I quit smoking with vaping before, and I am trying to do so again. I am just wondering about a few things before . I saw an article saying that vaping at high temperatures releases formaldehyde and other chemicals. Also, am I getting more nicotine from vaping? I am using a gpriv with a cleito 120 and 3mg nic. I’m just a spaz when it comes to this kind of thing. I’m trying to quit smoking Because of heart disease in my family. So i’m just wondering if anyone on here has , had a heart attack, or any other problems and they vape? Also, has vaping showed any signs of copd or anything?
