From Michael Siegel's "The Rest of the Story" blog, good news for vapers and those we love:

These results should be viewed as preliminary, especially because only one brand of electronic cigarettes was tested....
Nevertheless, these results seem to suggest that electronic cigarettes at least have the potential to present little risk to bystanders. Not only can we say that there is currently no evidence that passive vaping is harmful, but we can now say that the first study to examine passive vaping under realistic conditions found no chemicals of concern in the ambient air.
The rest of the story is that there is no current evidence that passive vaping poses any significant threat to the health of bystanders. Thus, I do not see any public health justification for banning vaping in public places at the present time.
