Fair enough, as far as opposite experience goes.
Up here, doctors are notoriously difficult to get any kind of opiate from now unless you REALLY need it. Which in turn I would say has led to people relying on the grey market more and more, which has in turn led to our fentanyl crisis.
So I don't entirely disagree with you here, but I still don't want government being able to tax these things. We need a better solution.
