It is credible to say that the Opioid crisis was actually a .made-in-Vietnam' crisis, in the sense that it gained a lot of traction from the returning American Vets from Vietnam, who were horribly injured (both mentally and physically) but ignored by the American system. They had no alternative but to seek solace from their emotional as well as physical pain in opioids.

Vietnam was the worst defeat of America in their entre history, It completely destroyed America. and for absolutely no good reason. Under the same system that America tried to quash, Vietnam is now an economic and industrial powerhouse, a major exporter to America.. A complete and senseless waste of American lives and resources. Moreso in that the bottomless pit for money became so all-encompassing to the American economy that funding for the entire space endeavor completely dried up, along with funding for physics research. America hasn't won a serious Nobel prize in Physics in decades.
