>I do use the gym 5 times a week.
Check my post above, this was literally the reason I stopped smoking and went to vape, because I was always getting out of breath and wasn't improving in that regard.
Soon after I stopped my efficiency went to another level. And fair enough, when I stopped going to gym regularly I got back to smoking as well (progressively though).

Even thought it tastes better and feels lighter, it is actually much worse for your lungs, the water vapor only makes it smoother, but still carries all that solid coal ash to your insides.
>My friend has some health issues after using vape for a while, he now uses inhaler.
I hardly think vape can cause asthma of any kind, the medium used is the same, glycerin.
Most likely he had the possibility already but only came to be aware after using vape, eg, it would me much worser for him if he actually smoked.
