No, vaporing is way less unhealthy than regular smoking. - and also doesn't hurt the people around you.
You just shouldn't vape on high temperatures because of the formaldehyde that could build up which is toxic. Main problem is that there is not enough data about vaping since it only became a trend in the mid 2000's.
That's interesting! I talked with one of my earlier caregivers, she had a husband that was an avid smoker. She tried vaporing with him but he didn't take well to it. Oh well!
