Arguments against the “war on drugs”

While I don't have any perfect answer, the global “war on drugs” smacks of the American prohibition of alcohol, something that ended up causing a lot of crime. If all drugs were legal, there would be no extraordinary profit in selling them and thus the crime that surrounds drugs would go away. Except, obviously, the crimes committed for making money to afford drugs (which is not an issue with rich people and would be less of an issue with poor people if drugs become legal and thus cheaper). What I'm not sure about is if free drugs would increase drug usage and, if that is true, there could be something done about that. The article “The Wire's War on the Drug War” has some more things to say about this topic, mainly that it leads to arresting the wrong people and that all of them are part of the lower class.
