All well and good, except for the fact that there's no evidence that legalizing drugs would make the costs or harm to society any worse than they are at present. In fact, most of the evidence points the other way.

Then there's the savings- in the billions of dollars- currently squandered on the useless "War [sic] On Drugs" that could be applied to something that would actually produce positive results for society- like treatment and rehab.
