Hubby and I tried it a while back when we learned that kratom works as a stimulant more effective than coffee when used in lower doses. I did a little more research at that time. Evidently addiction is a bit of a problem where it's easily grown but here in the states and Canada it takes some work to grow. The trees are huge when they grow naturally and they require a lot of water, light, and heat so the herb is expensive, whether you use it for the stimulant or sedative effect. It also tastes extremely icky - not something you'd get used to. I suspect that it's kind of a niche drug and not worth passing laws on. The people who are willing to put up with the expense and taste long-term are those who have a reason to need it... or I could just be a nonaddictive personality.
