Hi Missi,
Remember that he won't recover unless he truly wants it. However, even if he wants it, he might have a very hard time recovering.
I would suggest you offer him one of those new Electronic Cigarettes. They use water vapor instead of smoke, and have just enough nicotine in them to curve his cravings without being truly harmful. That is what I did to quit. He might come to one of these conclusions at one point, and then stop:
1) This thing sucks, there is no point in using it. However, I don't know if I want to smoke again.
2) I think I will stick to this (and eventually, he forgets to use it continuously).
I came to the second conclusion, but I know people who came to the first.
The E-Cigarette helped me to quit without feeling like I was going cold-turkey.
Hope this helps.
