Yes, absolutely. I think that's critically important. The fact that people are using it is backed up by anecdotal data. Some people find it highly beneficial, but there is no single large-scale study that looks at the clinical efficacy to see whether it's really effective in a measurable way and, more importantly, whether safety is an issue with the use of those cannabinoids. They have other effects, cognitive effects, effects on concentration and on sleep, etc. that need to be looked at very carefully.
