With names like “Banana Pudding,” “Blueberry Cinnamon-Streusel Muffin” and “Butter Crunch,” the flavoring ingredients in electronic cigarettes sound not only harmless but immensely appealing. But some of the liquids used in e-cigarettes may in fact have highly toxic effects on human cells tested in a lab, a new study reveals.

Researchers in North Carolina found that some of the ingredients used in so-called “e-liquids” are more toxic than nicotine alone and many of them are more toxic to human cells than the main ingredients in these liquids, which are propylene glycol and vegetable glycerin, according to the findings, published today (March 27) in the journal PLOS Biology.
