I can't see why you would want to ban kratom.
Perhaps additional regulation could make sense but this is an incredibly helpful plant for the health of those who use it and there really isn't much danger associated with it.
It's nothing compared to marijuana and even that is being legalized.
This would be like banning chamomile tea because it makes you tired.
Please don't take away the plant that takes away pain for people without forcing them on oxy and has many other helpful benefits.
