I'd almost go as far as saying Kratom has linings of some of the effects that cannabis delivers. The bonus is you don't have to smoke it. That, and anyone who's been really high knows, there isn't any paranoia. Of course, some would say that strain, with both herbs, are important to consider as well. Let's not forget which one is legal in most of the United States, and the world.
I'd venture to say that Kratom could end up being a huge backer in the battle against anxiety. Use responsibly.
