Simply put, Industrial Hemp is virtually all the hemp grown in the world today. Non-Industrial hemp would be marijuana. Because of all the cross-breeding, there is little delineation between what is a hemp plant and what is a marijuana plant. Industrial hemp is the cannabis plant that is exceptionally low in THC.
What we call “Pharmaceutical Grade Hemp” is Industrial Hemp that has been specifically bred to have high levels of cannabinoids and is meticulously grown to ensure exacting and high standards.
