I bet that CBD will be covered very quickly, because it really does work very well for so many things, so it shouldn't take long to have enough studies clearly in support of it.
(Although anecdotally the best results are obtained from taking mostly CBD with a tiny bit of THC; it appears that the latter does something that makes the former's effect more potent. So you see stuff like e.g. 20:1 CBD:THC pills around - can't get high on that, but very effective at pain management. However pure CBD pills are still more common.)
