I think it's a disgusting thing to smoke in the office, but (like in many other area) there are not really strict laws against smoking. Maybe later, but you don't want to wait till that time. In my office people are smoking as well, but fortunately they are far enough from me, so I don't feel at all. Maybe it's a good idea to quit.

It's true that had working hadn't killed anyone yet, but why to take risk?
