Big difference between vending machine at cost fenatyl, and Rx controlled harm reduction expensive-ish fenatyl... You don't get war on drugs stupidity with tobacco tariffs, and if alcoholics only have access to the opiate equivalent of pure vodka, those alcoholics are going to do a lot worse when they have access to a spread of options.

Today you still get it cheap and uncontrolled beyond the queasy uninitiated, you fund organized crime and you get more humans into horrible cycles of criminality when they didn't need to be.
