Do you mean generally or in this particular case?
Do you believe in the idea of switching from say Oxy to kratom to nothing? In theory it sounds good anyway.
I've been trying this method lately.
From what I understand it takes a few weeks to get dependent on kratom, so if you just take it for a couple you would presumably be over the oxy dependency and be able to quit the kratom with little discomfort.
I've never seen a drug that creates so much division, but I do think that the kratom evangelists are way out of touch. Just look at the wikipedia pages for it, for example.. they sound like advertisments and refuse to except kratom could have adverse effects which is counter to the little science we have.
