Ohhh K but I'm hearing effectively identical rhetoric to what we've been hearing for decades about the War on Drugs, which makes me skeptical that the War on Fentanyl (I.e., aggressive federal government action being taken) is going to go any different.

Yes, this is a deadly drug. As is the case with any deadly drug, education and harm reduction are key, not checkpoints and tariffs that are antithetical to personal freedom, *and* ineffective at stopping fentanyl to boot (which due to its tiny dosing can be easily smuggled in passenger vehicles).
