The results of this study are presented in an article entitled "Real-Time Measurement of Outdoor Tobacco Smoke Particles", published in the May 2007 issue of the Journal of the Air and Waste Management Association. The article authors are Neil Klepeis, Wayne Ott, and Paul Switzer of Stanford University.

This study is the first published in-depth investigation of air pollution levels arising from outdoor smoking activity. The main finding is that levels of outdoor air pollution exposure can be substantial near an active smoker.
