As of this writing, 13 states have passed legislation legalizing medical marijuana. President Obama’s pledge to stop raiding medical marijuana facilities was met with praise from opponents of the drug war, but what does it mean for the future of drug policy?

In Monday’s Cato Daily Podcast, Rob Kampia, executive director of the Marijuana Policy Project, explains his organization’s goals and strategies for ending marijuana prohibition in the United States.

Our society is not quite ready yet to completely end marijuana prohibition. So what we want to do is keep as many people from being arrested and put in jail as possible in the short run. One way of doing that is to legalize medical marijuana state by state.

Kampia spoke at a policy forum on medical marijuana at the Cato Institute in March.
