Makers of e-cigarettes claim that their products are safe, but one study shows that dozens of popular e-cigarette products are contaminated with bacterial and fungal toxins that cause lung disease.
,” said Dr. David Christiani, study author and professor of environmental genetics at the Harvard T.H. Chan School of Public in Boston.
They found that 17 of 75 products, 23%, contained traces of endotoxin, a potent inflammatory molecule found in bacteria, and 61 of 75 products, 81%, contained traces of glucan, a toxic substance found in the cell walls of most fungi. Exposure to these microbial toxins has been associated with a myriad of health problems, including asthma, reduced lung function, and inflammation., indicating that raw materials used in the production of flavors might be a source of the contamination.
“In addition to inhaling harmful chemicals, e-cig users could also be exposed to biological contaminants like endotoxin and glucan,” said Lee. “These new findings should be considered when developing regulatory policies for e-cigarettes.” “There needs to be much stronger regulation of the production and purity of the compounds used in e-cigarettes," Christiani said."People should not assume that e-cigarettes are safe,”
