I think that it depends on where and when you smoke, and your rules at your workplace. For instance, it is probably okay to smoke outside on your break time, but probably not inside or too much during your working hours. However, I do not know the exact rules of your workplace or how you practice your smoking habit exactly. It would also depend on if others complain or how flexible your boss is. It might be a good idea to find out from someone what the rules are if you are unsure. Hope this helps.
