The evidence that CBD helps with pain is weak. A 2024 review found 15 of 16 placebo-controlled trials showed no benefit over a dummy treatment, and NICE doesn’t recommend CBD for chronic pain outside research. A few small trials of CBD applied to the skin were more positive. Many people still use CBD as part of a wider routine.
Below: what the trials found, oral vs topical CBD, how people use it, dose, safety, and what has better evidence for pain.
Does CBD help with pain? The research
| Source | What it found |
|---|---|
| Review of CBD pain trials, 2024 | 16 randomised trials across 12 types of pain, at 6mg to 1,600mg. 15 found no benefit over placebo |
| Hand arthritis trial, 2022 (129 people, Denmark) | 20 to 30mg a day for 12 weeks: no difference from placebo |
| Acute back pain trial, 2021 (100 people, Australia) | A single 400mg dose in A&E was no better than placebo |
| Topical CBD for nerve pain, 2020 (29 people, USA) | CBD oil on the skin reduced sharp and intense pain compared with placebo over 4 weeks |
| NICE guidance (UK) | Do not offer CBD to manage chronic pain in adults unless as part of a clinical trial |
Many of the positive results people quote come from animal studies, or from products combining CBD with THC, which is a different thing. Sativex, a THC and CBD spray, is licensed in the UK only for muscle spasticity in MS. Over-the-counter CBD contains no meaningful THC, so those results don’t carry over.

| Type | CBD evidence | Read more |
|---|---|---|
| Arthritis and joints | The best-designed oral trial found no benefit | CBD for joint pain |
| Back pain and sciatica | No benefit in the one emergency trial | CBD for sciatica |
| Muscle soreness | Small, mixed sports studies | CBD for muscle recovery |
| Nerve pain | One small positive topical trial | CBD balm guide |
| Migraine | No good CBD-only trials | CBD for migraines |
| Fibromyalgia | No benefit shown for CBD alone | CBD for fibromyalgia |
Oral vs topical CBD
| Oil or capsules | Balm or cream | |
|---|---|---|
| How it’s used | Under the tongue or swallowed | Massaged into one area |
| Reaches | The whole body via the bloodstream | Mainly the skin and area applied |
| Evidence for pain | Mostly no benefit in trials | Limited, but the few small trials are more positive |
| Interactions | Can interact with medicines | Very little reaches the blood |
With a balm, the massage itself, warmth and ingredients like menthol may account for some of the feeling of relief. See CBD balm vs Tiger Balm.
How people use CBD
People living with aches often use CBD as one part of a wider routine rather than a painkiller: a balm massaged in after exercise, or a few drops of oil in the evening as part of winding down. Pain and poor sleep often go together, and many people use CBD in the evening for that reason. See CBD for sleep.
If you try it, keep a simple diary of your pain and sleep for three to four weeks so you can judge honestly whether it’s worth continuing. Choosing a product? See our buyer’s guide to CBD oil for pain.
How much CBD, and how long?
There’s no proven dose for pain. Trials have used anything from 6mg to 1,600mg a day without clear benefit, and the higher doses bring more side effects. Start low, increase slowly, and give it a few weeks. See how much CBD to take.
The FSA’s 10mg a day figure is precautionary advice rather than a legal limit, set while longer-term safety research continues. At Evopure we think it is a very cautious figure, and many adults use more. If you go above it, increase slowly, and check with your GP or pharmacist first if you take any medication.
Safety and medicines
- Painkillers and other medicines: CBD can change how some medicines are processed, including some blood thinners, epilepsy medicines and opioids. Ask a pharmacist first. See CBD and medication.
- Liver: high oral doses can raise liver enzymes. See is CBD bad for your liver?
- Don’t stop prescribed painkillers or change your dose without talking to your GP.
- Pregnancy and breastfeeding: we don’t recommend our products during pregnancy or breastfeeding.
iSee your GP if pain is new, severe, getting worse, or comes with numbness, weakness, fever or weight loss.
What has better evidence for pain
Chronic pain affects between a third and a half of UK adults. For long-term pain, NICE recommends:
- Exercise and staying active, often through a physiotherapist-led programme.
- Psychological therapies such as CBT or acceptance and commitment therapy, which help with the impact of pain.
- Acupuncture, for some types of chronic pain.
- Prescribed medicines, chosen with your GP for the type of pain.
