I just watched the movie and 'kinda' liked it... He refers to vaping as smoking. :-\
"you mind me smoking?, it's not a real cigarette."
"what?"
"it's electronic, it uses the same amount of nicotine, but the smoke is water vapor, yeah, watch (Puff puff puff)."
then he puts the end against his arm then says "it's an LED light."
Oh, wow! I did that in real life. The first time I used my njoy NPRO in the bowling center after Virginia had outlawed indoor smoking, people were doing double-takes at seeing my vapor. I then put the end against my arm as if I were putting out a cigarette. That bought bug-eyed gasps. I then held it up, smiled and said, "It's not a real cigarette."
