In 2020, of all respondents who had tried to quit smoking for one day or longer in the past year (i.e., 44.5%a of smokers and recent quitters), 15.4% were still quit at the time they were surveyed. This represents no significant change in quit success from 2019.31

While comparison from 1999 to 2020 is not possible due to changes in question coverage and availability of data,* since 2004, quit success appears to have generally remained around 10-14%, with some year-to-year fluctuation (Figure 5.13).
