We source our hemp extract solely from USA suppliers as it is high resinous hemp. They use a special growing procedure that limits the amount of THC contained in the dry flower weight which allows it to be under the 0.3% THC designation for hemp. European hemp is the industrial variety which has been bred for seed and stalk. It has a low resin content which means it requires much more material to extract the same amount of cannabinoids. Since you are extracting a larger amount of material, there is an increased risk for pesticide and heavy metal contamination. You also lose a lot of the terpenes and flavor compounds essential to a full spectrum extract.
