So far, by far the best medicinal relief I have found for my systems is a particular strain of cannabis flower called Harlequin — it contains an almost 3:1 ratio of CBD:THC, which is extremely rare and unique in the cannabis world. There are multiple studies you can find online showing the SYNERGISTIC effects of CBD combined with THC. When they are used together, they are much more medicinally effective than other one is on their own. Most cannabis strains today have zero CBD because growers realized everyone just loves their THC, but the Harlequin strain is a god send.
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.
