Breaking News: New study shows no risk from e-cigarette contaminants
The study, by Prof. Igor Burstyn, Drexel University School of Public Health, is available at the Drexel website, here (pdf). Burstyn reviewed all of the available chemistry on e-cigarette vapor and liquid and found that the levels reported — even in those studies that were hyped as showing there is a danger — are well below the level that is of concern.
And that assessment applies to the vaper himself. The exposure to bystanders is orders of magnitude less and of no concern at all.
The paper is technical, of course, but I believe it does a great job of communicating for readers at many levels. It puts the results in very clear and useful terms — exactly what policy makers need for making decisions.
