Are you at all concerned that your own body produces pain-reducing substances that mediate complex biological processes -- and that supplementing them, via CBD and other substances -- could have serious, unforeseen consequences?

I think anyone who takes these substances under the belief system that they have little or no downside....is simply kidding themselves and conducting an experiment on themselves with an unknown outcome.

Best of luck to you.
