The most important piece of research we could do is a well-designed research trial to get the effect of very specific compounds for very specific conditions, and that's what's lacking. I think an anecdotal report, a patient or user reporting positive effects, is very valuable to start that process. But at some point I would strongly support the idea that we need a well-designed randomized control trial to test whether cannabis or cannabinoids may be helpful for specific conditions with specific dosage, which is not the case at this point.
