All Highland Pharms' CBD oil products utilize the same CBD extraction method from hemp plants that are grown in Colorado using organic growing methods.
However, there are many other CBD brands available on the U.S. market, and sources of CBD extract and isolate may come from plants grown in other parts of the world, such as Eastern Europe and China. Oftentimes, other companies buy their CBD from brokers who don’t know neither where nor how it was grown. For your safety and health, please exercise good judgement. If you don't know where CBD in a product is sourced from, we do not recommend using it.
