Big Pharma Stands to Lose $18.5 BILLION if Marijuana is Legalized Nationally: Is this Why the Current Administration is Attempting to Halt the Progress of Medical Cannabis?

A 2017 study on medical cannabis by NewFrontier Data looked at the economic impact on the pharmaceutical industry if medical cannabis were to become legal nationally: "In our latest study, From Prescription to Recommendation: How Cannabis Could Disrupt the Pharmaceutical Industry, our data analysts have found that if medical cannabis were legalized nationally, pharmaceutical expenditures on the top nine conditions commonly treated by medical cannabis could fall an estimated $18.5 billion between 2016 and 2019." Could the powerful pharmaceutical lobby be behind the current administration's efforts to try and crack down on legal cannabis in states where it has become legal? How else can the disinformation currently being published by the current attorney general be interpreted?
