Medical Cannabis for Arthritis Pain: What the Research Shows
The short answer on medical cannabis for arthritis is honest rather than exciting. In the strongest trial so far, people with painful knee osteoarthritis who took oral CBD for eight weeks did no better than those on a placebo [1]. Smaller open-label and observational studies point in mixed directions, and there is no controlled trial in rheumatoid arthritis to point to yet. Below: what that means for your joints, what is safe, and how to talk it through with a licensed doctor.
This overview draws on randomized controlled trials, cohort and registry studies, and systematic reviews of cannabis and cannabinoids in arthritis.
When Arthritis Pain Comes and Goes: and Keeps Coming Back
Does arthritis pain come and go? For most people, yes, and that is part of what makes it so wearing. A knee can feel almost normal for a week, then flare after a long walk, a busy day on your feet or a night of poor sleep. Hands that type easily on Monday struggle with a jar lid on Thursday. Doctors call these flares, and they are typical of both osteoarthritis and rheumatoid arthritis.
Many people also say their arthritis gets worse when it rains or turns cold. You are not imagining it: falling temperature, damp air and changes in barometric pressure are commonly reported triggers, even though researchers still argue about the exact reason. Cold makes muscles and tendons around a joint stiffer, and people tend to move less on gray days, which lets stiffness set in.
The hardest part is often what pain takes away: a full night’s sleep, the morning walk, gardening, holding a grandchild, buttoning a shirt without thinking about it. Morning stiffness can turn the first hour of every day into a negotiation with your own body.
Then come the limits of the usual medicines. Anti-inflammatory pills can upset the stomach and are not right for everyone with heart or kidney problems. Many people are wary of opioids and the risk of dependence. And some hold back from asking about cannabis at all because they worry about being judged, or about sitting in a clinic waiting room for a conversation that feels awkward. The sections below lay out what is known, what is not, and where cannabis fits among the options.

What Is Arthritis and How Does It Affect Your Life?
Understanding Arthritis: More Than Just “Aches and Pains”
Arthritis is not one disease. The word means joint inflammation, and doctors use it as an umbrella for a large family of conditions that cause pain, swelling and stiffness in the joints. It is one of the most common reasons adults in the U.S. limit their daily activities, and it is not only a condition of old age: it affects working-age adults and, less often, children. The four types people search for most often look quite different under the surface.
Osteoarthritis (OA)
The most common type. Cartilage that cushions the joint wears down, the bone underneath changes and the joint lining can become inflamed. It favors knees, hips, hands, feet and the spine, and usually builds slowly over years.
Rheumatoid arthritis (RA)
An autoimmune disease: the immune system attacks the lining of the joints, usually on both sides of the body at once. Without treatment it can erode bone and affect the heart, lungs and eyes, which is why early care from a rheumatologist matters.
Psoriatic arthritis
Joint inflammation linked to the skin condition psoriasis. It can swell a whole finger or toe like a sausage, inflame the spot where tendons attach to bone and change the nails.
Gout
Uric acid crystals build up in a joint, most famously the big toe joint, and trigger sudden attacks of severe pain, heat and redness, often overnight. Between attacks the joint may feel fine.
The symptoms of arthritis usually include joint pain, stiffness (often worst in the morning or after sitting), swelling, warmth and a shrinking range of motion. Does arthritis cause burning pain? It can: inflamed joints often feel hot or burning, and nearby nerves can be irritated, especially in the neck and back. Can arthritis come on suddenly? Gout and some flares of rheumatoid or psoriatic arthritis can appear within hours, while osteoarthritis tends to creep up. Fatigue is common too, particularly with rheumatoid arthritis, where tiredness is part of the disease itself and not only the result of poor sleep.
Where It Hurts
Arthritis shows up differently depending on the joint, and that shapes both daily life and which treatments make sense.
- Hands and fingers
- Bony knobs at the finger joints, a sore base of the thumb, weak grip and trouble with buttons, jars and keys. Osteoarthritis of the hands and rheumatoid arthritis both commonly start here.
- Knees
- Pain on stairs and when standing up, stiffness after sitting, grinding or swelling. Knee osteoarthritis is the type most studied in cannabis research.
- Feet and the big toe joint
- Arthritis in the feet makes walking and shoe choice harder; the big toe joint is a classic site for both gout and osteoarthritis.
- Back
- Arthritis of the small spinal joints causes stiffness and aching that often eases with movement, and can narrow the space around nerves.
- Neck
- Neck arthritis can limit turning your head and is a known cause of headaches that start at the base of the skull. Dizziness has many causes and deserves its own check-up.
Arthritis ICD-10 Codes
If you are filling out forms, checking a visit summary or preparing records for an appointment, these are the diagnosis code families U.S. clinicians use for the main types of arthritis.
| Type of arthritis | ICD-10-CM codes |
|---|---|
| Osteoarthritis | M15 – M19 (M16 hip, M17 knee, with M17.0 for primary osteoarthritis of both knees; M18 base of thumb; M19 other joints, including the hand) |
| Rheumatoid arthritis | M05 – M06 |
| Gout | M10 (M1A for chronic gout) |
| Psoriatic arthritis | L40.5 |
Source: ICD-10-CM, the U.S. diagnosis code set maintained by the CDC National Center for Health Statistics [2]. Your exact code depends on side, joint and cause; your clinician assigns it.
Arthritis: When to See a Doctor
Recognizing the signs early and getting a proper diagnosis is the single most useful thing you can do for your joints, especially with rheumatoid arthritis, where early treatment helps prevent damage that cannot be undone later. Book an appointment if joint pain keeps returning for weeks, if morning stiffness takes a long time to ease, if a joint looks swollen, red or warm without a clear reason, or if everyday tasks are getting harder.
Get care promptly if:
- a joint swells suddenly, especially if you cannot put weight on it;
- a joint is hot, red and very painful to touch;
- joint pain comes with fever or chills, or you feel generally unwell;
- a joint changes shape, gives way or locks after an injury.
Who treats arthritis? Your primary care doctor is usually the first stop and can order X-rays and blood tests. Inflammatory types such as rheumatoid or psoriatic arthritis and gout that keeps coming back are managed by a rheumatologist, a doctor who specializes in arthritis and rheumatology. If you are searching for arthritis doctors near me, your insurer’s directory and a referral from your primary care doctor are the most reliable routes. Orthopedic surgeons and physical therapists join in for joint injections, surgery and rehabilitation.
Medical cannabis does not replace any of this. It cannot diagnose which type of arthritis you have, and it does not replace disease-modifying treatment for rheumatoid arthritis, which protects joints in a way no cannabis product has been shown to. Where cannabis can fit is as one possible add-on for symptoms, decided together with a doctor who knows your full picture.

Arthritis Pain Relief: Medication, Creams and Home Remedies
Before cannabis enters the conversation, it helps to see the standard toolkit. Most people with arthritis use several of these at once, and the right mix depends on the type of arthritis, the joints involved and your other health conditions.
Medicines
Acetaminophen (Tylenol) is often the first pill tried for osteoarthritis pain. NSAIDs such as ibuprofen and naproxen ease pain and inflammation, but can irritate the stomach and strain the kidneys and heart with long use. For rheumatoid and psoriatic arthritis, disease-modifying drugs (DMARDs such as methotrexate) and biologics prescribed by a rheumatologist slow the disease itself. Steroid injections can calm a single flaring joint.
Creams, heat and cold
An arthritis cream can help joints close to the skin, such as hands and knees. Options include anti-inflammatory gels like diclofenac, capsaicin (the “hot cream” made from chili peppers, which works best with regular use) and menthol rubs. Heat loosens stiff joints before activity; cold packs calm a swollen, flaring joint.
Movement and joint protection
Regular movement is one of the best-supported treatments for osteoarthritis. Arthritis exercises for seniors often start with walking, water exercise, cycling, tai chi and gentle strength work, ideally shaped by a physical therapist. Compression arthritis gloves, finger splints, thicker handles and golf grips, jar openers and a cane in the opposite hand all take load off sore joints.
Food and weight
No single list of arthritis-safe foods has been proven to stop arthritis. What is well supported: losing extra weight takes real load off knees and hips, and a Mediterranean-style diet plan rich in vegetables, fish and olive oil is a sensible base. For gout, cutting back on alcohol, sugary drinks and organ meats helps. Evidence for joint supplements and juices is mixed at best.
Medical cannabis is usually discussed as an addition to this toolkit, not a replacement for it, and mostly by people who still have pain despite the basics or who cannot take certain medicines. Whether it is worth trying, and in what form, is a decision to make with a doctor.
Which situation sounds like yours?
Exploring Cannabis for Arthritis Relief
The Endocannabinoid System: Your Body’s Natural Balance Keeper
The reason scientists look at cannabis for arthritis at all is a signaling network called the endocannabinoid system. Think of it as one of your body’s balance keepers: it helps tune pain signals, inflammation and immune activity in the brain, the nerves and the tissues around your joints. It has three parts: cannabinoids your body makes on its own (such as anandamide), receptors those messengers attach to (mainly CB1, concentrated in the brain and nerves, and CB2, found largely on immune cells), and enzymes that build and break the messengers down.
Cannabinoid receptors also sit on the cells that maintain cartilage and bone, and the system is active in the inflamed joint lining of people with osteoarthritis and rheumatoid arthritis. Plant cannabinoids such as THC (the compound that causes a “high”) and CBD (which does not) act on this network in different ways, which is why they are studied separately. That biology makes cannabis a reasonable thing to test. It does not, by itself, prove that cannabis relieves arthritis pain in people.
How Cannabis May Help with Arthritis Symptoms
The four ideas below are the ones people hear most often. Each carries a label showing what kind of evidence stands behind it, because “studies show” can mean a trial in people or a test in a dish.
Pain Relief
The most rigorous trial, in knee osteoarthritis, found oral CBD no better than placebo [1]. A small open-label study of a CBD skin gel for hand osteoarthritis reported lower pain scores, but without a placebo group [3], and patients in a UK registry reported improvements without any comparison group [4].
Reducing Inflammation
In animal and laboratory studies, cannabinoids lowered inflammatory messengers such as TNF-alpha and IL-6 and calmed inflamed joint tissue. Trials in people with osteoarthritis have not translated this into meaningful pain relief.
Protecting Joints
Lab work suggests cannabinoids acting on CB2 receptors might slow the enzymes that break down cartilage and influence the cells that remodel bone. No study in people has shown that cannabis slows joint damage or changes how arthritis progresses.
Improvement in Other Symptoms
Sleep, mood and opioid use come up often. After joint replacement, people who reported using cannabis were less likely to still be on opioids at 90 days than matched patients [5], but that study shows an association, not cause and effect. Better sleep and calmer mood are reported by users rather than proven in arthritis trials.
Low risk: skin reactions to CBD creams and gels
Products applied to the skin are the gentlest way cannabinoids are used, but not free of effects. Reviews of topical and transdermal CBD describe local skin redness in some users, and advise extra care if you have sensitive skin or contact dermatitis [6]. A cream also does not replace a conversation about your other medicines: transdermal patches and some gels are designed to reach the bloodstream.
What the Trials Actually Found
Research on cannabis and arthritis is uneven. Knee osteoarthritis has a well-run randomized trial; hand osteoarthritis has small early studies; rheumatoid arthritis has almost nothing in people. Pick your situation to see the strongest human evidence for it.
Which kind of arthritis do you have?
Your diagnosis is on your visit summary or in your patient portal. Not sure which type? Ask the clinic that diagnosed it.
Pick your type: this panel shows the strongest human study for it.
Knee osteoarthritis
No difference vs placebo
Oral CBD at 600 mg a day, the dose used in this study, was added to acetaminophen for 8 weeks. Pain scores improved no more than with placebo: the gap was 0.1 points, p=0.8 [1].
What this means for you: for knee pain, the best evidence says oral CBD alone is unlikely to make a noticeable difference. Forms, THC-containing products and other joints were not tested here.
Hand osteoarthritis
−1.9 points on a 0-10 pain scale [3]
A 4% transdermal CBD gel (about 30 mg of CBD a day) rubbed on the finger joints for 4 weeks lowered current pain by about 1.9 points [3]. Everyone knew they were using CBD, so part of that change may be expectation.
What this means for you: skin products for hand arthritis are promising enough to test properly, but a placebo-controlled trial has not confirmed the effect yet.
Rheumatoid arthritis
No controlled trial to cite yet
The evidence summarized here contains no controlled trial of cannabis for rheumatoid arthritis pain. A 2026 survey of people with arthritis found that 27% had used cannabis in the past three months [7], which shows how common use is, not whether it works.
What this means for you: results from knee osteoarthritis do not carry over to RA. Keep your disease-modifying treatment and raise cannabis with your rheumatologist as a question about symptoms.
After knee replacement
No clear difference in repeat procedures
People with a diagnosed cannabis use disorder needed a manipulation of the new knee under anesthesia within a year about as often as people who used neither cannabis nor opioids: 0.69 times as often, with a likely range of 0.32 to 1.47 [8].
What this means for you: this study looked at safety after surgery, not pain relief. A trial of CBD for lasting pain after knee replacement is now being set up [9].
Every Human Study at a Glance
The table lists the studies in people, from the strongest design to the weakest. Animal and laboratory work is left out on purpose: it explains how cannabis might act, not whether it helps you.
| Study (type, year) | Who took part | What was tested | What happened | Source |
|---|---|---|---|---|
| Osteoarthritis | ||||
| Randomized placebo-controlled trial, 2023 | 86 people with painful knee osteoarthritis (58 finished) | Oral CBD 600 mg a day plus acetaminophen, 8 weeks | No difference in pain from placebo; more side effects and a rise in liver enzymes | [1] |
| Systematic review and meta-analysis, 2026 | Pooled human and animal studies of osteoarthritis | Cannabis extracts vs placebo | In people, no clear difference in pain (wide, uncertain range) | [10] |
| Randomized trial of a supplement, 2023 | 38 people with knee osteoarthritis | Hemp seed oil with beta-caryophyllene, myrcene and ginger (a supplement, not a THC or CBD product), 45 days | Pain and function scores improved more than in the comparison group; no placebo, short follow-up | [11] |
| Open-label trial, 2024 | 15 people with hand osteoarthritis | 4% transdermal CBD gel, 4 weeks | Pain fell by about 1.9 points out of 10; no placebo group | [3] |
| Registry study (observational), 2024 | 77 UK patients with osteoarthritis | Prescribed cannabis-based medicines | Patients reported improvements; no comparison group | [4] |
| Chronic pain treated with opioids | ||||
| Crossover randomized placebo-controlled trial, 2023 | 37 adults with chronic pain, average age 62 | Dronabinol (synthetic THC) 10 mg with hydromorphone 4 mg | No extra pain relief; more moderate side effects and stronger “high” ratings | [12] |
| After joint replacement | ||||
| Cohort study, 2022 | Knee replacement patients with cannabis use disorder | Repeat procedures vs people without cannabis or opioid use | No clear difference in manipulation or revision surgery | [8] |
| Case-control study, 2022 | Hip and knee replacement patients | Self-reported cannabis use vs matched patients | Less persistent opioid use at 90 days (an association, not proof of cause) | [5] |
| Arthritis in general, including rheumatoid arthritis | ||||
| Cross-sectional survey, 2026 | 283 people with arthritis | How many use cannabis and how they rate their quality of life | 27% used cannabis in the past three months; the design cannot show cause and effect | [7] |
How Big Is the Effect?
“Helps” and “does not help” hide the real question: by how much, compared with what? Here are the three pain numbers from human osteoarthritis studies, then a chart of the one study that reports several estimates with a likely range.
After knee replacement, did people with cannabis use disorder need more repeat procedures?
How to read this: each dot is the study’s best estimate, the bar around it is the likely range (95% confidence interval), and the vertical line marks “no difference”. A dot left of the line means fewer repeat procedures; right of it means more. A hollow dot means the range crosses the line, so the study cannot tell the groups apart.
Manipulation of the knee under anesthesia within 1 year, compared with no cannabis or opioid use [8]
no clear difference, 0.69× (0.32-1.47) [8]
Show as a table
| Outcome | Compared with | Odds ratio (95% CI) | p |
|---|---|---|---|
| Manipulation under anesthesia, 1 year | No cannabis or opioid use | 0.69 (0.32-1.47) [8] | 0.34 [8] |
| Revision surgery, 2 years | No cannabis or opioid use | 1.07 (0.50-2.27) [8] | 0.848 [8] |
| Manipulation under anesthesia, 1 year | Opioid use | 0.91 (0.41-2.05) [8] | 0.837 [8] |
Put together, the picture is consistent. Where cannabis has been tested carefully against a placebo in osteoarthritis, the pain benefit has been small or absent. Where results look better, the studies were open-label or had no comparison group, which tends to make any treatment look stronger than it is.
What Science Doesn’t Know Yet
The honest list of open questions is long, and it matters for your decision as much as the results do.
- Small studies. Several trials enrolled only a few dozen people or fewer, too few to detect modest benefits or rare harms.
- Missing placebo groups. The more encouraging studies were open-label or lacked a control group, so expectation and natural ups and downs of pain may explain part of the change.
- One dose, one product. Most trials tested a single fixed dose of one compound, so nobody knows whether a different dose, a THC:CBD combination or whole-plant products would act differently.
- Almost nothing in rheumatoid arthritis. Findings in knee osteoarthritis do not transfer to an autoimmune disease, and controlled human data in RA are missing.
- No proof of joint protection. The idea that cannabinoids slow cartilage loss comes from the lab; no human study has measured it.
- Topicals without standards. Creams, gels and patches vary widely in strength and formula, and there is no agreed dosing for products applied to the skin.
The Future of Arthritis Treatment and Cannabis
Research is moving toward questions that matter to patients. A randomized pilot trial is testing whether CBD reduces persistent pain after total knee replacement [9]. Other groups are refining skin gels and patches that act locally on a joint, comparing THC:CBD ratios rather than single compounds, and developing drugs aimed at the CB2 receptor, which may avoid the “high” that comes with THC. None of this guarantees a future treatment; it means the answers should get clearer over the next few years.
Ways to Use Cannabis: What’s Right for You?
Cannabis is not the same thing as smoking. People with arthritis use creams, oils, capsules and edibles at least as much as anything inhaled, and each route enters the body differently. The table shows what each form avoids and what still applies to it. It does not rank them: choosing a form is a conversation with your doctor, not something this page can decide for you.
| Form | How it enters the body | What it avoids | What still applies |
|---|---|---|---|
| Smoking: joints, blunts, pipes, bongs | Smoke from burning plant material is inhaled into the lungs | The delayed start of swallowed products | Smoke irritates the airways; THC effects, drowsiness, impaired driving and drug interactions |
| Vaping: dry-herb vaporizers, oil cartridges and pens; dabbing concentrates | Heated vapor or aerosol is inhaled without burning | Combustion smoke | Hot aerosol still passes through the airways; concentrates can be very strong; THC effects and interactions |
| Edibles, beverages, capsules | Swallowed, absorbed through the gut and processed by the liver before reaching the blood | Smoke and vapor in the airways | Effects start later and last longer; liver processing and drug interactions; THC effects |
| Tinctures and oils under the tongue, mouth sprays | Partly absorbed through the lining of the mouth, partly swallowed | Smoke and vapor in the airways | The swallowed part goes through the liver; drug interactions; THC effects if it contains THC |
| Topicals: creams, balms, ointments | Applied over a joint for a local effect in the skin and tissue beneath | Airways and, for most products, a meaningful amount in the blood | Possible skin redness or irritation; strength and formulas are not standardized |
| Transdermal patches and gels | Designed to pass through the skin into the bloodstream | Airways and first-pass processing in the liver | Reaches the whole body, so drowsiness and interactions still apply; skin reactions |
| Suppositories (rectal or vaginal) | Absorbed through the lining of the rectum or vagina; rarely used | Airways | Little research; whole-body effects and interactions |
| Prescription medicines, not dispensary products | |||
| Dronabinol (Marinol, Syndros), nabilone (Cesamet), cannabidiol (Epidiolex) | FDA-approved capsules or oral solutions, prescribed by a doctor and filled at a pharmacy | Variable dispensary labeling | Approved for other conditions, not arthritis; side effects and interactions as with any medicine |
A second question sits on top of the form: what is in the product. THC and CBD behave differently, and a risk or benefit seen with one does not automatically apply to the other or to a product that mixes them.
Moderate risk: edibles act late and last long
A gummy, chocolate or capsule can take a long time to take effect and then last for hours. Taking a second dose because “the first one didn’t work” is one of the most common reasons people end up with far more THC than they intended: dizziness, a racing heart, anxiety and, in older adults, falls. Anything swallowed also passes through the liver, where it can interact with other medicines.
Choosing the Right Product and Dosing Principles
Dispensary shelves can feel overwhelming: dozens of strains, ratios and formats, each with confident labels. A few principles make the choice easier to discuss with a clinician.
Cannabinoid Types
THC causes the “high” and is the compound most linked to drowsiness, dizziness and impaired coordination. CBD does not cause a high but is processed by the liver and was linked to raised liver enzymes in the knee trial [1]. Products are labeled by their THC:CBD ratio. The result of a CBD trial says nothing about a THC product, and the reverse is also true.
Strains and Profiles
“Indica”, “sativa” and “hybrid” labels are popular, but there is very little evidence that they reliably predict how a product will affect arthritis pain. Terpenes such as beta-caryophyllene and myrcene have been studied in knee osteoarthritis only as part of a supplement combined with hemp seed oil and ginger [11], so the result cannot be credited to cannabis itself.
Dosing
The guiding rule is “start low, go slow”: begin with a very small amount, wait long enough to judge the effect (especially with edibles) and increase only gradually. Doses in research are a reference point, not a recommendation for you. In a UK registry of people with osteoarthritis, the median daily doses recorded were 25.5 mg of CBD and 105 mg of THC [4].
Finding a dose is something to do with a doctor who knows your other medicines, your liver and kidney health and whether you drive or care for others. A clinician can also help you keep a simple log of dose, time, pain and side effects, which turns trial and error into an actual answer.
Side Effects: What the Studies Reported
Caution with Side Effects
Side effects depend heavily on what is in the product and how it is taken. THC is the main source of dizziness, dry mouth, lightheadedness, a “high”, slower reactions and problems with memory and concentration, and these grow with the dose. CBD rarely causes a high, but in the knee trial it was not side-effect free.
Liver enzymes rose
People taking 600 mg of oral CBD a day had higher liver enzyme levels (ASAT, ALAT and gamma-GT) than people on placebo, p=0.02, and more side effects overall, p=0.008 [1]. The researchers advise checking liver tests when starting CBD.
Important Considerations and Potential Side Effects
Across the human studies, these are the effects reported most often:
- Stomach and gut: diarrhea, abdominal pain and stomach discomfort with oral CBD and products used in the mouth [1][6].
- Tiredness and dizziness: fatigue with oral CBD, and dizziness with mouth sprays [1][6].
- Skin: redness where a transdermal product was applied [6].
- Stronger effects when combined with opioids: more moderate side effects and higher “high” ratings when dronabinol was added to hydromorphone [12].
Three practical risks matter as much as anything in a trial. Do not drive or operate machinery after using THC: it slows reaction time and coordination, and many states treat impaired driving the same way whatever the substance. Drowsiness and dizziness raise the risk of falls, which is a real concern for older adults with stiff knees or hips. And THC-dominant products carry some risk of misuse and dependence, which is worth naming honestly with your doctor if you or your family have a history of substance problems.
Before you start: who should avoid cannabis and which medicines don’t mix
Does Arthritis Qualify for a Medical Marijuana Card?
In many states, yes, but how depends on where you live. Every state with a medical cannabis program writes its own list of qualifying conditions, and arthritis reaches that list in one of two ways.
Arthritis named on the state list
Some states list arthritis, or a specific type such as rheumatoid arthritis, as a qualifying condition by name. If your diagnosis matches, the doctor confirms it and documents how it affects you.
Through chronic pain or a doctor’s judgment
Other states do not name arthritis but accept chronic or severe pain, or let a licensed physician recommend cannabis for any condition they judge it may help. Long-lasting arthritis pain often qualifies this way.
Looking for a medical card for rheumatoid arthritis specifically? RA usually qualifies through the same two routes: by name where a state lists it, or through chronic pain. Because RA is an autoimmune disease, the doctor will also want to know which disease-modifying treatment you take and who manages it. That is not a hurdle; it is part of making sure cannabis would sit safely alongside your treatment.
You can browse all qualifying conditions we cover and read the medical cannabis rules in each state. The quickest way to know for certain is the evaluation itself: a doctor licensed in your state checks your diagnosis against that state’s rules.
About Medical Marijuana Programs: Where to Buy and How Dispensaries Work
A doctor’s recommendation is the first half of the process. The second is your state’s medical cannabis program: you register with the state registry, pay the state’s own fee where there is one and receive a patient card or registry number. That card is what a medical dispensary checks at the door, and it is what separates you, legally, from someone buying without one.
Where You Can Buy
Medical dispensary
Serves registered patients. Staff can talk through forms, ratios and labels, and the range often includes topicals, tinctures, capsules and other non-inhaled products that people with sore hands and knees ask about.
Recreational store
Open to adults over the legal age in states with adult-use laws. Products overlap with medical ones, but staff are retailers rather than patient advisors, and purchases are taxed and limited as recreational sales.
Hemp shop: CBD and delta-8
CBD creams, oils and delta-8 THC products sold in shops, gas stations and online are made from hemp and sit outside state medical programs. Their strength and purity are not checked the way dispensary products are, and delta-8 still causes a high. They are not the same as medical cannabis, even when the packaging looks clinical.
What Changes From State to State
Four things vary the most between states, and they decide what a card actually gives you: whether cannabis is legal for medical use only or for adults as well; how much a registered patient may buy and possess; how medical purchases are taxed compared with recreational ones; and whether patients may grow a limited number of plants at home. Many state programs also let a patient designate a registered caregiver who can buy on their behalf, under rules set by that state. The current numbers for your state are on our state laws and regulations pages.
Medical Card vs. Recreational Purchase: What’s the Difference?
In a state where adults can already buy cannabis, a medical card can still matter. Depending on the state, patients may:
- pay lower taxes on purchases than recreational customers;
- buy and possess larger amounts than adult-use limits allow;
- qualify from a younger age than the recreational minimum;
- reach medical dispensaries with a wider range of products and staff who discuss them with patients;
- have certain legal protections that only apply to registered patients.
In medical-only states, there is no legal way to buy at a dispensary without a card at all. How much a card saves you depends on your state’s tax rules and how much you buy; our state pages explain the rules where you live.
Traveling? Some states honor out-of-state cards or offer visitor registration and many do not, so check the rules of the state you are visiting before you go. Cannabis remains illegal under federal law, so never carry it across state lines or onto a plane.

Talking to Your Doctor About Medical Cannabis: A Mini-Guide
Bringing up cannabis with a doctor can feel awkward, especially if you expect a lecture. Most clinicians would much rather know than guess, because cannabis affects drug interactions, liver tests and anesthesia. A little preparation turns it into an ordinary medical conversation.
- Be prepared. Note your pain on a 0 to 10 scale over a typical week, your stiffness, your sleep and the tasks arthritis gets in the way of.
- Be open. Say why you are interested, what you have tried, including any cannabis or CBD in the past, and what you hope for.
- Ask about forms and doses. Which form would avoid your particular risks, what THC:CBD balance makes sense, and how to start low and adjust.
- Decide together. Agree how you will judge whether it is working and when you will review it, so it does not drift on without a plan.

Frequently Asked Questions About Arthritis and Cannabis
Does cannabis help arthritis pain?
The evidence is mixed. In the strongest trial, oral CBD was no better than placebo for knee osteoarthritis pain [1]. Smaller open-label studies, such as a CBD skin gel for hand arthritis, reported lower pain without a placebo comparison [3]. Some people do report relief, and whether it is worth trying for you is a decision to make with a doctor.
Is CBD cream good for arthritis?
It is one of the gentler options, and an early study of a transdermal CBD gel for hand osteoarthritis was encouraging, but it had no placebo group [3]. Skin products vary widely in strength, can cause redness, and transdermal versions reach the bloodstream [6]. Treat a CBD cream as an experiment to discuss with your doctor, not a proven treatment.
Does arthritis qualify for a medical card?
In many states it does, either named on the list of qualifying conditions or through chronic pain or a physician’s judgment. The evaluation is a telemedicine appointment: a doctor licensed in your state reviews your history online and decides under that state’s rules, with nowhere to travel. See how arthritis qualifies and the rules in each state.
Can I use cannabis with Tylenol or NSAIDs?
Ask your doctor first. In the knee trial, CBD was taken together with acetaminophen (Tylenol), and liver enzymes rose more than with placebo [1]. Cannabinoids can also slow the liver enzymes that clear many medicines. Your doctor may want liver tests and may adjust timing or doses. See medicines that don’t mix.
Does arthritis pain come and go?
Yes. Both osteoarthritis and rheumatoid arthritis tend to flare and settle. Overuse, poor sleep, stress, weather changes and, in RA, disease activity can all trigger a flare. Keeping a simple pain diary helps you and your doctor see patterns and judge whether any treatment, cannabis included, is really making a difference.
Why is arthritis worse when it rains?
Many people feel more pain in cold, damp weather or when the air pressure drops. The exact cause is still debated: possible explanations include tissues around the joint reacting to pressure changes, stiffer muscles in the cold and simply moving less on bad-weather days. Warmth, gentle movement and layers often help.
Is delta-8 the same as medical cannabis?
No. Delta-8 THC products are usually made from hemp-derived CBD and sold outside state medical programs. They cause a high, and their strength and purity are not checked the way regulated dispensary products are. Medical cannabis is bought from licensed dispensaries by registered patients.
Can I buy at any dispensary?
With a valid patient card, you can buy at licensed medical dispensaries in your state. Recreational stores are open to adults only in states with adult-use laws, and your medical benefits may not apply there. Your state’s rules are on our laws and regulations pages.
Does my card work in other states?
Sometimes. Some states accept out-of-state cards or offer a visitor registration; many do not. Check the state you are visiting on our laws and regulations pages before you travel, and never carry cannabis across state lines or through an airport.
What if I lose my card or it expires?
A lost card is replaced through your state program, usually through its online patient portal. Cards and recommendations expire on a schedule each state sets, and renewal normally means a fresh evaluation with a doctor licensed in your state before the old one runs out. See our medical card FAQ.
Will a medical card affect my job or gun ownership?
It can. Cannabis is still illegal under federal law, and the federal firearms purchase form asks about marijuana use regardless of state law. Employment protections for patients differ widely by state, and safety-sensitive and federally regulated jobs usually follow federal rules. Your medical records stay private under HIPAA, and state registries are not public. Check the laws in your state and ask an attorney if your job or firearms are at stake.
Will cannabis get me high?
It depends on the THC content. THC causes a high; CBD-dominant products usually do not. Creams with a local effect are unlikely to, while edibles, tinctures and inhaled products containing THC will. Drugs aimed at the CB2 receptor, which might avoid the high, are still in research.
What if traditional treatments aren’t working for my arthritis?
First, ask whether your diagnosis and treatment plan still fit: inflammatory arthritis in particular may need a change of disease-modifying treatment. If pain persists despite good standard care, medical cannabis may be discussed as an add-on. A licensed doctor can help weigh it against your other options and medicines.

Similar Conditions and States for Medical Cannabis Consideration
Arthritis rarely travels alone. Long-lasting joint pain often brings poor sleep, muscle tension, worry and headaches, and each of these has its own page with its own research summary. State rules decide what you can do with any of them.
Key Takeaways for Patients
- The research is mixed, not magic. The best trial found oral CBD no better than placebo for knee osteoarthritis [1]; smaller open-label and observational studies are more positive but cannot rule out expectation. Rheumatoid arthritis has no controlled trial to rely on.
- Form changes some risks, not all. Smoke and vapor affect the airways; creams and patches avoid that. Any form that reaches the blood, whether swallowed, held under the tongue or absorbed through a patch, still brings THC effects, drowsiness and driving risk.
- Liver and medicines come first. Oral CBD raised liver enzymes in a trial [1], and cannabinoids can interact with pain relievers, gabapentin, opioids and sedatives. Bring your full medicine list to any evaluation.
- The next step is a doctor, not a dispensary. A licensed physician can check your diagnosis against your state’s rules, weigh the risks for you and, if appropriate, recommend medical cannabis as part of a wider plan.
Who Should Avoid Cannabis With Arthritis – and Medicines That Don’t Mix
High risk: groups who should avoid cannabis or use it only under close supervision
- Pregnancy and breastfeeding. Cannabis is generally advised against, and researchers exclude pregnant and nursing women from arthritis trials.
- Psychosis or serious mental illness. THC can worsen psychotic disorders and severe anxiety in people who are prone to them.
- Uncontrolled heart disease. THC can raise heart rate and affect blood pressure; trials exclude people with uncontrolled cardiovascular or severe heart and lung disease.
- Liver or kidney failure. Both change how cannabinoids are cleared and are standard reasons to exclude people from trials; oral CBD raised liver enzymes even in healthy livers [1].
- Older adults at risk of falls. Dizziness and drowsiness on top of stiff knees and hips can lead to falls and fractures.
- A history of substance use disorder. THC-dominant products carry a risk of misuse and dependence.
Tell your doctor about every medicine and supplement you take, and never combine cannabis with prescription pain relievers or sedatives without professional guidance.
Interactions with Other Medications
Cannabinoids are processed by the same liver enzymes that clear many common medicines, and THC adds to the effects of anything else that makes you drowsy. Open each card to see what has actually been observed and what kind of evidence it is.
Opioids (for example hydromorphone)Clinical study
In a randomized placebo-controlled crossover trial, adding dronabinol (synthetic THC, 10 mg) to hydromorphone (4 mg) gave no extra pain relief but caused more moderate side effects and stronger “high” ratings [12]. The authors advise against combining them for pain.
Acetaminophen (Tylenol)Clinical study
In the knee osteoarthritis trial, everyone took acetaminophen 3 g a day; those who also took oral CBD had a larger rise in liver enzymes than those on placebo, p=0.02 [1]. Both are processed by the liver, so ask about liver tests if you plan to combine them.
NSAIDs (ibuprofen, naproxen, meloxicam)Pharmacokinetic
Cannabinoids may slow the liver’s cytochrome P450 enzymes in a dose-dependent way, which can make other medicines linger longer. The observations come from dogs with osteoarthritis given CBD alongside NSAIDs, in whom a liver marker (ALP) rose [13]. Human data are lacking, so treat this as a reason for caution, not a measured risk.
Gabapentin and pregabalinMechanism only
Gabapentin and THC both cause drowsiness and dizziness, so together they may add up. Possible effects on how CBD and gabapentin are processed have been described only in dogs [13]. Tell your doctor before combining them, especially if you are older or drive.
Alcohol, sleeping pills and other sedativesClinical report
Sleepiness increased when transdermal CBD was used together with clobazam, a sedating medicine [6]. Alcohol, benzodiazepines, sleeping pills and some muscle relaxants all add to cannabis-related drowsiness, slower reactions and fall risk.
Take the next step with a licensed doctor
Fill out a short form in about 5 minutes, then see a doctor licensed in your state for about 15 minutes, at a time you agree together. If the doctor approves, your recommendation can arrive in as little as 15 minutes after the appointment, depending on your state. Nobody can promise that cannabis will ease your arthritis; a careful evaluation can tell you whether it is a reasonable thing to try.
