Just throwing some experience into the pile...
I've been an avid kratom user for....jeez going on ~5 years now give or take a year. I've been using daily with minimal breaks for a little over half of that time. My dose varies from ~7-9 grams, often twice a day on a habitual routine: Once in the morning after waking up, and another after lunch. Occasionally, I'll take a third dose at night but that's rare. I've shared kratom with many friends who have absolutely loved it, none have reported any issues, and I even have a few friends with kicked-harder-opiates-with-kratom stories to tell. Even with my usage at this level, I've stopped cold turkey many times before (WITHOUT any aides like weed or benzos) with minimal "withdrawal" symptoms, hard to even call them that. The absolute worst symptom is insomnia, and that only lasts a few days, if that. Nothing some benedryl and a couple glasses of wine can't fix, especially if you have some weed. This week, I'm trying to lower my tolerance simply to get better effects from my doses, so I've been lowering my habitual dose every day by literally a full gram each day. Hasn't made a difference to my days or nights whatsoever! No anxiety, no insomnia, no cold sweats, no potty issues, no depression, no craving, absolutely nothing. I've had things like phenibut, prolintane, and percocet cause more immediate dependence and subsequent withdrawal effects within a matter of days of use/abuse. Kratom and I are going on years, and we're still friends. Shit, even not having weed to smoke makes me drink like a fish... But kratom? Whatever.
I'd be lying if I said the thought of "I might be doing some harm by using this often, this much, and for this long" hasn't crossed my mind. However, I really have to say, nothing bad has happened, or seems to be happening. I never have any potty problems, I poop quite regularly and healthily. I have a healthy appetite too. I haven't ever experienced the mythical "jaundice" (which I believe was dis-proven anyway). I often check myself by skipping a dose, and aside from simply feeling like a part of my routine is missing, nothing bad happens at all. ANY distraction and it's out of my head. At this point, kratom and coffee are nearly on par with each other regarding their contribution to my daily life and their importance. There is not a single aspect of my life or my usage that is representative of a typical opioid-addicted person's lifestyle (and no, I'm not thinking that Requiem for a Dream is a typical addict's life...).
There is one thing I will say though. YOU CAN'T TREAT KRATOM LIKE A RECREATIONAL DRUG. Not only will you be disappointed, but you'll be sick from shoveling too much leaf into your face trying to force a "high", and you'll convince yourself of false things which leads to placebo withdrawals and side-effects. Kratom does not get you HIGH, it's not meant for that!! Kratom is an experience-
enhancer, not an experience-
maker. If you have disorienting effects, strong sedation, nodding, anything like that, you're taking way too much for your body. My dose is high due to years of tolerance building atop an already strong opioid tolerance, not because I'm trying to nod off. Maybe it's because I have this attitude towards kratom that it hasn't caused me any issues?
Keep kratom legal by not trying to get high on it. If people were selling coffee in headshops with names like "MegaEUPHORIA" or "Herbal Ecstasy" and idiots kept trying to get twacked out on it and kept ending up in ER's, that'd become illegal soon too. Kratom is doomed due to fuck heads and I'm pissed about it. You're going to get a good thing taken away from me and thousands of other responsible users because a few idiots who are too scared to try heroin or too anti-social to score some pills keep trying to get "smacked-out" on 20g's of ground up leaves....
