the vast majority of the politicians responsible for the 'war of drugs' are dead. The ones that continue to perpetuate it are not being held accountable for anything, let alone the WoD. So by continuing to point fingers (at politicians), what is being accomplished?

The only movement that I have seen is at the State level, where the people are literally telling the "authorities" to GTFO and legalizing (or decriminalizing) at the state level. If anything the politicians are reaping the rewards by playing both sides of the issue. Blaming them doesn't work.
