@Simp_Man yeah. Don’t do anything to your lungs. It’s nasty and has horrible affects afterwards. I have a chronic lung condition, it’s not super serious, but I do have to watch what I breathe in. In short, I would not recommend breathing anything but oxygen and whatever the doctors do, because the toxic stuff you breathe in with cigarettes, carbon dioxide, and other gases sicks to the walls and filters of your lungs, and can therefore make life even worse than it needs to be.
