So I was trying to respond to a thread but being I am brand new I can only post threads for whatever the reason? For the first 5... Anyway I've noticed that vaping leave a thick streaky residue on my windows in my house and in my vehicle on the glass so can see how thick it is and wipe it with you finger.. But I know it has to be better than yellow nasty tar left over from cigarettes.. It has to be better on your lungs than cigarette smoke...does anyone know anything about this thick residue left behind? And I've also noticed since I've been vaping the last 4 months sometimes I become winded and out of breath and I read somewhere that the hot vapor causes your lungs to swell for about ten minutes so I don't know if that's why I feel winded sometimes or if it's the thick heavy residue becoming stuck on my lungs? So does anyone know anything about this thick residue created from eliquid or if it has the ability to cause you to become winded? After seeing it on my windows I started to wonder what's it's doing to my lungs? And information or opinions will be appreciated! Thanks Sal.
