One shouldn't judge unless they have walked in his shoes. I got lung cancer 17 years ago...had chemo and my right upper lobe removed and went back to smoking as soon as I could drive(my hubby wouldn't bring me any). The doctor had told me that it would probably come back in two years or so anyway, so I decided not to bother quitting. Well, I'd never had any luck quitting before when I'd bothered to try. Tried patches, pills, hypnosis, acupuncture, cold turkey to no avail, until e-cigarettes! I know that I have been lucky so far, and it may not last, but I've had a pretty long run and something is going to take each and every one of us, sooner or later. I LIKED to smoke, but I LOVE Vaping. I need the hand-to-mouth as well as the nicotine. I may cut back the amount of nicotine eventually (12 mg. now), but I have my doubts that I will ever give it up completely!
