NEED A CREDIBLE ARTICLE ABOUT LEGALIZATION

I'm writing a paper for English 104 about the legalization of marijuana. I'm all for it but I need a credible article, like from a doctor or a professor that talks about the pros of legalization. Things like medicinal purposes, decrease of crime where it's decriminilized, things like that. Please give me all the links so I can write a good paper. Everyone in my class seems really intersted in my subject topic so I want to make sure I write a really good paper so they'll see my side of the argument and be more open minded.

Thanks,

CK:pimp:
