I'm not calling for an all out sudden prohibition but to rehabilitate those already addicted while eradicating further supply of fetanyl.
Heroin and fetanyl are two very different beasts. While heroin seems to have a long use life for it's addicts, fetanyl literally kills because of it's extreme potency.
Carfentinil, the elephant tranquilizer is 100x stronger than fetanyl. There's no way we as a society can allow this to flow freely. It's no longer a drug but poison that absolutely kills its users.
