On March 2 of 2007, with the implementation of Law 66, Puerto Rico became a smoke-free island by completely banning indoor smoking in public places such as bars, pubs, casinos, hotels, work places with more than one employee, and cars with any passenger under the age of 13 . According to the literature, the immediate impact of smoke-free workplace policies has been to dramatically reduce the exposition to SHS for customers and workers (10-17). Many studies have used the level of respirable particulate matter ([PM.sub.2.5]) as the main indicator of exposure to SHS because it has been demonstrated that smoking is one of the main sources of indoor levels of [PM.sub.2.5] (10). For example, bars in the state of New York experienced an average reduction of 84% in their [PM.sub.2.5] levels after the Clean Indoor Air Act was implemented in July of 2003 (11). In the case of Austin, Texas, bars experienced a reduction from 71% to 99% in their [PM.sub.2.5] levels after a smoking ban was implemented (12). In another study (13), Irish-theme pubs around the globe located in countries or cities with smoke-free legislation were compared with similar pubs in places without smoke-free ordinances. In this case, the results showed an average 91% reduction in [PM.sub.2.5] levels. In March of 2006, a smoking ban was implemented in Scotland, which substantially covered enclosed places including pubs. Evidence shows that, as a result, Scottish pubs experienced an average of 86% reduction in [PM.sub.2.5] levels (14). In Italy, a year after the implementation of an all smoke-free workplace policy in January of 2005, there was an average of 68% reduction in [PM.sub.2.5] levels across bars, restaurants, game rooms, and pubs (15). The main claim of this study is that the smoke-free workplace policy implemented in March of 2007 was effective in reducing the exposure to SHS in restaurants, pubs, and discos in the metropolitan area of San Juan, Puerto Rico. The specific research objectives of the study were three. First, to measure and compare the restaurants, pubs, and discos in the metropolitan area of San Juan at baseline (before the smoke-free workplace policy was implemented) in terms of the levels of respirable particulate matter (PM), the number of smokers, the number of customers, and establishment area. Second, to measure the change in levels of PM, the number of smokers, and the number of customers before and after March 2007. And third, to measure the effect of the smoke-free workplace policy on the level of PM controlling for the number of customers and establishment area.
