For pain management, both topical and oral CBD work well, typically proving the most effective relief when utilized together. Oral CBD also assists in the diminishing of symptoms from anxiety, depression and other mental disorders, as well as insomnia. Topicals work brilliantly at reducing inflammation, arthritis, headaches, cramping and migraines, and some evidence has shown that it can also heal eczema, psoriasis, dermatitis and itching.
An important issue in the discussion around cannabis-derived oils is: how much THC is a legal CBD product allowed to contain in order not to be considered a narcotic? Authorities sometimes choose to deal with these regulations in a pragmatic way, recognizing that laws once designed to control marijuana abuse may not be fully applicable to hemp. For example, in the Netherlands, a maximum level of 0.05% THC is allowed in CBD products, even though, formally, any detectable trace of THC is illegal according to Dutch narcotics laws. This approach is based on the fact that even hemp varieties of cannabis produce a small amount of THC, and therefore naturally derived CBD extracts will carry some THC in the final products.
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.

Prior to this, the only way to obtain a prescription was to seek the personal approval of the Minister of Health.
