Ending the prohibition of marijuana: An empirical approach

Author Johann Hari makes a great case for the legalization of marijuana. Not only would it create a new stream of tax revenue, but it would substantially lower the crime rate and practically kill the black market overnight. One has to ask, especially after watching this video: for a drug with zero fatalities, why is marijuana illegal in the first place? Johann Hari's latest book is Lost Connections: Uncovering the Real Causes of Depression – and the Unexpected Solutions.
