I suggested the same before and used the exact same example, Portugal. Then all brownies jumped on me and denied the success Portugal experienced by legalizing and decriminalization any and all drug use. Now idiots like Achilles like this idea. Guess for right wingers they eat anything depending which hand feeds them.
About time they stopped subsidizing America's drug on wars. Tough economic times ahead for our neighbors down there, don't see why the government shouldn't look to trim the federal budget towards the drug war.
I'd take it a step further and just legalize everything like Portugal did, not like the citizenry has a big addiction problem down there anyway.
