Trends in the use of e-cigarettes for stopping smoking, current vaping among ex-smokers, and uptake of vaping after smoking cessation, October 2013 to May 2024. Panels show the prevalence of (A) e-cigarette use in quit attempts by past-year smokers (n = 12,593); (B) current vaping among ≥ 1y ex-smokers (n = 41,658); (C) current vaping among < 1y ex-smokers who did not use e-cigarettes in their most recent quit attempt (n = 1,782); and (D) current vaping among ≥ 1y ex-smokers who quit smoking before e-cigarettes started to become popular in 2011 (n = 29,029). Trends in (A), (B), and (D) were modelled monthly (restricted cubic splines; five knots); (C) was modelled annually (three knots) on account of small samples. Lines represent modelled weighted proportions. Shaded bands represent 95% confidence intervals. Points represent unmodelled weighted proportions
