For the first few weeks at work, I kept asking my co-workers if they smelled anything because I did not want to introduce/impose anything into our work area which they might not want. For the most part they said no, unless they walked right by me, or into one of the smaller rooms I may have been vaping in...
Sometimes one co-worker and I are sitting in a 8x10 office and he says he has to deliberately try to pick out the smell as I exhale straight up.
During that time, I was vaping [PG] : RY4, USA, Coffee, Spearmint or some mix thereof.
Recently however, I started mixing/diluting about 15-20% [VG], and last time I asked, he said the smell carried further.
In any case, i've been told the smell does not linger more than a few moments unlike cigarette smoke. Our main work area is some 2000+ sqft with very little air-flow (no-windows that open)
