NA isn't harm reduction but demonization of use, a slight but relevant difference. Idk, I've seen cases in which demonization was justified but I don't want to be the judging guy.
Kratom isn't magic unfortunately, it's just a plant based opioid, I didn't find much in it than aid to get rid of other substances, for opioid withdrawal dissociatives are superior but also more psychotomimetic. But the fact that Kratom is legal makes it interesting, and it is easier to kick than full agonists.
