Why is alcohol better than marijuana?

I've read some very ignoriant submissions that attack marijuana, from people that seem to believe that just because they thought of it and it sounds good must make it true. I believe you must have SOME sort of experience or knolwedge in some way to form an opinion. So I ask to everyone with a six pack in their fridge or a bottle in their cabinet, what makes a non-addictive, non-leathel drug worse than the m murderer known as alcohol that has single handedly stumped evolution and stupified the world?
