i dont think the FAA has any laws regarding vaping. im not sure if there are laws regarding not smoking around aircraft but that one's a common sense thing. you dont want to be smoking around fueled aircraft.... not smart. vaping does not carry the flamability issues that smoking does therefore there are no safety issues with it. you would litterally have to soak a PV in avgas and fire the atomizer to have any sort of safety issue and even then i who knows if that would be enough to spark a blaze..
also he told me no smoking. a provari and an itaste tank looks NOTHING like a cigarette. he must not even looked at what i was doing. last time i check cigarettes were not made of stainless steel and plastic.
Honestly when I fist started vaping its because someone showed me a cigalike from green smoke and being that I wanted to stop I gave it a try
but it was not till I seen this forum much later that I seen what a mod looked like
If I saw it on the outside for the first time wouldn't know what to think possibly for illegal stuff would come to mind
