Repeated point-prevalence of switching away from smoking after electronic nicotine delivery systems (ENDS) purchase

For the majority of participants, product use status at 12 M was consistent with use patterns in the second year: most adults who smoked at baseline and were switched at 12 M reported repeated point prevalence-switching over Y2, while any smoking at 12 M- especially daily smoking- was usually followed by repeated point prevalence-smoking. These findings indicate that switching and smoking behavior is generally maintained and remains stable one year after purchasing ENDS.
