> I'm not exageratting... I've never met a caucasian person who's been arrested for marijuana posession. Never.

You can meet one now, on HN! I was arrested in 2011 for having ~3 grams of marijuana in rural Maryland. I am Caucasian. Got cavity searched and sat in jail for about 18 hours. Without going into too much detail, the charges were still dropped - apparently the police officer who arrested me had a bad track record of illegally detaining people. (It is questionable if my race had anything to do with their willingness to drop charges of course, but that is a totally different discussion.)

In any case, I wonder if this would have happened to me if MD had passed their decriminalization laws earlier? I've since moved to Washington State.
