I disagree that the War on Drugs is a scam. It has produced very beneficial and positive results. In 1900, the addiction rate was something like ~2%. Today, the addiction rate is still around just ~2%. The natural progression of drug addiction without interdiction is a an exponential function that looks like this:
Chests of Opium imported into China 
China is an example of what happens when you allow drugs to be legalized in your country. America is an example of what happens when you don't. The Fact that we have held the addiction rate down to ~2% demonstrates that our efforts have been a great success. Had we not waged a war on drugs, our addiction rate would very likely be in the +30% range by now.
