I wonder how that heroin stat will compare over a longer term. From what I understand, a common suggestion is that overprescription of opiods leads to abuse. Then removal of the prescription, tolerance gains, or financial considerations push the user to heroin. And once a user is hooked on that, I think introducing marijuana as an alternative is not going to have as much impact. But if reducing number of opiod prescriptions leads to fewer heroin users, I would expect there to be a measurable impact at some point over a longer term, at least in comparison to national trend.
