I never did this, but ought have. One college professor at my "smoke free" campus would smoke, as he was teaching. He'd use a piece of paper for his ashtray, or perhaps an empty pop can. I never did put flash paper, or a dry pop can with a bunch of gunpowder, in the trash can.

I have an allergy to cigarette smoke, and one idiot thought that it was funny to light up and blow the crap in my face. I asked the manager to remind them that the building was supposed to be smoke free, but he didn't care. One night I emptied an entire can of Lysol into the ductwork. The jerk light up the next morning and took a deep drag, and almost passed out. He ran to get the manager and was screaming like a little girl that I had tried to kill him. I smiled and told the manager that I had sprayed the ductwork to rid it of the nicotine odor, and that I would have to keep doing it, till it was gone, and reminded him of the million dollars worth of electronics across the hall wasn't supposed to be exposed to smoke. ;-)
