Texas Gov. Rick Perry (R) expressed his desire to legalize marijuana while speaking at the World Economic Forum in Switzerland Thursday: "after 40 years of the war on drugs, I can’t change what happened in the past. What I can do as the governor of the second largest state in the nation is to implement policies that start us toward a decriminalization and keeps people from going to prison and destroying their lives, and that’s what we’ve done over the last decade."
