@rascal, @Chris, This is a good article. Problem is the science gets very technical. Hemp is the cousin of Cannabis, and was used to make rope and canvas for the Navy back in the day. Stanley brothers have crossed bred it with a Charlottes Web a Cannabis plant, which was named after a girl it helped with epilepsy. So hemp sold OTC in stores legally only contain a small amount of CBD. Medical marijuana and strains cross bred with hemp can achieve different CBDS. Together they are much stronger in both THC and CBD that is not comparable to any hemp products for pain. In short the wide spectrum and content of CBD is going to come from plants with THC found in this need breed of plant called a hybrid. Not found in just pure hemp! So hemp in itself is a waste of money. Hope that helps.
