More than one thing can be causing problems in a society, and enterprising humans of lesser scruples have a long history of preying on the weaknesses of others for profit.
The traffickers looking to pack more punch into each shipment that the government fails to intercept do.
Basically it's a response to regulatory reality, little different from soy wire insulation in automobiles. I'm sure they'd love to deliver pure opium and wire rodents don't like to eat but that's just not possible while remaining in the black.
Worse than enterprising humans are authoritarian humans who want to tell others how they should live, usually also exempting themselves from their rules.
They also prey on the weaknesses of humans and social appearances to do things for a "greater good".
There's a problem and we 'must do something' and if you're against doing the something I propose youre evil and I'll label you.
The real mindfuck is that sometimes, an unscrupulous entrepreneur only has to play your "societal harm fighting" game through politicians and they get their way and we lose.
