Saw this article about the difference between fighters on roids and fighters on weed, like Nick Diaz. Seems pretty relevant to what we've all been talking about, plus it's pretty funny.

As far as I'm concerned, smoking weed isn't a serious offense. I don't think they should even test for it. And I don't care what anyone says, I like Nick Diaz.
