Prevalence of use of any stop-smoking medications (SSM) (black bars) and of each SSM (coloured bars) among those making a quit attempt (QA) (n=1737), across the study period. Diagonal patterned sections of bars indicate more than one type of medication was used during a particular survey wave (i.e. the bars overlap); n= 3087 for prevalence of at least one QA among all smokers (black solid line); n= 1706 for prevalence of 2+ QAs among quit attempters (black dashed line). *Battery of items used to assess SSM use during this survey wave differed somewhat from battery used during preceding wave.
