Cannabidiol (CBD) is a type of cannabinoid, a chemical found naturally in cannabis (marijuana and hemp) plants. CBD doesn’t cause the “high” feeling often associated with cannabis. That feeling is caused by tetrahydrocannabinol (THC), a different type of cannabinoid.
Some people with chronic pain use CBD products, in particular CBD oil, to manage their symptoms. CBD oil may reduce:
overall discomfort related to a variety of health conditions
The research on CBD products and pain management has been promising. CBD can offer an alternative for people who have chronic pain and rely on medications, such as opioids, that can be habit-forming and cause more side effects. However, more research is needed to verify the pain-relieving benefits of CBD oil and other products.
Keep reading to learn more about the potential benefits of CBD use for pain. You can also talk with your doctor to see if it’s an option for your condition.
CBD for chronic pain relief
Everyone has a cell-signaling system known as the endocannabinoid system (ECS). Some researchers think that CBD interacts with a core component of the ECS — endocannabinoid receptors in your brain and immune system.
Receptors are tiny proteins attached to your cells. They receive signals, mostly chemical ones, from different stimuli and help your cells respond.
This response creates anti-inflammatory and pain-relieving effects that help with pain management. This means that CBD oil and other products may benefit people with chronic pain, such as chronic back pain.
One 2018 review assessed how well CBD works to relieve chronic pain. The review looked at studies conducted between 1975 and March 2018. These studies examined various types of pain, including:
Based on these studies, researchers concluded that CBD was effective in overall pain management and didn’t cause negative side effects.
CBD for arthritis pain relief
A 2016 study looked at CBD use in rats with arthritis. Researchers applied CBD gel to rats for four days in a row. The rats received either 0.6, 3.1, 6.2, or 62.3 milligrams (mg) per day. The researchers noted reduced inflammation and overall pain in the rats’ affected joints. There were no obvious side effects.
Rats who received low doses of 0.6 or 3.1 mg didn’t improve their pain scores. The researchers found that 6.2 mg/day was a high enough dose to reduce the rats’ pain and swelling.
In addition, rats who received 62.3 mg/day had similar outcomes to the rats that received 6.2 mg/day. Receiving a substantially larger dosage didn’t result in them having less pain. The anti-inflammatory and pain-relieving effects of CBD gel could potentially help people with arthritis. However, more human studies are needed.
CBD for cancer treatment relief
Some people with cancer also use CBD. Research on mice has shown that CBD can lead to the shrinking of cancerous tumors. However, most studies in humans have investigated the role of CBD in managing pain related to cancer and cancer treatment.
The National Cancer Institute (NCI) has pointed to CBD as a possible option for reducing chemotherapy side effects, such as:
lack of appetite
In a 2010 study on cancer-related pain, study subjects received oral sprays of a combination THC-CBD extract. The THC-CBD extract was used in conjunction with opioids. This study revealed that using the extract provided more effective pain relief than using the opioids alone.
A 2013 study on THC and THC-CBD oral sprays had a similar finding. Many researchers from the 2010 study worked on this study as well. More evidence is still needed.
