You'll be pleased to know that multiple countries elsewhere do worry about this, and will continue to publish evidence-based recommendations about appropriate drug usage. Every other member of the G8, NATO, AUKUS, and so on, all publish science for free, so as the US declines into a corruption-fuelled failed state, there will be access to that material still. I saw Mexican emergency services helping in Los Angeles the other week during the fires - more mature and capable countries are always here to help, even in very direct ways like this, where the US public sector is too fragile and broken to support their own citizens. There's been a rich history of this happening across Europe and Africa for decades, so others know what to do.
You might think I'm being sarcastic, or patronising or somehow trying to belittle the US. I'm not. That's where the country is now. It's failing in a way we've seen others fail many, many times before. The future is predictable, and it doesn't seem like anybody wants to change it.
