Kratom seems too risky to try.
I've done some research, and that's my conclusion:
1) suppliers aren't monitored or held accountable.
2) there is no guarantee of consistency in the product you receive over time.
3) there have been no large studies done to even show safety for a bunch of 'regular' people, and most of us have immune systems which are NOT regular.
This is just my opinion, of course.
Here's the NYT on the subject:
