I don't think that it would do much good. Compare the difference between your proposal and abolishing Prohibition. When the US abolished Prohibition, beer truck drivers became beer truck drivers. Bartenders became bartenders. Brewmasters became brewmasters. BUT the criminal element just moved into other criminal enterprises like: corruption, drugs, gambling, protection; etc. The drug industry is huge. These people have become accustomed to a better lifestyle. They are not going back to growing corn on a dusty hillside or working as unskilled laborers. I would expect the consequence of abolishing cocaine prohibition to result in a huge increase in other criminal activity. Protection would probably be the biggest, and that could easily spread across borders.
