Doctors becoming your drug dealer? Often, doctors start as your drug dealer.
Methadone is not a scam, it may be a very flawed method of chemical dependency treatment, but it's not a scam. Since you know what you're talking about, you are aware that the recovery rate for addicts is very low and the recovery rate for opiate addicts is even lower. That's not surprising, since in the case of a long term opiate addict, post acute withdrawal can last for months or sometimes years (in the case of individuals who have been using for 5-10 years or longer). While you may not like the methadone system itself, maintenance programs are logical and individuals who participate can get their lives back without having to go out and get a new job with the jimmy legs and a persistent runny nose.
The ideal system would be transitioning addicts to a maintenance program and, when they have sustained employment and good prospects, have a clinically supervised slow taper and then release them into the world like in White Fang. That's where methadone sucks. A slow methadone taper would take like 25 years. Methadone is not the right drug for the kind of maintenance program I'm talking about. We've got some awesome new prospects that doctors are working with, but the medical community has no financial motivation to transition from methadone to a newer, better drug - and that's where your critique is accurate. I know of a very prestigious rehab center who is in the process of implementing a new system for opiate addicts, and once the big ones lead the way, the rest will follow.
