A recent study said that electronic cigarette was not healthy, because its flavored vapor can cause irritation of mucous, although the FDA has approved its steam consumption. Thus the conclusion of the study was written by James F.Pankow, a professor of chemistry and civil engineering and environment at Portland State University. James explained that the aldehyde chemical vapor contained in the e-cigarette may be safe if eaten but not if inhaled. James and his team tested the chemicals contained in the thirty kinds of e-cigarette. He and his team called for the issuance of new rules to regulate it.
The new study is authored by James F. Pankow, a professor of chemistry and civil & environmental engineering at Portland State University. Details of the finding are published in Tobacco Control online journal on April 15.
