Cannabidiol (CBD) is a component of the cannabis plant that has therapeutic benefits. Unlike THC, CBD generally has no intoxicating effect. Since it is a component of the cannabis plant, it is controlled by The Cannabis Act. In order to make CBD products, you will need a cannabis processing license issued by Health Canada.
While CBD can be extracted from hemp, hemp producers may not extract the CBD themselves, unless they also have a cannabis processing or research license. It is prohibited to import cannabis products into Canada for the recreational market, including CBD products. Cannabis can only be imported for medical or research purposes. Importation for use as an Active Pharmaceutical Ingredient (API) is a medical purpose.
