It sounds to me like they are talking about those "vaporizor" devices sold at certain shops which heat up and vaporize dried materials. Those are electronic, and look a little like ecigs, but they do put off smoke instead of true vapor. I had a guy try to sell me a 200.00 version recently because "then you can vaporize dried tobacco, it's healthier than cigarettes!" Those are the "in" thing right now for people who want to do…stuff…without bothering the neighbors.
If it were me, and if I'd lived there a while without feeling like the apartment complex was managed by irrational Nazis…I'd just ask. Chances are pretty good that they aren't talking about your kind of vaping. Even if you "draw attention" to yourself by asking, you're going to either draw attention to yourself anyway by vaping on your lanai…or you're going to vape inside only and not get the full enjoyment out of your property, possibly unnecessarily. Wouldn't you rather just know for sure?
