It is not obvious how successful the war on drugs is, in part because it is not clear what success is.
Drugs cause deaths, and the war on drugs causes deaths.
One possible metric is how many people die from the war per death caused by drugs.
That is not a direct measure of success because it is relevant how a person is related to the drug. Also, changing one of the numbers changes the other too..
I would think it is hard to find absolute numbers for any of these, and even harder in a way that makes them comparable. I imagine it is hard because the numbers refer to different geographic regions, so they would be from different sources.
But there could be an estimate independent of the global numbers. That could be local numbers from some special situation, or based on a theoretical model.
Are there any estimates on the numbers, or the ratio of the numbers? Or at least which of them is larger?
