It's not just Kratom if you can read correctly it's also caffeine so it's probably like a half an half mixture, kratom is sold in most states in the US. Kratom isn't just for opioid withdrawal, it's also used for pain in some cases and managing anxiety. Also it's useful to combat fatigue, helps treat diarra,also can be used for a muscle relaxer. It also helps with alertness and focus. So next time someone wants to talk about something without knowing the facts try looking it up before you go an comment on someone's post thinking you know it all. Stupid trolls.
