I don't believe that's true at all, the Federal MMJ program was shut down by the first shit Bush, and there was no abuse, the system was working perfectly. It was shut down by prohibitionist republicans.
As for the MMJ cause being hurt by anyone's actions, you guys are being too short-sighted about this. Anything that anyone does in the realm of medical use is good for our cause. And any Doctor that is writing recommendations is doing an heroic act. We should be forever grateful.
And no one can say that someone else doesn't have a legitimate use for marijuana. That is between patient and Doctor. Just because you can name your malady and someone else can't describe theirs is no reason to deny them what you have access to.
It can benefit all of us in many ways. Like Dennis Peron said, "All use is medical."
