I've never been on methadone maintenance, but based on experiences by people I know and am aware of, I would avoid it. If at all possible, cold turkey or taper with codeine. It is one of the more mild opioids to become addicted to, not that makes it non-severe. If they're serious about quitting, I could see Buprenorphine being better to taper on, but I had a long..really bad experience with Buprenorphine and doctors that prescribe it. There's no way to know for sure if someone else is done getting high, but if they are, a quick taper process with Buprenorphine is as far as I would go with trying to get off codeine with opioids. There are other non-narcotic drugs to help aid you in the withdrawals.. I'm not too knowledgeable on those. I tried looking around at neversickanymore's posts with non-narcotic drugs for things of this nature. Seeing I'm not experienced with them, I'll wait for that post to come..cuz I'm sure it is going to come.
I was on oxycodone really bad for about 4months..really bad doesn't begin to describe the daily amounts of use.. I traded 2 weeks of hell for almost 5 years of it with Buprenorphine, but I wasn't done getting high. I was tired of being sick. I didn't ever go back to another opioid, but I justified snorting subutex by that.. The last two years I was mixing insane amounts of Alprazolam with it everyday, and I was miserable enough to accept an intervention and go into treatment, 1month inpatient, 3 months transitional, but just because I'm sober now, doesn't mean it's not difficult. I'm sure having a daughter almost 9 months into sobriety doesn't help me being tired all the time...but that totals to about 6 years of BS because I didn't want to bite the bullet and detox...but I also didn't have the self control to taper with oxycodone, and complications with my first doctor just showed me how powerless I was to addiction.
Just to give you a tid bit of my story, but from it, you might be able to see how I would be biased against maintenance drugs.. experience may vary..
