There are a growing number of research studies which indicate that e-cigarettes pose negative health consequences for users. Medical Daily states that when “e-cigarettes first emerged in 2004” they “quickly became popular” as a so-called healthy alternative for individuals who wanted the experience of smoking tobacco without inhaling the toxins associated with traditional cigarettes. Unfortunately, a number of studies have suggested that e-cigarettes create negative health concerns. Dr. Irfan Rahman, professor of Envinronmental Medicine at the University of Rochester, studied how e-cigarettes may affect oral health. “We showed that when the vapors from an e-cigarette are burned, it causes cells to release inflammatory proteins, which in turn aggravate stress within cells, resulting in damage and that could lead to various oral diseases,” he said. Dr. Rahman also co-authored a study which examined the artificial flavoring used in e-cigarettes. That study indicates that the flavors induce tissue damage and have a toxic effect on white blood cells – the worst impact came from cinnamon, vanilla and buttery flavored “e-juices”. The study also noted that the Food and Drug Administration has not approved e-cigarettes as a smoking cessation aid.
