Notes: Fifty current nonsmokers answered “Don’t know” and 53 current nonsmokers did not answer to the question about how many days they were exposed to SHS at work, and three others answered “Don’t know” to the question about the smoking policy at work, thus a total of 419 (370 + 49) rather than 525 current nonsmokers are included in this study. Results presented in this table represent simple aggregation of the survey results, and no sampling weighting was used.
