CBN naturally forms in hemp plants that are aged, oxidized, exposed to UV light, and decarboxylated. Decarboxylation is the process of heating the plant material to convert the cannabinoid acids into their active form. When the hemp plant is aged, it creates the CBN acid, CBNA (cannabigerolic acid). This acid is then converted to CBN when the plant is heated to a low temperature to activate the CBN without vaporizing the material. To create CBN oil, the CBN is extracted and isolated from the plant material and is then added to a carrier oil.
