The majority of the countries on this planet have similar drug policies to the US. They aren't all corrupt and in many countries the policies are quite effective. So to rant on like a crazy person about corruption and conspiracies just makes you sound unstable. There are many practical areas that the US can focus on like better border controls rather than opening up the can of worms that is legalising all drugs.
I only know of Singapore, where drugs carry a death penalty, and that's far less ethical than any kind of drug trafficking.
Also: I find it kind of amazing that there are still people naive enough to call me a paranoid conspiracy nut or "unstable" for suggesting that... gasp... there might be corruption in the world.
A paranoid conspiracy nut is someone who thinks that the world's leaders are shape shifting reptiles or that everything is run by a secret cabal linked to some kind of ancient secret society. I'm just suggesting that a large-scale illegal business with profits in the hundreds of billions and cash flow probably near $1 trillion might have an interest in putting a few people on the payroll.
Corruption was not the reason drugs became illegal and it's not the reason drugs are still illegal.
