Smoking cessation

Just a real quick question on this as far as a patient goes. My book seems a bit vague, and this seems like a question that could be asked.

If you are trying to educate a patient to stop smoking, how should you handle them "cutting back". I know there are meds and what not that can be used, and some I have seen some say you can keep smoking for a while after you start them. I personally think if all you can get from them is an effort to "cut back", that is better than saying "you need to quit... period" because than they will just throw up their hands and say screw it.

But in NCLEX world, what is the right answer? With overeating and exercise they want you to set realistic goals, but the way our society views smoking through the lens of PC I thought perhaps smoking may be viewed differently
