Look at me officer!

Seattle long known for it's proud relationship with heroin apparently has a little soft spot for the ole' Crystal Meth as well. One resident has requested a vanity plate that read "C9H13N" and while this may mean nothing to the average lay-person the odd miscreant chemist would recognize this as the chemical compound for methamphetamine, Despite a law that does not allow references to alcohol or illegal substances on their plates, their is a loophole (besides the fact that 90% of people slept through their chemistry classes) since this compound also represents amphetamine which is legal in some medicines.

It is doubtful that this plate will be in use much longer since the owner has pretty much secured himself a roadside full-cavity search with every traffic violation. Those cops love a good riddle.
