On some of the flavors, my friends can smell it if they are closeby.
Or if we are in a very enclosed area, like inside a car.
So I try to be considerate, especially with the
tobacco flavors, which they seem to smell more than the others.
On the other hand, I was in a convention center all last weekend, and while I was indoors, I vaped my mint flavor almost exclusively, and nobody smelled it at all unless we were discussing it and I blew it directly into their face so they could try to smell it.
(I never do that without warning them, btw.)
My chocolate flavor was another one that they smelled if they were closeby, as was my strawberry.
Myself, I wouldn't try to vape at work undetected. I'd be upfront and tell.
I was amazed at all of the people who came up to me and asked questions when they saw the Prodigy hanging around my neck. It was very cool. And I didn't get a single negative comment all weekend.
