I think it is very easy to use some of the portable vapes in public, especially if you study how people observe. Really, to get someone's attention, you really have to go out of your way to catch it.
This is just MY observation: I may be wrong. As long as I don't give off vibes of suspicion, like furtively glancing around, huddling, or quick, jerky movements, I feel as if I'm invisible. Bringing something to my mouth is a natural act, not given to be overly scrutinized, unless it is your job to watch the crowd: even then, a slow movement towards the mouth, I think, looks benign.
Opinions?
