  1. ^ Column total exceeds the number of current and former smokers because subjects chose multiple methods.
  2. * Population estimates are reported to the last digit to aid in re-analysis of results. They are not intended to imply a level of precision beyond what can be achieved from the survey.
  3. + CI is an approximation based on the unweighted survey count.
  4. CI – confidence interval.
  5. ST – smokeless tobacco.
