Wild Hemp
Wild Hemp is based in the United States and has its products manufactured by the America Juice Co. If you don't know who they are, know that they're specialised in the creation of CBD e-liquids and concentrates. All of their blends are treated to ensure there's no THC left over.
We recommend you pour a few drops of CBD juice into your dripper, like you would do for a traditional e-liquid. Several CBD concentrations are available to you, depending on how you want to use it.
