patches, gum, Chantix, electronic cigs, hypnosis,etc. But the only thing that makes any difference is person's attitude and unwavering commitment to quitting. The recent studies have shown that the most successful quitters are those that quit cold turkey. Yes, cold turkey! Without all the expensive remedies.
Bottom line is, as I said before, a person can use any help they want, but without their decision to quit, none of the tricks will work. You can do nothing to persuade your boyfriend.
