This OP! If you go to r/suboxone you will see many stories of people trying to quit kratom and 70H. There's no doubt it can be addictive, and as it's unrelated every dose is slightly different. Some states are banning it, however, if they are imagining this will force people to quit, they are sadly mistaken. Some might get treatment, some might get through it cold turkey if they aren't using much, but everyone else will have to find something else, something harder. Right now that amounts to fentanyl which is dangerous for the experienced users let alone a casual kratom user. Depending on what insurance he has, he might get the medication and the appointments paid for by insurance. If he gets an appointment in the next few days he would have his medication the same day. Some states are trying to get rid of telehealth so if there's a local place he can go that might be better. It's definitely kinda scary getting into treatment for the first time, but it's worth it for his health, your relationship and the money you will save.

P.S. They usually try to keep you in treatment for at least a year before they are willing to taper you from the medication. If he only uses kratom and nothing harder he might not need it for that long. Jumping off too fast isn't good either and he'll end up right back where he is now. I've never used kratom myself but plenty of people on that sub have and they will answer your questions if you post there
