CBD and arthritis: why people try it

Arthritis pain can make joints stiff, sore and harder to use. That is why CBD is often marketed as a natural option for people with osteoarthritis or rheumatoid arthritis. Cannabidiol does not produce the intoxicating high associated with THC, and some patients hope it may help with pain, sleep or inflammation.

The honest answer is that the evidence is interesting, but it is still not strong enough to call CBD a proven arthritis treatment.

What the studies show

Evidence typeWhat it suggests
Laboratory and animal studiesCBD and other cannabinoids may influence inflammatory pathways and pain signalling.
Small human studiesSome trials and observational reports suggest pain relief in osteoarthritis and rheumatoid arthritis, but results are mixed.
Systematic reviewsReviews have repeatedly said there is not enough high-quality evidence for routine clinical use in arthritis.

A 2024 systematic review of rheumatological disease research found a handful of studies with pain improvement, including osteoarthritis and rheumatoid arthritis. A separate rapid review focused specifically on arthritis reached a more cautious conclusion: there is still not enough evidence to recommend cannabis-based medicines for routine use.

What remains unclear

  • Which type of arthritis benefits most: osteoarthritis, rheumatoid arthritis and other inflammatory conditions do not behave the same way.
  • Whether CBD alone is enough: some products also contain THC, which makes it harder to know what is doing the work.
  • The best dose: studies use different formats and strengths, so there is no agreed arthritis dose.
  • Long-term use: the data on months or years of use is still limited.

What UK guidance says

The NHS says there is some evidence medical cannabis can help certain kinds of pain, but the evidence is not strong enough to recommend it for pain relief. NICE’s cannabis-based medicinal products guideline covers chronic pain, but that is not the same as endorsing CBD as a standard arthritis treatment.

In practice, that means CBD may be something people discuss with a clinician when standard treatment has not helped enough, but it should not be treated as a first-line or replacement therapy for arthritis.

Safety and quality issues

  • Product quality varies: the NHS warns that many CBD products sold online may be illegal to possess or supply, and some can contain THC.
  • Interactions matter: CBD and THC can affect how other medicines work, so check with a specialist if you take regular medication.
  • Side effects can happen: sleepiness, dry mouth, appetite changes and stomach upset are among the effects people report most often.

If a product leaves you drowsy or affects your judgement, do not drive or operate machinery. If you already take prescribed medicine, speak to a pharmacist or doctor before adding CBD.

Bottom line

CBD may help some people with arthritis symptoms, but the current evidence is not strong enough to treat it as a reliable or routine therapy. If you want to try it, use a reputable product, start low, and talk to a clinician before mixing it with other medicines or replacing existing treatment.
