Most smokers suffer from Vitamin E deficiencies. But when you give them an extra Vitamin C supplement (maybe one pill in the morning and 1 at night), this E deficiency goes away completely. Vitamin E is used in collagen production.
My opinion is that smokers have a higher bacteria count in their lungs, and your body has to constantly repair them. Vitamin C kills the bacteria. Yea.
Bacteria creates acids, and a chronic state of acidic lungs can lead to a lung fungus or sinus fungus.
The mayo clinic says that most chronic sinus infections are caused by a fungus.
I think Acidic lungs complicated by a fungus leaves your lungs more vulnerable to a lung cancer.
*****
On a second-note, beta-carotene (a pre-cursor of Vitamin A, and an anti-inflammatory), increases the risk of lung cancer in smokers.

You can cure the E-defficiency, and kill the lung fungus, and H202 therapy can cure emphysyma, and greatly decrease the chance of obtaining lung cancer. Even if you don't quit, there are steps you can take to improve your quality of life. Quitting smoking is of course a better solution(but everybody knows that part).
Also, smokers live an average of 5-years less than non-smokers. There aren't any studies on smokers who take extra vitamins though (or whether these smokers are also obese or heavy drinkers).
One bizzarre study shows that ex-smokers are less likely to develop thyroid cancer than non-smokers and active smokers are even less-likely. It's a counter-intuitive, strange piece of trivia.
*****
As Ted said, taking a b-3, and/or a B-complex may be helpful, along with an extra C. This may reduce congestion along with other benefits, helping make the process of quitting easier.

One method to quit smoking is count-the-clock... count the number of minutes between your first 2 morning cigerettes... if it's 30 minutes, then you can't smoke any quicker than 30 minutes between ciggerettes. Gradually increasing throughout the day. In a week or 2, maybe you can get down to a few cigarettes per day.
Then... don't bring them to work, and you can cut down to 2 or 3 in a few more days. That is the count-the-clock method. Of course, no method works for everybody.

1. One must really want to stop smoking. Without it, no need to bother in trying to stop smoking.
2. for a first week I used nicorette patches, drank molases, ACV,
3. The first day without patch I was very nervous unable to concentrate,... So I cut a patch in half and used it for few hours and before bed time watched- listened a DVD with hypnosis: Stop smoking (English author it costed 5 EUR).
4. I socialize with smokers mostly, and they dont bother me at all.
