Figure 2: Potential adverse health-related outcome of waterpipes (Fakhreddine et al. 2014:1247) Effects on Indoor Air Quality - Discussion Dinning and recreational venues have the highest demands for indoor smoking from their customers. However, there is a controversy in whether to deal with this issue from a health point of view or from an economical point of view which is closely tied to the generation of revenue within that particular location. Some of the papers reviewed in this part discuss the health factors and argue in favor of a ban for smoking in public areas, considering the smoker and the second hand smoker. In terms of the economy, two studies are reported for having different effects on their revenue after the comprehensive or partial ban. In the previous section the health related effects of the three smoking aids have been discussed. It is worthwhile to study how smoking indoor had an effect on the policy makers. A research conducted by Bohac et al. (2010) tested three dining venue types for analyzing the PM (Particulate Matter) and the rate of SHS (Second Hand Smoker) drop before and after a ban of smoking on such areas. The researchers tested 255 social dining spots before and after the ban, which has resulted in a drop of 87.6% in the PM levels on average. A similar study conducted, in a bar/restaurant in Athens, by Konstantopoulou and Behrakis (2014) where they tested the amount of indoor air contaminants pre-ban and post-ban for two types of spaces; smoking zones and non-smoking zones. Overall, there had been a drastic drop in indoor air contaminants after the banning of indoor smoking, however, prior to the ban, 50% of the smoking contaminants were seen present in the non-smoking zones. Liu et al. (2014) conducted a field observation in Beijing over a period of 4 years; from 2006 to 2010 to identify the percentage of bars and restaurants have implemented the smoking ban policy after the topic of a ban in smoking became an area of interest in the WHO FCTC in 2006, in China. The following year, there was a voluntary rule for banning indoor smoking, The impact of smoking on indoor air quality in hospitality venues 825
