Why do people hate marajuana?

i smoke it all the time and im doing fine it does nothing but make me care free of the stupid little things in life and makes me think more deeply about how to solve a problem the best way possible if im driving i get "paranoid"witch makes me more cautious and aware of other vehicles it relives my stress so im guessing that reduces my chances of a heart attack and an aneurysm it also helps me sleep and when i get the flu and i smoke i dont feel nousious.I think it should be my chioce to smoke this plant that goes strait from the ground and into my bowl,its a plant that god put on this green earth for me it wasnt made in sombodys bment or bathroom no added chemicals just pure plant thier is no links to cancer either unlike cigerets why do you people let the government controll your lifes even more be an american and be free
