Hi Kim — I hope you have found some relief over the past three months since you posted. I am 27 and have already been through four foot surgeries for arthritis, and will be having my hip operated on next month. I’ve tried everything over the last 8 years since this all started, and deal with a lot of the same issues you described (very poor sleep, limited mobility, etc.).
Cannabidiol is currently a class B1 controlled drug in New Zealand under the Misuse of Drugs Act. It is also a prescription medicine under the Medicines Act. In 2017 the rules were changed so that anyone wanting to use it could go to the Health Ministry for approval. Prior to this, the only way to obtain a prescription was to seek the personal approval of the Minister of Health.
