Doing scientific studies with a Federal class one substance and enough subjects to get meaningful results is a challenge. That's been very convenient for those who discredit it's medical use. Also, since the benefits have never been proved, obviously my credibility (and that of others) is zero. (I knew a woman who regularly got so sick from crises resembling sickle cell that she would have to go to the emergency room to be "fed" IV since nothing would stay down; not even the rice she grew up eating. With that illegal substance, she could eat like a horse. Huge, huge life improvement.)

Some of us knew of the medical benefits of marijuana long before any of our states legalized it.
