I have been on e-cigs for over a year now. I have introduced several friends and aquaintances to them. One of my friends that has been using them for a while now along with his wife have found out they are expectign a child. They asked me if I knew any info on this as I read into e-cigs and their effects a lot before startign and try to keep updated on new infomation on them but I had to tell them I did not. That got me interested to find out and thought I would see what others on here might know. They also asked their doctors. As there is not lots of info or studies there were no straight 100% yes or no answers but this is what we have found. I as well as the doctors said that the nicotine would not be healthy / good for the baby as it could experience withdrawl as well as some other negative effects. Therefore if the nicotine was removed and only the PG liquid used is that an issue. There are several studies inolving animal tests that showed no ill effects on pregnant animals exposed to low to large amounts of Polypropylene Glycol over a 114 day period. We both found several instances of this. I am curious if anyone has used their e-cigs while smoking or what if any information other people found in similar positions. Obviously the answer is why take the chance or I would stop for m baby. I am interested in the scince or facts behind it or what others have learned. This should prove to be an interesting discussion I hope.
