I have done my detox in a hospital, with specialized doctors. Then continued my treatment as an in and out patient. And again, this is not something you see pretty often, statistically speaking. Not so many people are willing to quit methadone, not as many as in other opiates.
I have seen so many people quitting the recovery after a little more than a month. Of course this applies to heroin too, however atm I'm referring to methadone. I'm not an isolated case or else I wouldn't be sharing that.
Everyone is different we all have opinions, and obviously you've got yours. I've been on both sides of the isle. Besides, methadone disposal is legal and fairly easy for most people who want to quit other opiates. Methadone patients tend to use this medication for years and years and have a totally normal life. And that makes the entire process even more difficult, socially speaking as well.
That makes me remember when heroin was applauded because it was the cure for morphine addiction. Besides there are so many clinics available for methadone. Imagine you learn to live your life without many problems, out of the street, safe. Work and totally capable to raise a family. Disposal guaranteed. The effects 24/7 during 365 days a year. It's in your bloodstream for ever, not only just eventually few times a day or per week. Why would you want you quit? So there's clearly the motivation aspect too.
I agree that this is a very complex subject, no doubt about that. But I learned the hard way not to underestimate methadone.
