There will be proper controlled trials soon, there is no substitute. However, it's worth noting that most complementary therapies actually do nothing - homeopathy is the classic example. Of course, we know many people find them helpful for a variety of reasons, but they actually do not have any physiological or pharmacological effect. CBD on the other hand is definitely a psychoactive substance, which may have side-effects. I think this actually makes it more likely a priori that it is a useful treatment. Put it this way, say we didn't know about CBD at all, if a drug company discovered CBD in some kind of drug screen, they would definitely test it and advance it into clinical trials.
