^a An additional weight has been added to correct for response bias in the sub-sample providing a valid saliva sample (see
Section 4.5.1).

^b The sample base for these categories is too small for results to be shown.

^c Comparative general population data are not available for saliva cotinine from the 1999 survey itself, comparative data have
therefore been taken from the 1998 survey, in which no weighting was involved.
