I suppose the police are gonna have to add a nicotine field test strip to their bag of drug testing goodies to see if you are vaping with or without nicotine. In the meantime, we may be forced to deny having nicotine in our cartridges. I guess this goes along with the civil disobedience idea in another thread from yesterday... If PV's get classified as 'drug paraphernalia' then they are gonna have to have a way to verify there are drugs (nicotine) in them while you are using them, just like a water pipe, a (real) vaporizer, or a whipped cream dispenser.
