2. You should post links that contain evidence for your claims, instead of links that don't.
I'm sorry to be glib here, but surely you can see the problem with telling ME to go find evidence for YOUR claims, when you can't even be bothered to find evidence for your own claims. Given that you aren't presenting any evidence for your claims, I think it's highly likely that no such evidence exists, and I'm not going to waste my time searching for evidence that likely doesn't exist.
Beating a dead horse a bit: the link you've posted still does not say that cannabinoids have ever been part of the human diet.
I strongly suspect that I've actually read more on this subject than you have, as you've failed to mention Michael Pollan's Botany of Desire, which actually explores the coevolutionary history of humans and marijuana. Although Pollan still doesn't make the claims you're making about CBD oil, he does at least survey some evidence for coevolution between humans and marijuana.
So you have read enough to see but you need some sort of proof aside from the fact humans have been using it as feed for as long as history has been recorded ?
Given the fact humans didnt even know they had the endocannabanoid system until the 90's I am not surprised there isnt technical evidence showing the correlation.
Common sense should prevail here, but you are correct... even though the cannabanoid receptors are one of the most populous receptors in the brain and folks using CBD oil have been reporting all sorts of interesting reactions to it ( I personally can tell you it relieves pain from nerve damage ). Nothing in the links I posted directly correlates anything.
Odd how the money in the cotton industry lobbied and killed the hemp industry isnt it?
Trivia ... US Constitution is written on Hemp Paper
It is true that paper, and a very large proportion of fabric, were made from hemp until William Randolph Hearst orchestrated a fear campaign about "devil weed" to create a larger market for his timber holdings.
There was quite a lot of resistance to paper made of wood. It was acidic, so turned brown and crumbled in a short time, and was generally of lower quality than hemp paper. The quality problems have been addressed, since, but wood still takes quite a lot more processing to make into useful fiber.
