Cannabidiol, or CBD for short, is a phyto-cannabinoid found in cannabis plants. However, it does not cause the same psychoactive effects as other naturally occurring cannabinoids (such as tetrahydrocannabinol, or THC). CBD induces feelings of sleepiness and tranquility, making it suitable for insomnia and other sleep disorders; CBD can be used to alleviate symptoms of epilepsy, diabetes, and anxiety disorders, as well. Legality is an issue for some; all 50 states have laws governing the sale, possession, and use of CBD, and they vary significantly (see the table below for a full analysis).
Cannabis, on the other hand, was grown for many generations for medical and recreational purposes, so the genetic aspects of the plant that have survived and evolved are different. The cannabinoids, terpenes, and strength of the different parts of the plant have been bred to induce different effects in people or help solve medical issues, whether skin conditions, epilepsy, or others.
Given the many restrictions and conditions, it can be difficult to set up a fully legal and functional pipeline for the production and sale of CBD oil. Because different countries allow different activities with regards to cultivation, processing, extracting, etc., of hemp, entrepreneurs have often set up production pipelines that span multiple countries, where hemp is cultivated in one country, while extraction takes place in another, lab testing in a third, and sales take place in yet another country. This obviously makes it harder to determine exactly where a CBD product comes from, who is responsible for its final quality, and what standards were followed. For that reason, thorough analytical testing of final products by certified third-party labs is an essential tool to guarantee the safety and composition of CBD oils.
Online retailers: Most CBD oils are sold through online retailers. These establishments tend to have the widest product range, and many offer free doorstep delivery. Online retailers also frequently post product reviews, allowing buyers to compare different oils based on customer experiences to determine which is best for them. These reviews can also be used to evaluate the retailer based on customer service, delivery, and product quality.
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.
