Without getting into a lot of technical detail, it's a slightly different chemical compound, but it works very much the same way as methadone, and it's administered differently.
We introduced it because it's starting to be introduced in community programs and in other programs outside the correctional environment. It's been shown to be an effective alternative sometimes for people who can't tolerate methadone, or if for some reason methadone doesn't work for them.
We currently only have one person on Suboxone.
