| ONS survey: smokers and <12 month ex-smokers; 1999 n = 1072; 2002 n = 1022. | ||||
| Estimated number of smokers is 12.5 million in both years. Estimated smoking prevalence fell by approximately 1% but there was a rise in the adult population which would be expected to offset this. Figures are integers to avoid the impression of spurious precision in estimates. | ||||
| *This is different from the published figure because the latter is not limited to smokers who made a quit attempt in the year. | ||||
| †This assumes minimal use of both OTC and prescription medication in the same quit attempt. | ||||
