Looking for information on Kratom

My son swears by it for back pain and has been able to stop taking any opiods. I have tried it but could not get past the taste. It seemed to really help w pain but i started to heave at the smell of it by day three. I would have liked to use it because i am allergic to all NSAIDs and I’ve taken so much tylenol that i had to stop taking it except on really bad days. I wish you good luck with it. Keep us posted on how it works for you!
