I'm sorry that happened to you. Sincerely. That sounds incredibly frustrating, painful, and scary.
I think your maximalist conclusion of "drugs should be legalized" might have some second-order effects that might be net worse for society, though. Addiction, misuse, MRSA, overdoses, etc.
How do you contrast this stance with say, Vietnam, where drug prescriptions are not required? Is their society collapsing?
It’s almost like there are other factors at play, and our system is an inadequate band-aid on those issues that has its own side effects.
But it's part of this world. Who is to say who can participate in aspects of the world?
