Current dual tobacco use: Proportion of cigarette smokers who use smokeless tobacco by current industry, U.S. working adults aged 18 and over, 2010
† Estimates with a relative standard error of greater than 50% are suppressed.
– Estimated confidence intervals not calculated because estimated proportion of cigarette smokers who use smokeless tobacco in this industry is zero.
a Estimates with a relative standard error of more than 30% but less than or equal to 50% are statistically unstable due to small sample size and should be used with caution as they do not meet the standards of reliability.
Note: Numbers presented are annual estimates for 2010. Estimated proportions represent those current cigarette smokers who use smokeless tobacco. They are weighted and not age-adjusted. Current smokers are those who smoked at least 100 cigarettes in their lifetime and are currently smoking cigarettes every day or some days at the time of the survey interview. Smokeless tobacco users are those who ever used snuff or chewed tobacco in their lifetime and are currently using snuff or chewing tobacco at the time of the survey interview. Working adults are those who were employed in the week prior to the survey. Estimated populations represent current U.S. workers aged 18 years and over by industry.
