2). Carcinogens and chemicals such as nicotine, formaldehyde, and diacetyl have been found in e-cigarettes that have been proven to be of harm to human health. For example, diacetyl has been showed to cause acute-onset bronchiolitis obliterans, which is a severe and irreversible obstructive lung disease (Rowell and Tarran, 2015, p. 8). Chemists have found various levels of chemical metals in vapor including chromium, nickel, tin, silver and aluminum when the heating elements of e-cigarettes are operated at high voltage. These chemical findings have also been related to findings in combustible cigarette usage. E-cigarettes also may potentially contain harmful compounds that are not found in tobacco products, such as propylene glycol. Propylene glycol allows for the formation of a visible vapor and is known to be a respiratory
