New York Times:  ” nobody knows exactly how much the whole Mexico-U.S. marijuana trade is worth, with estimates ranging from $2 billion to $20 billion annually. But even if you believe the lowest numbers, legal marijuana would take billions of dollars a year away from organized crime. This would inflict more financial damage than soldiers or drug agents have managed in years and substantially weaken cartels. . . . It is also argued that Mexican gangsters have expanded to a portfolio of crimes that includes kidnapping, extortion, human smuggling and theft from oil pipelines. This is a terrifying truth. But this does not take away from the fact that the marijuana trade provides the crime groups with major resources. That they are committing crimes such as kidnapping, which have a horrific effect on innocent people, makes cutting off their financing all the more urgent. “
