I have used Kratom, myself, regularly for the past 14 years and have not seen any of the anecdotal "consequences" of its' use bandied about. I have, in said time, however obtained multiple degrees and certifications, made a name for myself in my own industry now being a leading expert, provided for my family, and been a positive role model in my community. To claim Kratom has no purpose or is intrinsically dangerous is, quite frankly, close-minded and ignorant.
Some may hurt themselves with it as with any other substance. I remind you, people have killed themselves with water too. Stupidity and self-harm won't be prevented by banning this substance. Those who would will find another way.
