Hmm... "teenager response at best!!!"? Yikes. You must know an awful-lot about the subject.
The vapour does zero damage to the lungs. Zero.
The ingredients apart from nicotine are food-grade, things billions of peeps eat every day... in much-larger quantities too. *
That leaves nicotine. Caused no issues for thousands of years and then suddenly circa the '50s things started to change. 3->5000 harmful-and-carcinogenic chemicals started to be added to plain tobacco. The rest is history of course.
* I'm speaking for myself and all those who make their own juice with judicious care of course. The minuscule handful who "accidentally" purchase vape juice containing vitamin E acetate (the worst apparently) and die (usually 2 or 3 teenage girls a year AFAICT) are unfortunate victims of nefarious activity, analogous IMHO to the young holiday-makers who get poisoned by ethanol in their drink cocktails in places such as Thailand.
If there's a flaw in my apparently-12-year-old logic, please point it out to me brother. As I implied, I suspect you've only seen one side of the story.
