This is sloppy journalism. Dronabinol is not a cannabis derivative. How can you study the effectiveness of cannabis if the product you're testing is a designer drug? It will provide some pain relief in the target group, however. A legitimate test for the effectiveness of cannabis therapy, I think not.
I agree with your assesment of the socialist health care system.
