not sure if anyone else has come across this, but i started work in an office about 10 months ago and they have just bought a new office that used to be a bar that had these amazing extraction units for smoking zones. well, i made a suggestion that since nearly all of us smoke in the office that we use the extraction units and continue to work and smoke instead of taking cigarette breaks. the management thought it was a great idea and we are now allowed to smoking at our desks!

the extraction units are amazing, you can see the smoke disappear up into the vents almost instantly. The non smokers, 2 out of 15 of us, said that they were really surprised at how good the system worked and can smell no smoke in their workspace whatsoever.
