The US government lists Marijuana as a schedule 1 substance. This falsely implies that Marijuana (and therefore THC, CBD, and all cannabinoids) have no medical value.
This is in direct contrast to Patent #6630507 - Cannabinoids as antioxidants and neuroprotectants which patents the use of cannabinoids for medical purposes. One would think that the government would oppose this patent with their stance on Schedule 1 Marijauna. The thing is, they are actually the owners of patent 6630507.
