Meh, I've heard the horror stories but I've been taking it almost daily since 2018 (except on weekends and vacations). I'm actually in the middle of a two week tolerance break right now, and the worst side effect I felt was a slight shoulder pain that went away by day three. (Turns out I was over exerting at work without realizing it because the kratom was numbing the pain.) And the depression's back too of course but being miserable is my baseline.
So no, I'm not worried about it. It doesn't even induce respiratory depression like a real opiate does, so the risk of overdose is next to nil. And I'm always careful to obtain my kratom from trusted sources, of course.
If you want to warn me about anything, you should be warning me about kratom's isolated form, 7-OH. While still not deadly, that little molecule is pure evil. It hits you like a freight train and wears off within 30 minutes, making you constantly thinking about next dose every waking moment. It's more intense than kratom, sure, but you don't get the same full spectrum effect (it's similar to the difference between live resin and THC distillate, if you want a familiar comparison). After a month of being chained down by this drug, I ditched the 7-OH pills and went right back to the powder. At least with kratom I enough relief from a single spoonful to have me feeling good enough to be a functioning adult in the workplace.
