I got that from my parents in the beginning. My dad quit cold turkey when I was young, so his first impression was the I'm "still smoking" Over the past 2+years that I've been vaping, however, he's gotten more information and has become supportive of it and has started recommending them to smokers.
As for when I'll quit vaping? Probably when they pry my PV out of my cold, dead hands. Alzheimer's runs rampant in my family and in the past 5 years my memory has already started to get fuzzy. There have been several studies suggesting that nicotine can aid in the reversal and/or reduction of symptoms so I'm going to keep at it until I have proof that it's doing more harm than good.
