Is vaping bad for your lungs?
I’m not entirely sure, but I can get some information on the topic for you.  I’ve found a few studies on the subject and I can bring them up for you.  Does that sound good?
Well it’s clear that nicotine can be extremely harmful to the lungs if consumed in high quantities.  That said, it’s unclear to me whether the lungs can be harmed by nicotine at concentrations associated with vaping, and whether vaping can be safer than smoking.
