Yes it makes sense that we'd see arguments like this on a polarized issue. But these discussions end up in hypothetical territory quickly. Did we do a survey of nationwide opiate addicts that showed they'd self limit to less potent alternatives if they were legal? OR would they enjoy unfettered access to their drug of choice so they can use much more of it? Hard to avoid "just so" stories around all this.

People who abuse opioids are very price sensitive. Even in an open market, fentanyl's price advantage alone would probably be enough.
