On the other hand, Acetaminophen is used to supposedly make prescription painkillers less subject to abuse. I wonder how many people are killed by liver failure this way? That's pretty much intentionally killing people who could be put into addiction treatment.
Also a good point. My main point is when looking at drug deaths, the total should reflect (deaths caused-deaths prevented), rather than a raw count of total deaths. At least when looking at it from a macro, pure optimization perspective.
