Is vaping itself harmful?

148. The jury is still out

We know for a fact that when people inhaled diactyl for significant periods of time over a long term developed popcorn lung. E cigarettes use a different delivery and have not been in use for very long yet. And there is good reason to be skeptical of safety of inhaling a substance that we know has done damage over the long term in the past.
Kind of like the opposite of what people did with inhalation of burning tobacco and all of the chemicals that come with it. Unfortunately many of us were not sensible enough to give pause even when we knew it could do damage. I never denied the risk, but I overlooked it for a few years. I am very glad I stopped as I am seeing family members struggling with COPD.
Pretending there is no potential risk may help a person sleep well but it doesn't change the fact that we don't know for certain that there will not be damaging effects over time. We do know for a fact that the chemical in use has caused health problems.
