Froze,
I'm sorry but your way off. Just becuase it doesn't work for you, doesn't mean it doesn't work for someone else. Did you even take the time to read the stories?
They weren't studies, they were stories... of real people, who found help from it.
Maybe when you used marijuana, you were using it recreationally, which usally means in higher dosages. There are medicinal dosages for marijuana, just like any drug.
I think you need to just realize that the world doesn't revolve around your experiences.
