The only potentially bad thing we so far don't know about vaping is anything related to long term use. Otherwise, it's documented, according to the science we do know, as a generally safe thing. It reduces harm from traditional cigarettes by at least 95%.
I'm not really interested in arguing about this. I address inaccuracies when I can because the FUD and disinformation surrounding vaping can cause vulnerable smokers to be afraid of vaping and continue on smoking cigarettes. That was me up until last March. I'm very, very glad I started vaping. My PCP was astonished when he listened to my lungs and said they sound clear. When I was smoking, they sounded like an accordion from my wheezing.
If just one hard-case smoker sees this, and feels ready to try vaping and get off the cancer sticks, it was worth it to me to spend some time here.
