Portugal's Experience with Drug Legalization

About ten years ago, Portugal decided to address a worsening drug use problem among its population not by enacting a war on drugs, but actually by legalizing the possession of drugs within its borders.  It's had mixed results, although from this article in the Boston Globe I'd say it has been positive overall.  Drug use is up, but drug related deaths are down.  Incarceration rates are down too.  I think the bottom line that countries need to address is what kind of society would they like to create.  Is it a society where drugs are considered a social harm and the use of illicit drugs an illness, or is it a society that considers drugs use to be a morally harmful problem that must be addressed through criminalization?
