You seem to be jumping from one extreme to another, where as I'm taking the stance of keeping things in their current state, as it's been, for the last 20+ years, which haven't resulted in the devastation of the US that you seem to be so worried about.

That doesn't mean open borders, just don't force all trucks through a full inspection. Check papers, ask a few questions, randomly inspect a few, and inspect those that are more suspicious looking. Seems to have been working alright to me.

I also don't know why you jump straight to complete deregulation of all drugs. Coca cola can't put bleach in the drink and yet I can buy bleach. Alcohol doesn't show up in kid products, and THC isn't suddenly put in kit kat bars.

Also from my understanding, it wasn't contained to pharmaceutical, it was that over prescription made people who would have not taken opioid of their free will become addicted.

And there's definitely studies and papers on the counter effect of prohibition policies in actually making matters worse:
