mark my words.. vapor cartridges are probably way more dangerous to lungs than smoke
I know its just an anecdote but people YOU ONLY GET ONE PAIR OF LUNGS and they heal differently then other parts of your body (or they don't heal at all - COPD is TERMINAL).
I can not smoke cigarettes, never liked them, always got headaches from them. With vaping quality liquid I have no issues and I'm a heavy user. Not saying it's good for you but claiming it is worse or the same as literal smoke is just wrong
That sort of vape liquid is nicotine in a suspension of food/medical grade PG/VG and likely some small bit of flavoring in the same. It's essentially a tiny version of the fog machines that blast out vapor in nightclubs.
