I was an avid smokers for a long long time. I then quit and a couple of years later starting vaping. Vaped a couple of years and then started having my chest hurt after a long day of vaping. I finally wised up and quit vaping too. Now I just breathe air which is what my lungs were designed for. Took me a lot of years of my life to figure that out. People think vaping is harmless. Wait for years to accumulate for the actual affects of prolonged vaping start to come in and and people are going to see how stupid they were vaping. The pure volume alone of a single vape into the lungs is multiple times more than the equivalent drag of a cigarette. And people who don't think the lungs having to continuously clear that volume of vape over years isn't going to have any kind of effect on the body are only fooling themselves. I used to be pro vape, now I'm anti cigarettes and anti vape. This is not a good thing we are introducing to our youth. We created a ticking bomb with cigarettes and now we've created another one with vaping.
