Can medicinal cannabis help with nerve pain in NZ?
Limited evidence for nerve pain. Limited, low-quality evidence with a striking harm signal — reserved behind standard nerve-pain medicines.There is no fixed list of qualifying conditions in NZ — whether it's appropriate for you is a clinical judgement for a registered doctor. This is education, not a treatment recommendation.
What the evidence says
A Cochrane review found 30% pain relief in 39% of patients vs 33% on placebo (number-needed-to-benefit 11), but a striking harm signal: nervous-system adverse events in 61% vs 29% (number-needed-to-harm just 3). Cochrane concluded the benefits 'might be outweighed by harms'. The IASP does not endorse routine use, and NICE recommends against it outside trials. It sits behind gabapentinoids, duloxetine and amitriptyline.
Cannabinoids studied
- Balanced THC:CBD
Key cautions
- High nervous-system adverse-event rate (number-needed-to-harm 3).
- Elevated psychiatric adverse events.
- Benefit may not exceed harm; CBD-alone evidence is insufficient.
