CBD is excellent for taking the edge and panic off acute and extended pain. I'm not a fan of cannabis in general, in fact I don't like it, but this stuff works. It also works on skin. I took it for two weeks last July, when I was on four different pain killers, including morphine for my back nerve damage injury and this was the added catalyst needed for pain relief and sleep.
I wouldn't hesitate to take it again. A little bit fuzzy like Tramadol, but not as much and more effective as pain killer and calming. In fact, I think Tramadol is the proletariat pain killer/placebo. When you take morphine after awhile, it stops you from sleeping, so the CBD is a good antidote to this. Of course, I was triple dosing on the 4mg drops.
Long term or social use? No, I wouldn't.
Haven't heard of Kratum, is it like that fantastic stuff that was doing the rounds back in the mid-2000's that was one molecule away from pure liquid MDMA?
