We would need the exact law quoted here or a link so that we can read it fully..
Well, the original quote in this post is how the State of Rhode Island defines "smoking" under its smoking bans.
Another idea would be asking the state exactly what this includes.
Well, this being Rhode Island they'll be very vague in any response. Our state prefers to make things up as we go along. Specific rules, laws, and even explanations are only passed when unavoidable.
Heck, we were the last state in New England to go "smoke free" and even then the rules were so vague as to what venues were and weren't covered that it took a year full of lawsuits and countersuits before the State finally just banned it practically everywhere.
The only way to really know is to get caught using it.
Best case scenario is cops show up and say you're fine to use it.
Worst case scenario is cops show up and think you're "being a smart guy" for using such a thing and pummel you with their nightstick.
Rhode Island is a strange land...
