Nope. I don’t think there’s any reason why heroin should even be manufactured these days. If you’re going to make painkillers from opium, they’ve got a million better options at this point.
That said, unfortunately we have people addicted to it, and I would rather see them getting high safely, on clean drugs, in a safe location than having them get hooked on fentanyl and end up dying of an overdose under a bridge. So it does make sense to continue manufacturing it for that. Otherwise, black markets will fill in the gap.
