I just wanted to say.....I don't smoke anymore (1 month today actually!!)!! And yes I agree that it's a disgusting habit.
However, I think that saying that smokers slack off more at work because of smoke breaks, etc. is a huge generalization and it's quite offensive. I smoked 10 years and my work performance was always 100%. I went for a smoke when I had a break and it didn't effect my work performance at all.
This seems to have turned into a "let's hate on smokers" thread. There are plenty of things that people do that are equally bad for them so lets ease up a bit here folks!!
Not wanting to offend anyone here...just had to say something.
