I've never smoked. I'm borderline asthmatic, and it's just not an option. Even vaping puts a little stress on the lungs. The nicotine buzz is alluring though, so since buying digital for my wife's brother, and her taking up vaping, well, I'm hooked. I go through a cartomizer every 3 days or so...
Personally, I avoid vaping around the kids. Not because of health concerns, but because of my desire to not alert my kids to my new habit. I have no health concerns because I'm confident that the amount of nicotine that they may be exposed to is negligible and likely far less harmful than inhaling the outside air. I have read that we absorb 50-80% of the nicotine inhaled while vaping, so content is halved. When the vapor is exhaled, it dilutes dramatically as the vapor dissipates.
Would I vape in a closed room with them for an hour? No. I wouldn't even do that alone. Would I vape for 20 minutes before they entered a well ventilated room prior to their entry? Sure. Would I put out about 100 puffs daily in the volume of a 2,300 sq-ft house? Sure.
Lastly, I think I have a built-in alarm system. I am hooked on Vaporbomb's French Vanilla. When my daughter asks, "why does it smell like a candle in here?" after visiting the bedroom while my wife and I are vaping and watching TV, I know I've had enough.
