Yo I've vaped before but is the science behind it really any different from smoking? I know it's (alcohol?) vapor rather than smoke but does it still fuck with your lungs? Last time I vaped it was a sticky substance so you cough a shitton anyway.  After quitting smoking it was tough as shit to pick up cardio. Ive seen a few other "I smoke regularly but still do cardio" posts on the internet, and wonder how. I mean I can occasionally smoke socially at a party but its always a little bit harder the next time I get to the point where you're breathing heavy during your exercise routine.
