Arthritis is a common condition that affects hundreds of millions of people around the world, and in the UK, with a particular tendency in older adults. It is one of the common causes of reduced mobility and chronic pain in older people. Conventional pharmaceuticals absolutely help manage pain and other symptoms, especially early on, but long-term patients can report diminishing returns and increasing side effects.
Medical cannabis is an increasingly popular alternative for arthritis patients, where it is legal for prescription. But what does the science and the evidence actually say?
What is Arthritis and How Can Cannabis Help?
Arthritis is not one single condition. It is, in fact, a catch-all term for various related conditions that cause pain and inflammation in joints. Osteoarthritis is the most common form in the UK and worldwide. Rheumatoid arthritis, an autoimmune condition, is not as common but still affects significant numbers of people.
The joints most often affected by arthritis are:
- wrists
- knuckles
- spine
- knees
- hips
- shoulders
There is no cure for osteoarthritis. The condition is not necessarily degenerative (gets worse over time), and lifestyle factors can play a part. Nevertheless, it leaves many previously healthy patients with chronic pain as they age. Up to 80% of people with other osteoarthritis symptoms develop long-term pain, according to averages of many studies.
Today, millions of people across legal markets around the world, like the US, Canada, Germany, and the UK, are discovering relief through medical cannabis for arthritis pains. One in five medical cannabis prescriptions in the UK are for arthritis or related symptoms.
While cannabis is not a cure for arthritis, it is showing increasing promise as an alternative to pharmaceutical pain medications in cases of chronic pain. Which is the symptom most commonly presented by people with the condition? According to one recent UK study, 95% of patients with chronic pain who started prescribed medical cannabis treatment saw improvements to their quality of life.
The Science Behind Medical Cannabis for Arthritis Symptoms
Cannabis is, at this point, certified for its painkilling properties. It has been used medicinally for thousands of years, but modern science is only just catching up to what human cultures have known for a long time.
Today, science understands that the main two compounds in cannabis, the cannabinoids THC and CBD, interact with the body’s own endocannabinoid system or ECS. The ECS modulates various hormones that stimulate different effects and bodily functions. THC and CBD work differently with the ECS, and varying levels of the compounds can have different medical effects.
CBD is of specific interest to patients with arthritis because of its anti-inflammatory properties. With fewer legal requirements to research CBD internationally, more clinical studies have been conducted in this field than with THC – and the results are promising. Some studies have shown that ingested CBD may promote extra intercellular calcium growth, which contributes to stronger bones.
THC is the main psychoactive component of cannabis and the one that seems to be most of use as a painkiller. Although not as blunt force effective in on-off situations at blocking pain, medical cannabis’ long-term holistic effects on pain management and sleep are consistently self-reported by new patients across the board.
Many patients with arthritis, mostly those presenting with chronic pain, report seeing meaningful relief from medical cannabis. However, it remains, or at least THC, a psychoactive medicine. And therefore it won’t be ideal for everyone. Patient-reported data is building up, but clinical studies are in short supply globally. Some of them do dispute the efficacy of medical cannabis, but data from real-world research is remarkably clear.
How Medical Cannabis Works in the UK Today
To obtain medical cannabis treatment for arthritis treatment in the UK, patients must go through private clinics. Due to the aforementioned relative lack of clinical study, as well as various other factors, the NHS’s medicines regulator, the National Institute for Health and Care Excellence (NICE), has so far refused to license it for general prescription under the national healthcare provider.
Nevertheless, it remains legal to prescribe. So private healthcare practices have stepped in. In 2026, it is estimated that some 75,000 people are current medical cannabis patients in the UK, with that number set to grow over the year. To qualify, patients must have:
- A diagnosed condition – or symptoms of another condition – listed by clinics
- Tried at least one or usually two other treatments that weren’t effective or satisfactory
- No record or family history of psychosis or schizophrenia
Licensed clinicians will guide you through the qualifying process, organise a treatment plan, and then complete the prescription. The medical cannabis medication will be sent to your door for you start treatment.
Prospective patients may be confused by the number of private clinic options available. Which is where comparison sites with, for example, Mamedica reviews, come in. Here, people can learn from the experts and other patients about which clinic is the most suited to their needs.
Note that medical cannabis is not to be smoked, as that remains illegal. Even with a prescription. Patients will usually start with cannabis oils or capsules, but they can request dried cannabis flower – for vaping only. Patients must keep their medication in the prescribed packaging, alongside proof of prescription if carrying it out and about.
After treatment begins, clinicians are required to have follow-up consultations with patients to monitor ongoing treatment for any issues or concerns. You may even be contacted for a national survey of patients, meaning you contributed to scientific research in the field.
