I vaped a couple of times when a friend offered it, and the funny thing is I've actually been breathing better when I did vape.
Last year, when I was still a cart pusher, we had a huge fire out in the country. Because my town is surrounded by mountains, the fire smoke just literally laid in the town. Walmart was too cheap to give us masks, so I had a bit of lung damage. I found out that apparently ecigs and vapor pens have ingredients used in asthma inhalers.
I probably won't get into vaping, but so far it's actually helped me breathe better.
