerance in rodents. No cause of analgesic tolerance meant that they did not build up a tolerance which would create a need for more CBD to have the same effect. CBD may be a treatment to reduce pain in those getting the chemotherapy drug paclitaxel.
Results of this study showed cannabidiol has pain- and inflammation-reducing effects, while avoiding the psychoactive side effects. In female mice, cannabidiol reduces paclitaxel-induced neuropathy, which is a potentially serious complication. Paclitaxel, commonly used in the treatment of advanced breast or ovarian cancer, can cause neuropathy, or nerve damage, leading to symptoms like pain, numbness, or tingling.
This type of pain can prevent patients from getting their full course of chemotherapy. The aim of this study was to examine whether cannbidiol had any effect on pain and neuropathic pain in female rat subjects. Femail rats were chosen specifically because there were stuides with male rats but not enough with female rats. By inducing allodynia pain with a chemotherapy drug known to cause pain paclitaxel and testing CBD effectiveness, they were able to show that CBD prevented the pain in female rat subjects.
The role microglial cells in diabetic neuropathic pain was a focus of this study and how these cells might be influenced by cannabinoid receptors and cannbinoids.
