Way back when I first started
vaping (almost 2 years ago) my wife, daughter, dentist & dental technician, all non-smokers, were very impressed that they couldn't smell anything when I vaped in their presence.
Several weeks later my wife was riding with me in my truck (windows closed) when she blurted out something to the effect that "Why does your truck smell like coconut?" It was my
vape-o'-the-day, and she loved the aroma.
Only a few days later my daughter walked in to my office (at home) and, with an eye-brows-raised look on her face, asked "What's that fruity smell?" It was my blueberry
vape, and again, she liked it.
Those are the only two flavors (smells, actually) that either of them has ever noticed or commented on, and it seems to happen only when I vape in an enclosed space.
