What do you mean by mediterranean diet? What non-medication pain relief is effective for arthritis? Is cannabis effective for arthritis pain?

The short version: the strongest non-drug option for arthritis pain is exercise, not cannabis or diet. Cannabis has reported symptom relief but the trials are small, short, and mostly not placebo-controlled.

The evidence we have separates clearly. Exercise — strength training, walking programs, Tai Chi, aquatic exercise — has the best track record across many trials. A 2024 systematic review of four trials with 1,317 participants found that elastic band therapy, Wuqinxi, and Tai Chi all reduced pain and improved function in knee osteoarthritis [4]. A 2011 meta-analysis of 12 studies showed exercise gave small-to-moderate pain relief, with effect sizes running from 0.11 to 1.06 depending on the program [3]. One study in women found Baduanjin, a traditional exercise, reduced pain scores by 62% over six weeks while the control group got worse [2]. Another study with 22,588 patients in the GLA:D program found everyone improved by about 12-14 points on a 100-point pain scale at 3 and 12 months [5]. The research is dominated by knee osteoarthritis, but the principle — movement reduces pain — is consistent. None of these trials were funded by a manufacturer selling a product. The effect is real, though modest for some exercise types.

The Mediterranean diet is harder to judge from the records here. One systematic review evaluated Mediterranean diet interventions outside the Mediterranean region and listed rheumatoid arthritis among the health conditions studied but gave no specific effect sizes for arthritis pain [1]. A 2011 review of complementary and alternative medicines for rheumatoid arthritis examined dozens of compounds — borage seed oil, thunder god vine, rose hip, evening primrose oil, willow bark, vitamin E — and found only borage and thunder god vine showed potential in small trials; most others showed no consistent benefit [10]. None of this is about a dietary pattern as such. You were told about weight reduction before, and that is still real, but the evidence in these records for the Mediterranean diet specifically on arthritis pain is very thin.

Cannabis has user-reported relief but almost no controlled trial data. In a 2024 survey of 629 adults referred for chronic musculoskeletal pain, about 23% had used cannabis for pain and most who used reported relief [7]. The people who used cannabis were younger (51 versus 57), had more pain areas (3.8 versus 3.0), and were much more likely to have used recreational cannabis before (50% versus 4.7%) [7]. In a 2002 case series of 15 people with chronic pain including two with rheumatoid arthritis, 12 of 15 reported pain improvement, but that study had no control group [8]. An observational study from 2022 in Australia studied 151 people taking oral 1:1 THC:CBD oil for chronic refractory pain; about 60% reported at least one adverse event (dizziness, nausea, dry mouth), though none were classified as serious [9]. Pain impact improved by a modest 2.3 points for about 48% of people, but the mean change did not reach the trial's own threshold for meaningful improvement. The funding source for the Australian study was the manufacturer (LGP Classic, a brand of cannabinoid oil) [9].

It is worth noting that cossabis is still a drug with its own risk profile — the ultra-rapid metabolizer PTSD, use dropped 0.28 times in states where recreational cannabis was legalized [6]. But the evidence for cannabis at sites of skeletal pain is still in the anecdotal stage: providers report symptoms, the published data is from small, open-label, or uncontrolled studies. The exercise evidence has been replicated over decades.

My call: start with exercise of any kind you will actually do. The Mediterranean diet is healthy but not proven to relieve arthritis pain from these records. Cannabis has marginal evidence, side effects are common, and the controlled data is thin. Confidence: moderate.
