Well, this might not be popular opinion and many will think it's a sham, but I've used Allen Carr's book to quit drinking... His is actually more known for his 'stop smoking' book and I've known people who used it successfully as well. From my personal experience, a lot of this is in the head, so if your friend is open minded and really wants to quit then Carr's book just might be the answer. I can only vouch for his 'method' that helped me with a drink, not smoke, but it's the same principle. Just my 2c.
