(33,643 posts)IMHO, if you no longer smoke regular cigarettes with anything like 'regularity', then you've successfully 'quit smoking'.
That blurb above doesn't define 'quitting' either. What % of the people who 'succeeded' are actually OFF the patches/lozenges/etc? Do you have to be to meet the criteria, IOW?
Similarly with vaping, what if one used to smoke, but have since switched completely to vaping ... for years. Is that NOT 'quitting smoking'? How many years or months must it be? Does having had 1 cig a month ago in a time of stress 'count against you', even its the only 1 you had in 4 years? What if have weaned to 0% nicotine, but still vape? Is that quitting? To a researcher, it all depends on the standards/methodology.
There's no real 'common definition', and that makes comparing studies ... tricky.
