Well, from my experience of smoking in public places within Washington, be it parks, at the evidence impound lots, on the side of roads, middle of the freeway, most of the officers will not say a damn thing. I actually asked them a few times different officers and they all told me the same thing. It is not their problem, it is a DOH problem and they could not be hassled with it. However if smoking leads to a fight or a huge dispute they would have to act. Makes sense to me, I just suggest if you do smoke in public to do so respectfully and not give them any reason to bug you. Respect the 25 foot rule in front of buildings, and such.
