So does this mean that Mexico is the new Amsterdam? :P

Seriously though, This is great news. Now we have a next-door example that legalization for personal consumption is'nt a recipie for disaster. As the years go by the statistical numbers coming out of Mexico will put the lie to some of the drug warrior rhetoric that we hear in america.
Also I hope Mexico sees a huge boom in tourism from college students and interested others going down a bit more often to get high legally. 4-20 might become more of a road-trip to Mexico hiliday for those within reasonable distance. I guess only time will tell, but this sounds like pure win.
