Funny. A similar thing happened to me years back when I was a teenager after getting pulled over. I had a ziplock bag full of calcium power. It's a supplement that I sprinkle on food for my pet turtles. Helps keep their shells and bones healthy. Anyway, I was a skinny white kid with dreadlocks and Grateful Dead bumper stickers so I guess the cops weren't buying my explanation. I think I spent almost an hour sitting on the curb while my car was searched (i had a lot of stuff in in my car) before i was let go...Not sure how they finally came to the conclusion that my explanation was legit. Did they have portable drug testing devices in 1997?
