Could cannabis compound soothe arthritis pain? January 8th, 2014 admin Latest News Shares Comments Could cannabis compound soothe arthritis pain? “Synthetic cannabis-like molecule developed in lab could help osteoarthritis sufferers,” reports The Daily Telegraph. Anecdotal reports of cannabis’s ability to soothe chronic pain conditions such as osteoarthritis have been available for many years. Aside from the obvious legal issues (cannabis is a Class B illegal drug), cannabis also carries the risk of side effects and complications such as psychosis and depression. So a compound containing the drug’s painkilling ability without its psychoactive effects could lead to useful new treatments. One candidate is “JWH133” a chemical that binds to and activates the cannabinoid 2 (CB2) receptor. Receptors are proteins found on the surfaces of cells. When activated receptors cause a response inside cells. The CB2 receptor is also activated by tetrahydrocannabinol (THC), the principle psychoactive constituent in cannabis. Activating the CB2 receptor is thought to relieve pain and inflammation. The new research found evidence that JWH133 relieves pain in a rat model of arthritis. Importantly, the JWH133 compound is selective for CB2 receptors and does not activate cannabinoid 1 (CB1) receptors. CB1 receptors are found in the brain and are believed to be responsible for the psychological effects of cannabis. So this suggests JWH133 may be a useful candidate for an osteoarthritis treatment. However, this is very early stage research only involving rats. As Professor Alan Silman, medical director of Arthritis UK, says in the press coverage, this research does not support recreational cannabis use. Where did the story come from? The study was carried out by researchers from the University of Nottingham in the UK in collaboration with researchers from the University of Pittsburgh and Virginia Commonwealth University in the US. It was funded by Arthritis Research UK and the National Institutes of Health. The study was published in the peer-reviewed journal PLOS One. PLOS One is an open-access journal, meaning that all the research it publishes can be accessed for free. This study was reported on by the Daily Express and The Telegraph. The Telegraph made no mention of the fact that the current research was in rats. This was also unclear from the over-optimistic headline in the Express. However, the report in the Express was of a higher standard, as it explained that the research was in animals and that it would take a considerable amount of time before any pill could be available for patients.
