      Background:
      In 2012, North Dakota enacted a comprehensive smoke-free law. In 2014, the 3rd phase of a stratified random sample longitudinal study of tobacco smoke pollution in restaurants and bars was conducted (n = 107). Phase 1 was conducted prior to passage of the law, Phases 2 and 3 were conducted 3 and 21 months post-implementation respectively.

      Methods:
      Tobacco smoke pollution levels were assessed by collection of particulate matter 2.5 microns aerodynamic in diameter or smaller using SidePak [TM] AM510 Personal Aerosol Monitors.

      Results:
      The geometric mean PM~2.5 ~was 6.9 microns/m[3]. Statistically significant reduction in mean PM~2.5~ occurred from Phases 1 to 3 but not from Phases 2 to 3 in all venues and for bars alone. A significant increase in indoor PM~2.5~ occurred when there was outdoor smoking or ashtrays within 20 feet of the venue entrance, exit, or windows and when smoking was observed within designated outdoor smoking shelters. Multi-level linear models found that the presence of a local ordinance and venue type were predictors of PM~2.5~ in Phase 1 but not in Phases 2 or 3. Significant decreases in mean PM~2.5~ by rurality occurred between Phases 1 and Phase 3. In contrast with the Phase 1 study, there were no significant differences in PM~2.5~ by rurality in only Phase 3.

      Conclusion:
      This longitudinal study is the largest rural pre and post-law rural study known globally. Passage of the comprehensive statewide smoke-free law effectively reduced PM~2.5~ levels in restaurants and bars statewide.
