Thinking about the Bertrand Russell quote: "Drunkenness is temporary suicide", and wondering about the correlation between ~70k drug related deaths per year and this topics ~40k suicides per year. Would suicides increase if the easy access to palliatives would be stopped? Or would they decrease because it may be the drugs themselves that drags people down? I assume that the latter happens, but it seems to me that there's a root cause there before the heavy drugs exacerbates it.
