I honestly don't know and I'm guessing, that we do not yet have the full story. It does seem like the lung damage and such they are now finding is in young adults and teens, not older fully grown folks. Young adults and teens tend to abuse, take things to excess a bit more then the run of the mill adult. Don't take that to mean adults don't play the fool too, they do. Most have chilled a bit though. So the issues from vaping could be the immature body or the use of the product. At least from what I have heard. So an adult trying to quit, at this point, I believe it is still an option with more upside then down. Only time will tell.
