There was a time, not that long ago, when cocaine was 100% normalized. It was a regular ingredient used in everything from basic OTC remedies to, most famously Coca Cola which was Cocaine + Kola nut. And Coca Cola itself was based on Vin Mariani, a wine mixed with cocaine that was drunk or endorsed by everybody from Popes to Thomas Edison and Ulysses S Grant. It was also regularly offered for free to laborers by employers because it was seen to observe productivity, and all other sorts of stuff.

So we were pretty much a nation of coke heads. It's probably much more difficult to see the harm in things when its so normalized. But of course people did and so the tide gradually shifted against it. We're already seeing the exact same process play out with social media and, more generally, digital addictions. But it's a relatively unprecedented technology in that it's essentially a digital drug that can't be especially well defined. But I expect these things are well on there way out. The age restrictions will likely come with broader prohibitions if they are positive outcomes from such, and we're already seeing exactly that in places like Australia.

Government and intelligence agencies desire to use it for mind control or whatever will probably quickly fade once they realize the same concept (which I think is quite frankly absurd - hence my sardonic term) could just as well be used against them, were it possible.
