When people have asked me if I'm "still" using it, I just explain that this is a hobby I've found enjoy and I'm perfectly content to continue with it the way some people knit, cook, or lob tree stumps for their hobbies. Put in that light, it separates it from the idea that
vaping is some kind of step-down program. Yes, I've decreased my nic level, but when I'm feeling ornery, I don't volunteer that info.
I guess we're lucky. I think the only problem DH runs into at work is that his cube mate has been working hard at losing weight and getting fit - and DH often smells like snacks - cappuccino, toffee, apple jolly ranchers - LOL.
