I suffer from nuerofibromatosis I have tumors on the optic nerves of my eyes. For 10 years I used marijuana as a way to treat my migraines. When I was a kid I use to end up in the hospital because they were so bad and they had to put me on morphine -which would just make me sick. Thank God for this plant. Because if it wasn't around my life would have been full of pain and a lot worse.
