I have a theory that the most successful vapers were Lights or Ultra Lights smokers; that heavier smoke is harder to replace with vaping. As most of you know I was a non-filter smoker and vape high nic juice. I wonder whether the relatively low (to me) nic levels commonly found in juice are suitable because most people didn't get a great deal of nicotine from smoking. This poll is intended to test that theory.
Do you have a hypothesis along this line? I'm curious to hear it.
