Can medicinal cannabis help with tourette syndrome in NZ?
Emerging evidence for tourette syndrome. Emerging evidence from small adult trials showing a tic-reduction signal — but the data are adult-only and do not generalise to children.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
Small adult RCTs show a fairly consistent tic-reduction signal (THC appears to be the active component), but samples are very small and a recent pilot RCT missed its primary tic outcome. Importantly, the data are in adults, not the children and adolescents in whom Tourette syndrome most often presents, so they do not generalise to younger patients.
Cannabinoids studied
- THC
- Balanced THC:CBD
Key cautions
- Evidence is adult-only and does not generalise to children.
- THC cognitive and psychiatric effects.
- Caution given common ADHD/OCD/anxiety comorbidities; trials are small and heterogeneous.
