Also, what do we know about the safety of vaping around our kids? We never smoked in the house with them, but long car rides would have us hanging out the windows

So I'm hoping vaping in the car isn't something to feel guilty about. I am convinced vaping is safer but is it 100%?
I cannot find the link now, but read a study done in the Netherlands that tracked the effect of "second hand vapor" on monkeys (I found it when I started my e-cig research in December '10 - will search some more and locate the link to post later today)
The results of the study indicated there were no signs that the second hand vape was any more harmful than water vapor - however, I remember after all my research there did seem to be some disagreement over whether PG vape was worse than VG vapor - but much of the nay-sayers were posting lines like, "That's (PG) the same stuff that's in anti-freeze" and gave a fire and brimstone lecture about the evils of vaping without any links, footnotes or data from research/studies to support their take on things - that always makes me suspicious -(and why I will find that link to the study, by gummy, before I'm done! LOL)
For myself, I now vape (either pure VG liquid or a juice with only 20-30% PG) in the car and in my home - my mom, who lived with a smoker for nearly 40 years is not bothered or affected by it at all - in 15 years, who knows? But I am 100% convinced that the vaping is not as damaging to the lungs as the smoke, because I switched to vaping when my chest pain still had not gone away a full year and a few months after having pneumonia. After vaping, it would go away, but let me have a real cig and within 5-10 minutes, the pain would be right back.
I would also caution you not to take full responsibility if your child does decide to vape in the future - a neighbor told me her teen-aged daughter and friends were in the mall the other day and a salesperson from a kiosk for e-cig stuff had them try a zero nicotine e-cig, waxing eloquent about how many flavors there are and how they didn't have to worry about addiction because there was no nicotine. The neighbor asked me, "If there is no nicotine, then what is the point?" To which I agreed.
I'm also convinced the "smoking" war has become so entrenched in our society, that you can read all you want, but there will almost always be a lot of information out there that is skewed one way or the other - each side has it's prejudices.
I also keep in mind that in the 70's, an improperly done study convinced millions of doctors and elderly people to quit using salt in hopes to avoid heart disease/attacks and then in the 80's they backed off when they found out too many elderly people were dying from sodium deficiency - -
Vioxxin was on the market for years before they discovered it was causing strokes - -
There are times you just have to research as far as you can, look at the pros and cons and then make a decision and hope it's the right one.
For me, I'm fine with vaping around my loved ones, I'm convinced it is a much healthier alternative than smoking and for now, that's enough for me. At the same time, I sprout my wheat before making bread out of it, have a milk share so I can get raw milk for my family and am starting my garden so I know what's been sprayed on the vegetables I'm eating - - - many in my circle think I'm nuts - but I research and read more than most of them and I tend to follow my own head/heart than rely on some "expert" to tell me what I should or should not be doing - therefore....
Disclaimer: I also practice medicine on myself - - so remember that fact when you take into account my two-cents worth of opinion....LOL
Children don't always listen to what you say, but they are always aware of what you are doing - I'm convinced children and teenagers rebel at the level they do out of pure frustration at being continually told how to "be" when they constantly see the mess we adults are giving them for their inheritance of the world - - therefore, I treat my children as adults who are shorter than me - - yes, this is what I'm doing....this is why....for you I would like....but in time, that's a decision you will need to make for yourself....and here's all the opinions from both sides of the matter......
My oldest son died from bacterial meningitis a few days after graduation - so I have a somewhat different perspective - - he had a clean home, nutritious food and a mother who took him both to regular doctors and holistic providers and he still died - - sometimes you can do everything you can think of and the worst happens - - - There are plenty of websites out there that are advertisements for all the vaccines available for meningitis now - here's the test you take to see if your child is at risk:
"Does your teenager:
A. Sometimes not get enough sleep?
B. Drink from a bottle or glass another teenager has used?
C. Attend functions where there are large groups of people (i.e. movies, dances, concerts)?
D. Often exposed to second hand smoke?
"If you answered yes to one or more of these, your child is at risk of getting meningitis - vaccinate them today"
Pardon me, but that's like me saying, "Are you alive and breathing? Then you're at risk of dying. Take this pill today!"
There, I think my "disclaiming" is done.
