think the evidence should be challenged about the real effects of marijuana in Congress. I think those who made it illegal should put up the scientific evidence. They should put up or shut up. Is this similar to banning Gay marriage on religious beliefs? How can this plant be good for medical purposes and then on the under hand you claim it is dangerous? I understand about cocaine but I don't get the reasons for marijuana? It needs to be discussed seeing that a lot of Americans have smoked a joint. Even a few Presidents. What was that crazy weed the Indians smoked now around the pow wow?
