"The concentration of these cannabinoids in the oil is infinitesimal"
So where are the cbd's in hemp? You still haven't responded to how this high CBD hemp is grown. All the research says that CBD is higher than thc in hemp. It doesn't mean that there is enough to extract.
Myth: Hemp oil is a source of THC.
Reality: Hemp oil is an increasingly popular product, used for an expanding variety of purposes. The washed Industrial Hemp seed contains no THC at all. The tiny amounts of THC contained in Industrial Hemp are in the glands of the plant itself. Sometimes, in the manufacturing process, some THC- and CBD-containing resin sticks to the seed, resulting in traces of THC in the oil that is produced. The concentration of these cannabinoids in the oil is infinitesimal. No one can get high from using Industrial Hemp oil.
