Vaping while still smoking unlikely to help quitters: study

Over time, most of these "dual users" tend to go back to only smoking cigarettes, according to the study published in the journal ERJ Open Research. The international team of researchers reviewed existing data on smoking and vaping before combining the results. After four to eight months, only three percent of dual users quit smoking, they found. Over that period, eight percent of people who exclusively vaped quit, while six percent of those who only smoked cigarettes managed to kick the habit.
