We’ve tried everything already at great cost

Even if that's the case (I don't think it is), maybe we should try the things that cost a lot less? Maybe legalize it and tax the hell out of it? Cut out the illegal market by legalizing the sales and production channels? As a bonus, you will get much more accurate statistics about drug use, the effectiveness of countermeasures, and you get better quality control.

We also haven't tried the most harsh but cost-effective solution: flood the market with 100% lethal knockoffs, consequences be damned.

There are solutions to the drug problem, just like there are solutions to the alcohol problem. Going to war with a concept is just not one of those solutions.
