How much concentrated CBD would be in these drinks

How much concentrated CBD would be in these drinks? Taking 5mls per day or more of 25% CBD could make those drinks very expensive. I don't see the benefit but I do see the marketing angle with the advances made by the cannabis industry with regards to getting it accepted for use in many states and tying a product to its apron strings. I think they are not going to see this happen at all, and finding a supplier who can supply the massive amounts required to manufacture and sell enough to even make a dent in the market. Personally this whole things smacks of promotion and mis-adventure.
