THC, tetrahydrocannabinol, the substance responsible for the psychoactive effects for marijuana we associate with getting high, comes with side effects such as reduced short-term memory, impaired thinking and potential anxiety, while CBD, cannabidiol, possesses therapeutic effects such as relief of pain, stress, depression, Alzheimer’s, epilepsy, as well as protecting those parts of the brain associated with memory and learning. CBD's positive effects are due to its ability to bond with receptors in the brain, hence the anti-anxiety, anti-spasmodic and neuroprotective effects, as well as receptors throughout the body, lending itself to anti-inflammation and pain relief.
As with a fermented food like kombucha, slight natural variations are normal and to be expected in a product such as CBD oil because it is made from living plants. Changes in the weather, soil, and water can all impact the biology of the source material. While we verify Certificates of Analysis (and take many other criteria into consideration during our review process), even the most reputable five-star companies have no way to control for every variable in this organic process.
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.
