A new research from Harvard T.H. Chan School of
Public Health has reported that popular electronic cigarette (e-cigarette)
products sold in the U.S. were contaminated with bacterial and fungal toxins. The
study has been published online in Environmental
The study had examined 75 popular e-cigarette
products and found that 27% contained traces of endotoxin and 81% contained
traces of glucan.
Endotoxin is a microbial agent found on
Gram-negative bacteria. Glucan is found in the cell walls of most fungi. Exposure
to these microbial toxins has been associated to a number of health problems
such as asthma, reduced lung function, and inflammation.
E-cigarettes are battery- operated devices that
do not burn or use tobacco leaves but instead vaporise a solution, which a user
then inhales. The solutions contain propylene glycol, nicotine etc. which pose
significant health risks, including cancer.
