Yes, there are accidental overdoses where someone takes too much of a prescribed drug without realizing it or accidentally combines it with someone that amplifies the effect and results in death. That’s a different matter.
Many opiate addicts who die of overdose are essentially (oftentimes even openly) accepting they’ll die due to the drug someday. We treat PTSD-affected soldiers as humans who need assistance in pulling through their difficulties before making an irreversible mistake. But we treat drug addiction as a problem regarding the addiction itself, and not that people with troubled circumstances fall into drug addiction out of despair or other difficulties in life.
But I think attitudes regarding this won’t change because the US will instantly shoot ahead of the world in suicide death statistics—in a shame-based society that’s all about saving face like the US, that’s simply not going to happen.
