i stopped using nicotine in my liquid in 2015, when it became more hassle to add it than not; laziness won!
i stopped vaping in Sept 2017 when vaping became more hassle, carrying gear and batteries, than not; laziness won again!
Dennis would be proud of me. i expect i'll die of a heart attack, not because it's diseased, but because it's just too lazy to beat anymore!
HRH still vapes and does so using the same strength juice as the day she stopped smoking and that's fine. Most of my gear is custom made, so in a collector's market there are no rules. My Reos that are not modified are an original copper vein grand and a working silver vein vv grand, but i'm selling none of my stuff because they are to me priceless and evidence of the process i followed to stop smoking.
