Yes, it's true, we do see patients getting into trouble, and you can't strictly just stop a medication. In a lot of cases you need a systematic way of helping them to reduce.
I think a big part of what pharmacists also do, because they see their patients so often, is get a sense of when patients are getting into trouble. There are visible cues with, for example, patients refilling their medications early. You get a sense that people may be getting into trouble. I think an important role pharmacists play is to let members of the team become aware of those situations so they can intervene and provide addiction management services.
