Hemp produced in Europe is generally of good quality, according to Evan Kopelson, who has been a medical cannabis industry consultant for the past eight years. He notes in an article on Linkedin that until recently, when the USDA began allowing hemp to be certified organic, buying from Europe was the only way to be sure that CBD oil was pesticide-free. While laws have since allowed American companies to certify their hemp organic, some great CBD oil companies still source from Europe, so don't count them out of your search.
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.

A CNN program that featured Charlotte's Web cannabis in 2013 brought increased attention to the use of CBD in the treatment of seizure disorders. Since then, 16 states have passed laws to allow the use of CBD products with a doctor's recommendation (instead of a prescription) for treatment of certain medical conditions. This is in addition to the 30 states that have passed comprehensive medical cannabis laws, which allow for the use of cannabis products with no restrictions on THC content. Of these 30 states, eight have legalized the use and sale of cannabis products without requirement for a doctor's recommendation.
