@icare4america I'm skeptical that this can be accurate. 1. Vaping hasn't been around that long and most vapers are firmer smokers. These 2 things would make causality very difficult to pin down. On top of this, the activity itself, is a way of coping with stress, so the stress could be a contributing cause. Then there is the vax. It would take a very long time and several studies to nail such a thing down.
