I heard on the radio the other day that some organization stated that vaping would save smokers lives and identified it as 'healthier'. With vaping, you do not inhale tar from smoke, it is vaporized nicotine, propylene glycol with flavoring that is commonly used in foods.
i'm undecided about vaping. i'm also just as clueless as anyone else is about its long term health effects as vapes have not been around long enough to observe long term health effects.
If you think about it, smoking places tar into your lungs. (Look at any photo of a smokers lungs) Vaping has no actual smoke from a burning item aside from nicotine and the flavorings, it's vapor. There are always nicotine patches if you want to quit.
