Cannabidiol, a non-psychoactive component of marijuana, may help to relieve pain and joint stiffness in people with RA. Here’s what you need to know. If you have chronic arthritis pain, you may have been tempted to try cannabidiol as a treatment, or you may have tried it already. But is there any evidence that it works? Studies are finally addressing this question, and the results are just starting to come in.

As cannabidiol (CBD) has grown in popularity over the years, major organizations like the Arthritis Foundation have released guidelines pertaining to its use in the treatment of rheumatoid arthritis (RA). CBD is a non-psychoactive component of cannabis. The CBD in most products is extracted from hemp, a variety of cannabis that only has traces (up to 0.3%) of THC, the active compound that gets people high. Studies have shown CBD can help reduce chronic pain by impacting endocannabinoid receptor activity, which may also reduce inflammation.
CBD comes in different forms, including oil, vape, edible, and topical. Oils, vapes, and edibles are taken orally, while topical CBD lotions can be applied to the skin. CBD dosage varies depending on the form, the indication, and other treatments being used.
What Is Rheumatoid Arthritis?
RA is an autoimmune inflammatory disease, in which the immune system attacks healthy cells in the body and causes inflammation. RA commonly affects joints in the hands, wrists, and knees, causing the joint lining to become inflamed and damaging the tissue. This causes chronic joint pain and leads to deformity. RA can also affect other tissues throughout the body, such as the lungs, heart, and eyes.

Health Benefits of CBD for RA
Animal studies have suggested that CBD has pain-relieving and anti-inflammatory properties, but these effects have not been validated with quality studies in humans. Anecdotally, some people who have tried CBD for treatment of arthritis symptoms report noticeable pain relief, improved sleep improvement, and reduced anxiety.
The trials that have been conducted in humans have not yielded strong evidence for the use of CBD in managing arthritic pain.
- A randomized trial of topical CBD for treatment of knee osteoarthritis lasted only 12 weeks, and results were mixed.
- One of the largest reviews examining the health effects of cannabis and CBD concluded that there is substantial evidence that cannabis is an effective treatment for chronic pain in adults. There was, however, no specific conclusion regarding CBD, as definitive studies were not available.
- More recently, a new study showed that CBD can potentially help alleviate RA pain and inflammation by acting on immune cells that are attacking healthy cells in the body. It’s important to note that this study was also not conducted with human subjects.
Research in this area is ongoing.
If you are interested in trying CBD for RA pain management, be sure to talk to your healthcare provider first before using any CBD products.
Rising Popularity of CBD for RA
Based on a 2019 national survey of 2,600 people conducted by the Arthritis Foundation, 79% of respondents said they were using CBD, have used it in the past, or were considering using it to help with their arthritis pain.
Health Benefits Related to Arthritis
Given the lack of strong scientific evidence supporting the use of CBD, it is not recommended as the first choice for pain relief in RA.
If you have RA, you should not stop taking your prescribed medications that may be protecting your joints from future damage. You should discuss any changes you want to make to your medication regimen with your healthcare provider.
Additional Health Benefits
The strongest scientific evidence for effectiveness of CBD as a medical treatment is for seizure prevention in Dravet syndrome and Lennox-Gastaut syndrome, which are severe childhood epilepsy disorders that typically don’t respond to antiseizure medications. Several years ago, the FDA approved the first cannabis-derived medicine for these conditions, Epidiolex, which contains CBD.
Other potential health benefits of CBD include:
- Reduce anxiety, insomnia, and depression
- Relieve cancer or cancer treatment symptoms
- Clear acne
- Slow the progress of neurologic disease like Alzheimer’s disease
Possible Side Effects
Treatment with CBD should be started slowly and under the supervision of a healthcare provider, who will oversee its effectiveness and side effects. There have been reports of mild side effects of CBD.
The most common side effects include:
It’s important to note that CBD may interact with other drugs, including some of the medications that are prescribed for the treatment of RA.
Warnings and Interactions
There are some warnings and adverse drug interactions to be aware of before beginning using CBD for management of RA-associated pain.
Do not stop taking any other treatments without consulting your healthcare provider. Additionally, CBD shouldn’t be a replacement for other therapies you are using.
Pregnant people and children should consult a healthcare provider before using CBD since there isn’t enough research on the effects of CBD on these populations. There has been concern about a possible link between inhaled cannabis and lower-birthweight babies, but it’s not clear if this applies to CBD.
Currently, the U.S. Food and Drug Administration (FDA) does not regulate the safety and purity of CBD products, so you cannot know for sure that the product you buy has active ingredients at the dose listed on the label. The product may contain other unknown elements. The most effective therapeutic dose of CBD for any particular medical condition has not been established.
Are CBD Products Legal?
CBD products derived from hemp are no longer considered schedule I drugs under the federal Controlled Substances Act, but they still remain in a legal gray zone. There are changes underway on federal and state levels that will ultimately clarify the laws and regulations related to CBD-based products and sales. Despite that, they’re widely available in nearly every state and online. People who want to use CBD should check their own state laws.
Studies have found moderate interactions between CBD and medications commonly prescribed for treating RA.
Interactions can occur with these medications:
CBD can increase your level of coumadin, a blood thinner.
CBD may also raise levels of other medications in your blood by the same mechanism that grapefruit juice does.
Medications that interact with grapefruit juice can potentially interact with CBD, including:
- Cholesterol medications
- High blood pressure medications
- Organ-rejection medications
- Anti-anxiety medications
- Heart medications
- Some antihistamines
Preparation and Dosage
If you’ve decided to try CBD for treating your RA pain, the next step is figuring out how much to take.
Your dosage depends on a number of factors:
- Body weight
- Medical indication
- The concentration and form of CBD that you’re taking
You will likely need to start with a low dose and find what works for you. Studies have found extreme differences in dosages, with some people using 5 milligrams (mg) and others as much as 600 mg.
Your healthcare provider may direct you to start with 20-40 mg per day and increase slowly each day until you feel the relief you’re looking for.
To ensure that you are using CBD safely and effectively for pain management, you should:
- Choose an oral treatment (rather than inhaled products) and start with a low dose
- Establish initial goals of treatment within a realistic period of time. For example, a reduction in knee pain that allows you to walk around the block within two weeks of starting treatment; later, if improved, the goals can be adjusted
- Tell your healthcare provider(s) about your planned and current CBD treatment; monitor your pain and adjust medications with your medical providers, rather than with non-medical practitioners
- When preparing to take a liquid form, be aware that the CBD extract is mixed with a carrier oil, so there are two measures to know: the amount of the liquid product to take (the dose) and the amount of CBD in each dose
If CBD alone doesn’t work and you are in a state where medical or recreational marijuana is legal, you could consider talking to your healthcare provider about taking CBD with a very low-dose THC product. Be aware that even at low levels, THC may make you feel high, resulting in cognitive, motor, and balance impairment.
If you experience any unwanted side effects when using a CBD product, immediately discontinue use and inform your healthcare provider.
What To Look For
Look for the following when choosing a CBD product:
- Look for products manufactured in the United States with ingredients grown domestically
- Choose products made by companies that follow good manufacturing practices established by the FDA for pharmaceuticals or dietary supplements or required by the state where they are manufactured
- Buy from companies that test each batch and provide a certificate of analysis from an independent lab that uses validated standardized testing methods approved by the American Herbal Pharmacopoeia (AHP), the U.S. Pharmacopeia (USP), or the Association of Official Agricultural Chemists (AOAC)
- Avoid companies that claim their products have disease benefits
- Be aware that marketers and people behind retail counters are not health professionals. Your healthcare provider is your best source for guidance and monitoring when using an unregulated product
A Word From Verywell
CBD may sound like an appealing option for pain relief, but do your due diligence before jumping on the bandwagon. A lot of people say CBD can help reduce pain and inflammation for those with RA, but not a lot of strong scientific data have substantiated that claim. That said, serious effects are not commonly associated with CBD use.
If this is something you are interested in, you can work with your healthcare provider to figure out whether CBD is something you can try safely. Remember that CBD should not be used as a first-line treatment for RA pain and that it’s not advisable to stop taking disease-modifying treatments for RA.

Does CBD help with arthritis pain?
If you have chronic arthritis pain, you may be wondering about cannabidiol (CBD) as a treatment. CBD, along with delta-9-tetrahydrocannabinol (THC) and other chemicals, is found in marijuana. But unlike THC, CBD is not “psychoactive” — that is, it does not cause the intoxication or high associated with marijuana use.
There’s a good chance you’ve tried it already: according to a Gallup poll in August of 2019, about 14% of Americans report using CBD products, and the number one reason is pain. The Arthritis Foundation conducted its own poll and found that 29% reported current use of CBD (mostly in liquid or topical form), and nearly 80% of respondents were either using it, had used it in the past, or were considering it. Of those using it, most reported improvement in physical function, sleep, and well-being; of note, a minority reported improvement in pain or stiffness.
Perhaps you’ve been tempted to try it. After all, most types of arthritis are not cured by other treatments, and CBD is considered a less addictive option than opiates. Or maybe it’s the marketing that recommends CBD products for everything from arthritis to anxiety to seizures. The ads are pretty hard to miss. (Now here’s a coincidence: as I was writing this, my email preview pane displayed a message that seemed to jump off the screen: CBD Has Helped Millions!! Try It Free Today!)
What’s the evidence it works? And what do experts recommend? Until recently, there’s been little research and even less guidance for people (or their doctors) interested in CBD products that are now increasingly legal and widely promoted.
But now, there is.
A word about arthritis pain
It’s worth emphasizing that there are more than 100 types of arthritis, and while pain is a cardinal feature of all of them, these conditions do not all act alike. And what works for one may not work for another. Treatment is aimed at reducing pain and stiffness and maintaining function for all types of arthritis. But for certain conditions, such as rheumatoid arthritis, conventional prescription medications are highly recommended, because these drugs help prevent permanent joint damage and worsening disability.
In addition, individuals experience pain and respond to treatment in different ways. As a result, it’s highly unlikely that there is a single CBD-containing product that works for all people with all types of arthritis.
What’s the evidence that CBD is effective for chronic arthritis pain?
While there are laboratory studies suggesting CBD might be a promising approach, and animal studies showing anti-inflammatory and pain-relieving effects, well-designed studies demonstrating compelling evidence that CBD is safe and effective for chronic arthritis pain in humans do not exist. A randomized trial of topical CBD for osteoarthritis of the knee has been published, but in abstract form only (meaning it’s a preliminary report that summarizes the trial and has not been thoroughly vetted yet); the trial lasted only 12 weeks, and results were mixed at best. One of the largest reviews examined the health effects of cannabis and CBD, and concluded that there is “substantial evidence that cannabis is an effective treatment for chronic pain in adults.” But there was no specific conclusion regarding CBD, presumably because definitive studies were not available.
Of course, there is anecdotal evidence and testimonials galore, including reports of dramatic improvement by people who tried CBD in its various forms (including capsule, liquid, topical, and spray) for their pain. But we are still waiting for well-designed, scientifically valid, and rigorous clinical trials (such as this one in progress) that are so badly needed to answer the question of just how helpful CBD may be to people with chronic arthritis pain.
Are there downsides to CBD treatment?
As with any treatment, there can be downsides. CBD is generally considered safe; however, it can still cause lightheadedness, sleepiness, dry mouth, and rarely, liver problems. There may be uncertainty about the potency or purity of CBD products (since they are not regulated as prescription medications are), and CBD can interact with other medications. For pregnant women, concern has been raised about a possible link between inhaled cannabis and lower-birthweight babies; it’s not clear if this applies to CBD. Some pain specialists have concerns that CBD may upset the body’s natural system of pain regulation, leading to tolerance (so that higher doses are needed for the same effect), though the potential for addiction is generally considered to be low.
There is one definite downside: cost. Prices range widely but CBD products aren’t inexpensive, and depending on dose, frequency, and formulation, the cost can be considerable — I found one brand that was $120/month, and health insurance does not usually cover it.
Are there guidelines about the use of CBD for chronic arthritis pain?
Until recently, little guidance has been available for people with arthritis pain who were interested in CBD treatment. Depending on availability and interest, patients and their doctors had to decide on their own whether CBD was a reasonable option in each specific case. To a large degree that’s still true, but some guidelines have been published. Here’s one set of guidelines for people pursuing treatment with CBD that I find quite reasonable (based on recommendations from the Arthritis Foundation and a recent commentary published in the medical journal Arthritis Care & Research):
- If considering a CBD product, choose one that has been independently tested for purity, potency, and safety — for example, look for one that has received a “Good Manufacturing Practices” (GMP) certification.
- CBD should be one part of an overall pain management plan that includes nonmedication options (such as exercise) and psychological support.
- Choose an oral treatment (rather than inhaled products) and start with a low dose taken in the evening.
- Establish initial goals of treatment within a realistic period of time — for example, a reduction in knee pain that allows you to walk around the block within two weeks of starting treatment; later, if improved, the goals can be adjusted.
- Tell your doctor(s) about your planned and current CBD treatment; monitor your pain and adjust medications with your medical providers, rather than with nonmedical practitioners (such as those selling CBD products).
- Don’t make CBD your first choice for pain relief; it is more appropriate to consider it if other treatments have not been effective enough.
- Don’t have nonmedical practitioners (such as those selling CBD products) managing your chronic pain; pain management should be between you and your healthcare team, even if it includes CBD.
- For people with rheumatoid arthritis or related conditions, do not stop prescribed medications that may be protecting your joints from future damage; discuss any changes to your medication regimen with your doctor.
The bottom line
If you’re interested in CBD treatment for chronic arthritis pain or if you’re already taking it, review the pros, cons, and latest news with your healthcare providers, and together you can decide on a reasonable treatment plan. Depending on the type of arthritis you have, it may be quite important to continue your conventional, prescribed medications even if you pursue additional relief with CBD products.
We may not have all the evidence we’d like, but if CBD can safely improve your symptoms, it may be worth considering.
