Enjoy your day and be safe. Why are people acting surprised that vaping is causing lung disease? I watch the amount of smoke that comes out of a person’s mouth and nose after they take a puff from an E-cigarette. Just a little fowl air messes with your lungs so I believe from the moment someone smokes an E-cigarette, their lung feels the effect and reacts, but the smoker ignores the uncomfortable feeling. Why smoke in the first place? Your lung hates it, but you keep doing it to keep the manufacturer wealthy.
