Methadone is an effective method of dealing with addiction for people with opiate addictions, but I think we've heard from other witnesses that methadone treatment is not always available and not everyone wants to use it.
Not everyone has an opiate addiction. Some people might be using other drugs. Cocaine injection drug use is something that we've seen is prevalent within the prison system, within federal prisons as well.
So it's not effective for all people. It's a very effective treatment, but prison needle and syringe programs are another component of a more comprehensive harm reduction and public health program.
