Trend in smoking prevalence 1994-5 to 2003-4.
Annual reduction as a % of 1994-5 prevalence
Here we estimate the reduction as a fraction of the prevalence in 1994-5, and so the numbers are different, but the inter-country differences remain.
Canada is clearly ahead on this basis.
A one percent rate of reduction as in NZ over the past 10 years means it could take over a century to reduce smoking to zero.
