I am not gonna say that race doesn't have anything to do with it, because that would be wrong.

My own personal observations are these... 90% of the people(regardless of color) who get busted for weed, are busted because they did something stoopid. Standing on a street corner, toking up or selling, toking while driving, just blatent open use, or runnin your mouth. The other 10% are busted for weed as an "incedental" offense.

If you keep it private, don't draw attention to yourself, and stay away from vehicles, that will seriously reduce the chances of getting busted.
