Mexico Leads The Way?

The NYT debates Mexico's decriminalization of various drugs. Tony Paya:

[D]ecriminalizing drug possession is in and of itself a change of, paradoxically, gigantic and modest proportions... In the end the United States may be left alone to fight a 40-year-old failed “war on drugs” or join the rest and craft a more nuanced strategy to consider other possibilities in dealing with psychotropic substances. Perhaps this time change will come from South to North, instead of North to South.
