Arthritis is a disorder that causes inflammation and pain of one or more joints. Studies have shown cannabinoids have anti-arthritic effects and can help manage pain and inflammation associated with the disorder.
Overview of Arthritis
Arthritis is a condition characterized by joint pain. There are 100 different types of arthritis, according to the Arthritis Foundation, but common symptoms among all the types include swelling, pain, stiffness and decreased range of motion.
The most common type of arthritis is osteoarthritis, or degenerative joint disease, which is the wearing down of the protective cartilage on the ends of bones. Another common type is rheumatoid arthritis, which is when the body’s immune system mistakenly attacks healthy cells, including the synovium that lines the joints. Other more common types of arthritis include juvenile arthritis, which develops in children; psoriatic arthritis, which affects people with psoriasis; infectious arthritis, which is an infection that spreads to a joint; and gout, which is caused by the buildup of uric acid.
The pain, swelling and stiffness associated with arthritis can fluctuate in severity and varies between individual. Severe arthritis can cause such intense chronic pain that the ability to maintain daily activities is affected.
Arthritis treatment focuses on relieving pain and swelling with medications, physical therapy, and in some cases, surgery.
Findings: Effects of Cannabinoids and CBD on Arthritis
Preclinical trials suggest that cannabis can help limit the damage of different types of arthritis. In an animal trial, cannabidiol (CBD), a major cannabinoid found in cannabis, effectively blocked the progression of arthritis. Researchers found that CBD protected joints against severe damage and concluded that CBD offers a potent anti-arthritic effect6.
Other studies have found that cannabinoids offer strong anti-inflammatory and immunosuppressive properties and reduce joint damage in mice with osteoarthritis8,9. Most recently, cannabinoid treatments were found effective for reducing osteoarthritis-related cartilage breakdown4.
Research has also shown that cannabis can help manage the pain and inflammation associated with arthritis. CBD, and another major cannabinoid found in cannabis — tetrahydrocannabinol (THC) — activate the two main cannabinoid receptors (CB1 and CB2) of the endocannabinoid system within the body. These receptors regulate neurotransmitter release and central nervous system immune cells to reduce pain11. Activating the CB1 receptor has been specifically found to reduce pain sensitivity in the osteoarthritic knee joints of rats7. One study found that cannabis-based medicine significantly improved pain during joint movement, pain while at rest, and quality of sleep in patients with rheumatoid arthritis3. Numerous preclinical studies have confirmed cannabis’ anti-inflammatory and pain-relieving effects and they support the idea that the endocannabinoid system is involved in alleviating pain associated with arthritis5.
States That Have Approved Medical Cannabis for Arthritis
Currently, Arkansas, California, Illinois (osteoarthritis, rheumatoid arthritis), and New Mexico have approved medical cannabis for the treatment of arthritis.
However, in Washington D.C., any condition can be approved for medical cannabis as long as a DC-licensed physician recommends the treatment. In addition, various other states will consider allowing medical cannabis to be used for the treatment of arthritis with the recommendation from a physician. These states include: Connecticut (other medical conditions may be approved by the Department of Consumer Protection), Massachusetts (other conditions as determined in writing by a qualifying patient’s physician), Nevada (other conditions subject to approval), Oregon (other conditions subject to approval), Rhode Island (other conditions subject to approval), and Washington (any “terminal or debilitating condition”).
Several states have approved medical cannabis specifically to treat “chronic pain,” which is a symptom commonly associated with multiple sclerosis. These states include: Alaska, Arizona, California, Colorado, Delaware, Hawaii, Maine, Maryland, Michigan, Montana, New Mexico, Ohio, Oregon, Pennsylvania, Rhode Island, Vermont, and West Virginia. The states of Montana, Nevada, New Hampshire, North Dakota, Ohio and Vermont allow medical cannabis to treat “severe pain.” The states of Arkansas, Minnesota, Ohio, Pennsylvania, Washington, and West Virginia have approved cannabis for the treatment of “intractable pain.”

CBD found to have anti-inflammatory and immunosuppressive effects, and therefore shown to be a potent anti-arthritic.

This research speculates that a deficiency of cannabinoids can be at the root of autoimmune diseases like lupus, rheumatoid arthritis, diabetes and more.
I just want to share my experience with CBD. It works well for me. I have rheumatoid arthritis, and I use water soluble BioCBDplus on my knees, knuckles and fingers. I really helps me sleep better at night. – Sherry
I can definitely agree that CBD works. I’ve tried a few of water soluble BioCBDplus that were given to me by a friend, and they are definitely helping my arthritis pain. -Sharon
I have back neck and joint pain what is the best milligrams and how much
Hi Shirley,
Many individuals start with 50mg daily of CBD and up the amount as they desire, however, we suggest you contact your healthcare practitioner for any specific questions.
