What he did makes sense... for someone looking for an excuse to smoke again. It doesnt matter how you quit, you have cravings for years, if not the rest of your life. Quitting again the "right" way isnt going to solve those problems, so to me, that just sounds like an excuse because he WANTED to smoke.
However, to give him benefit of the doubt, its possible that he MAY have actually thought that if he quit the right way he wouldnt have cravings. There are times when I would be willing to go through the crap of quitting again (i am currently smoke free) if I thought it meant I would never want it again after. I have been smoke free for about a year and a ahlf, and I still want one every day. This isnt just some bad habbit you need to get out of your system, its a real, hard core, addiction. The same way the sober alcoholic is still an alcoholic after 5 years, I will still be a smoker after 5 years of being smoke free... and 10 years later... i will still be a smoker. But those marks seem so far away, I still cant make it even 1 year without a cig, much less 5 or 10.
