Nobody really knows the long-term effects of
vaping.
Welcome to reality.
What if we find out, 5-10 years from now, that extended exposure to the "harmless" ingredients in the vapor, as well as just the prolonged and constant exposure to the vapor dries up your tracheal lining and causes sores/holes to open up in your tracheal lining.
...Just one random thought. Also, look up the effects of menthol on the
throat, and the lining of the inside of your throat.
Regardless, I'll take
vape over smoke ANY DAY!
