Can medicinal cannabis help with ibd in NZ?
Limited evidence for ibd. Limited evidence: may improve symptoms and quality of life, but NOT objective inflammation. Must never replace disease-modifying therapy.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
Cochrane reviews found no firm conclusions; an updated meta-analysis suggests cannabis may improve symptoms and quality of life but NOT objective inflammation or mucosal healing. This distinction is critical: it must be used only as an adjunct to standard disease-modifying therapy, never as a substitute, because symptomatic masking could delay treatment of active disease.
Cannabinoids studied
- THC
- Balanced THC:CBD
Key cautions
- Must NOT replace anti-inflammatory or immunomodulatory therapy — masking symptoms can delay treatment of active disease.
- Smoking cannabis is inadvisable in IBD.
- THC side effects and dependence risk.
