I had been a smoker for years. I gave cigarettes up on Nov 28, 2012, the day my E-Cig starter kit arrived in the mail. I love to Vape... I especially enjoy being able to vape at work. Back when I started, there was a common belief that vaping was safe, at least that was what I had heard and read. Is it? I can't imagine that inhaling vaporized propylene glycol or vegetable glycerin is good for my lungs... Don't get me wrong, I am vaping with the understanding that the behavior can or could be VERY hazardous to my health. Ultimately, there simply is no research as of yet to determine the impact of vaping on health. Let's not continue to fool ourselves.
