I know a few folks who have had a terrible time getting off of Kratom. Only one of which is totally free of it.
All of their cases were similar, going from a small brew a day the first week to doing 6-10g a day within weeks.
People I know who still take it regularly remind me of addicts to other substances - claiming they can quit at any time but since they aren't having a problem they don't choose to quit.
Yet they also constantly crave Kratom and freak out when they can't get it.
Of course there are a lot of legal addictives - like a whole range of mood altering drugs like Xanax, Prozac, etc. - which are far worse long term.
That still doesn't excuse the unrelenting hype that Kratom is safe and that it isn't addictive.
