Opioid replacement therapy is the standard evidence-based model to treat people with acute opioid addiction, and that is unassailable according to every research study that's been done. If that is the evidence-based model, then why can't we meet the large-scale need that's out there? We can't because one, there aren't enough doctors who can prescribe [drugs like methadone], and two, there are these artificial limits [by insurers] on who doctors can prescribe to.
