PURPOSE: To assess indoor secondhand smoke (SHS) concentrations within hospitality venues in Greece before vs. after the adoption of the 2010 smoke free legislation.
METHODS: We performed a follow-up study of venues in Greece after the adoption of a smoke free law (n=150 at baseline, n=75 followed up at 2-year). Indoor PM2.5 concentrations attributable to SHS smoke was assessed in each venue, every six months for two years (n=455 measurements).
RESULTS: Following the implementation of the 2010 smoke-free legislation, mean PM2.5 concentrations attributable to SHS fell from 175.3µg/m3 pre-ban to 84.52µg/m3 immediately post-ban, however SHS concentrations measured in the venues increased over subsequent waves (103.8µg/m3 and 158.2µg/m3 respectively). SHS concentrations at the 2 year follow up were higher in bars (beta=91.6 µg/m3), and cafes (beta=59.6 µg/m3), than restaurants after controlling for potential influential factors such as ventilation, time of day, day of week, city and venue type. Controlling for the above factors again, all post-ban measurements were still lower than the pre-ban (Wave 2 beta:-118.7, Wave 3 beta:-87.6, and Wave 4 beta:-69.9).
CONCLUSIONS: Following the introduction of the smoking ban in Greece in 2010, indoor PM2.5 concentrations attributable to SHS decreased, and despite their recent increase still remain lower than pre ban concentrations.
CLINICAL IMPLICATIONS: The introduction of the smokefree legislation in Greece has led to a reduction in population exposure to SHS within public places.
