This study is from Italy. It sought to identify and quantify the chemicals released on a closed environment from the use of e-cigarettes – the findings? There’s little to be concerned about with regard safety. This research again confirms the type and quantity of chemicals released are by far less harmful to human health compared to regular tobacco cigarettes. In fact, it “could be more unhealthy to breath air in big cities compared to staying in the same room with someone who is vaping.”
