There's a chap like that where I work, he's had hypnotherepy, reckons it's ok as long as he keeps going once a fortnight, in this case costing about the same as the fags but if he stops going, back on the snout straight away.
I'm afraid that it can only be done with willpower in the end, all the patches, gum, hypnosis etc just prolong the inevitable. If there is no will power then he's a prisoner to the weed forever. However anyone can do it if they want it badly enough, will power is just a manifestation of will.
He needs to get into the frame of mind to do it, you don't give up smoking you becomer a non smoker. When al the work mates are lighting up don't envy them, pitty them, "look at those sad gits paying a fortune to filter poison through their lungs". "God, don't they know how bad they smell and how silly they look" etc etc. No one says it's easy, I wish him good luck, get brutal with it!
