Heh, I've got a big marijuana leaf 10k gold pendant that's gotten some notice before by cops. But I only wear it when I know I have nothing on me, just to hassle them by making them waste their time. When I might or might not be carrying something, I had a custom 14k gold earring made from what was originally an ankh pendant. Not that ankhs have anything to do with pot, but they look cool.

Here's couple pics, one of the bigass pot leaf pendant, other of my little ankh. Pretty amazing that they survived the house burning down last year!
